• MSI to Bundle Intel Optane Memory 16 GB Cache Drives with Select Motherboards (AnandTech)

    MSI this week announced plans to bundle Intel Optane Memory 16 GB caching drives with select Intel 200-series chipset motherboards. The company claims that the drives will not increase prices of motherboards significantly, but will bring tangible performance benefits when it comes to boot times and application launches versus systems employing HDDs.

    MSI will add Intel’s Optane Memory 16 GB drives to its Z270 Tomahawk Opt Boost, B250M Bazooka Opt Boost, as well as B250M Pro Opt boost motherboards, which means the company will be hitting gaming, mainstream, and commercial PCs. The consumer Intel Optane Memory caching drives were not designed to replace conventional SSDs, but were developed to enable hybrid storage solutions featuring fast solid-state memory as well as a slower storage device with SATA interface (i.e., an HDD, but SSHDs and even SATA SSDs are formally supported as well). The Intel Optane Memory 16 and 32 GB drives cache frequently used data (i.e., frequently used LBA sectors where Windows boot files and frequently launched applications reside) with the help of Intel’s software and PCH and therefore speed up PCs with mechanical hard drives. Performance-wise, Intel’s Optane Memory 16 GB drive offers up to 900 MB/s sequential read and up to 145 MB/s sequential write speed, but keeping in mind that the drive is used for caching, random read speeds and overall read latency are what matter most.

    Intel Optane Memory Specifications
    Capacity 16 GB 32 GB
    Form Factor M.2 2280 B+M key
    Interface PCIe 3.0 x2
    Protocol NVMe 1.1

    Memory 128 Gb 20nm Intel 3D XPoint
    Sequential Read 900 MB/s 1350 MB/s
    Sequential Write 145 MB/s 290 MB/s
    Random Read 190k IOPS 240k IOPS
    Random Write 35k IOPS 65k IOPS
    Read Latency 7µs 9 µs
    Write Latency 18µs 30 µs
    Active Power 3.5 W 3.5 W
    Idle Power 1 W 1 W
    Endurance 182.5 TB 182.5 TB
    Warranty 5 years
    MSRP $44 $77

    While MSI bundles the Optane Memory 16 GB drives with select 200-series motherboards, it should be noted that the drives are only supported by Intel’s Core i-series Kaby Lake processors (so, no Celeron or Pentium) and Microsoft Windows 10 64-bit OS. In addition, the Optane Memory drive must be supported by the UEFI firmware of the motherboard.

    Based on our own test results, Intel’s Optane Memory 32 GB caching drive can bring performance an HDD-based system up to the level of mainstream SSDs in SYSmark, but like most hybrid storage sub-systems, this happens only with frequently used files or programs. The good news is that Intel’s Optane 16 GB SSD (retail $47) comes for free(ish) with select MSI’s motherboards, essentially bringing an inexpensive performance improvement to equally inexpensive systems with HDDs.

  • Western Digital Starts Shipments of HGST Ultrastar He12 12 TB HDDs (AnandTech)

    Western Digital on Wednesday announced that it had begun to ship its HGST Ultrastar He12 hard drives with 12 TB of capacity. The HDDs are the first drives to employ eight platters, so the fact that Western Digital is now shipping them is important not only for its datacenter customers who need massive storage capacities, but also because the drive represents a significant step forward from a technology point of view.

    The HGST Ultrastar He12 is based on Western Digital’s fourth-generation HelioSeal technology, which uses eight perpendicular magnetic recording platters with 1.5 TB capacity each. To add the eighth platter, Western Digital had to redesign internal components of its HDDs (including arms and heads) significantly. In addition, the company increased areal density of the platters, which improved the sequential read/write performance of the new hard drives. In particular, Western Digital claims that the HGST Ultrastar He12 has a sustained transfer rate of 255 MB/s, an average latency of 4.16 ms, as well as an average seek time of around 8 ms.

    Just like other enterprise-class nearline drives, the Ultrastar He12 features a 7200 RPM spindle speed as well as all the technologies currently found in such hard drives from HGST, including a special micro-actuator that improves the accuracy of head positioning in multi-drive environments (which naturally improves performance, integrity, and reliability), rebuild assist mode to speed up RAID recovery time, and others. Finally, the new drives have SED options as well as Instant Secure Erase feature so to either quickly redeploy or retire a HDD.

    Power Rating Idle 5.3 W 6.1 W
    Operating 7.2 W 9.8 W
    MTBF 2.5 million hours
    Warranty 5 Years

    The increase of hard drive capacity by 20% to 12 TB brings substantial benefits to operators of cloud and exascale datacenters because such HDDs enable them to boost their storage capacity by 20% (or more, assuming that they are using drives with lower than 10 TB capacity today) without expanding footprint of their building or significantly increasing their power consumption. For example, a standard server rack can store 2400 TB of data if fully populated with 10 TB HDDs today. Meanwhile, if 12 TB hard drives are installed into the same rack, its total storage capacity increases to 2880 TB at the same power and at the same space.

    Since Western Digital’s HGST Ultrastar He12 are aimed at large enterprises, the company does not advertise their recommended prices; the prices customers will pay depends on the number of drives purchased as well as some other factors. Since Western Digital will eventually offer helium-filled HDDs with eight platters to other kinds of customers too, so once this technology trickles down the general public will be able to take advantage of the fourth-generation HelioSeal platform as well.

    Later this year Western Digital plans to start shipments of its HGST Ultrastar He12 drives featuring shingled magnetic recording (SMR) platters and 14 TB of capacity. These drives are designed primarily for archival applications, where data is written sequentially in huge chunks (and is hardly ever updated) and where the peculiarities of SMR do not have a major impact on performance. The upcoming SMR HDDs will have to be managed by their hosts and therefore far not all customers of Western Digital are going to be able to take advantage of them.

  • AT20 Giveaway Day 3: Intel Core CPUs, SSDs, & Optane Memory Too (AnandTech)

    Good morning everyone! We’re now on day 3 of our 20 day celebration of AnandTech’s 20th anniversary.

    After yesterday’s HTC U Ultra giveaway, today we’re back to PC parts, courtesy of Intel. For today’s giveaway the 800lb gorilla has contributed a true silicon sampler, sending us CPUs, SSDs, and even some Optane Memory cache drives to give away to you.

    • 2x Intel Core i7-7700K
    • 2x Intel SSD 600p 512GB
    • 2x Intel Optane Memory 32GB

    The AnandTech 20th Anniversary - Intel Giveaway

    Intel Core i7-7700K

    First up, Intel’s Core i7-7700K needs no introduction. Intel’s flagship consumer CPU is still the chip to beat for all but the most heavily threaded workloads, thanks to the high IPC of Intel’s architecture combined with the equally high clockspeeds afforded by Kaby Lake. The i7-7700K will turbo boost to 4.5GHz, and as this is an unlocked processor, you can should must always overclock it even further.

    Core i7-7700K Specifications
    IGP L3 TDP
    i7-7700K 4/8 4.2/4.5 HD 630 8 MB 91 W

    As a reminder, retail box i7-7700Ks do not include a cooler, so along with a compatible motherboard you'll need a 3rd party cooler as well to complete the ensemble.

    Intel SSD 600p 512GB

    Second on our list of prizes is a pair of Intel 512GB 600p SSDs. The 600p is from Intel’s mainstream SSD family, combining an Intel-customized Silicon Motion SM2260 controller with Intel/Micron’s own 3D TLC NAND. These are single-sided M.2 2280 drives, so they’ll fit in virtually all M.2-equipped motherboards and laptops. And as one of what’s still a relatively small number of NVMe-capable PCIe 3.0 x4 drives on the market, the 512GB 600p can easily sustain reads over several-hundred megabytes-per-second.

    Intel SSD 600p 512GB Specifications
    Form Factor single-sided M.2 2280
    Controller Intel-customized Silicon Motion SM2260
    Interface PCIe 3.0 x4
    NAND Intel 384Gb 32-layer 3D TLC
    SLC Cache Size 17.5 GB
    Sequential Read 1775 MB/s
    Sequential Write (SLC Cache) 560 MB/s
    4KB Random Read (QD32) 128.5k IOPS
    4KB Random Write (QD32) 128k IOPS
    Endurance 288 TBW
    Warranty 5 years

    As Billy Tallis noted in our review of the drive, the 600p “offer[s] peak performance that is as high as promised” but do bear in mind that these are drives meant for consumer systems. So best not to try running your database server off of one.

    Intel Optane Memory 32GB

    Finally, we have a pair of Intel’s recently-released Optane Memory cache drives. Built using Intel’s newly-developed next-generation 3D XPoint memory technology, Intel has opted to start the consumer rollout of the technology by building cache drives, which maps well to the higher endurance and higher serial performance of 3D XPoint.

    Intel Optane Memory Specifications
    Capacity 32 GB
    Form Factor M.2 2280 B+M key
    Interface PCIe 3.0 x2
    Protocol NVMe 1.1
    Controller Intel
    Memory 128Gb 20nm Intel 3D XPoint
    Sequential Read 1350 MB/s
    Sequential Write 290 MB/s
    Random Read 240k IOPS
    Random Write 65k IOPS
    Read Latency 9 µs
    Write Latency 30 µs
    Active Power 3.5 W
    Idle Power 1 W
    Endurance 182.5 TB
    Warranty 5 years

    It’s important to note that to take full advantage of these drives, you will need a Kaby Lake Core-series processor and a supported chipset, as that’s the only platform to support Intel’s full Optane cache mode. Otherwise the drives can be used in some other systems, but they’d only show up as a small 32GB NVMe drive. According to our resident SSD-sommelier, Billy Tallis, these drives tend to be best paired with something like a Core i3 processor in a lower-end system, to transparently speed up performance on a HDD boot volume.

    Finally, as with our other giveaways, today’s giveaway is only open for 48 hours, so be sure to enter soon. However please note that for legal reasons, we’re only able to open these giveaways to residents of the United States.

    Good luck to everyone! And be sure to check in Monday for our next giveaway.

  • Voici ce qui serait le premier véhicules autonome piloté par des produits Apple (MacBidouille)

    Apple a obtenu un permis de tester des véhicules autonomes sur les routes de la Californie.
    Bloomberg a obtenu des photos de ce qui serait le premier véhicule de test de la société, sortant du campus de Cupertino.

    Il s'agit d'un SUV Lexus, bardé d'une électronique peu discrète.

    On verrait des caméras, deux radars et sur le toit un Lidar à 64 canaux. Ce serait un mélange de produits commercialisés par des tiers et d'autres qui semblent avoir été modifiés maison.

    Cette plateforme de tests en est à ses débuts ce qui explique son absence d'intégration à la voiture. Les autres acteurs de ce marché ont déjà commencé depuis un moment à pousser l'intégration des composants dans le véhicule pour les rendre plus discrets.

    Apple va devoir non seulement refaire son retard sur les autres sociétés travaillant dans ce domaine depuis de nombreuses années mais aussi atteindre des standards très élevés pour convaincre les fabricants automobile d'intégrer ses systèmes.

  • L'iPhone 7 Red et le SE améliorés ne devraient pas donner de coup de fouet aux ventes (MacBidouille)

    IDC a publié ses estimations de ventes de smartphones au premier trimestre.

    L'organisme estime que les ventes d'iPhone n'ont pas connu de progression significatives par rapport au premier trimestres de l'année dernière. Elles seraient à la hausse de seulement 0,8% alors que Samsung plombé par le note 7 arrive tout juste à garder l'équilibre grâce à des ventes record de S8.
    Ce sont encore une fois les marques chinoises, Huawei, OPPO et Vivo qui progressent le plus et supportent la croissance du marché des smartphones à elles seules.

    Il n'est pas surprenant qu'Apple n'ait pas fait mieux. Ce ne sont pas le SE à peine amélioré ou le 7 Red qui avaient des chances de relancer en grand les ventes. C'est d'autant plus vrai que les rumeurs alléchantes sur un futur iPhone 8 ont eu tendance à créer un effet d'attente.

  • Intel Announces Q1 2017 Financial Results: Record Quarter (AnandTech)

    Today Intel announced their earnings for Q1 of their 2017 fiscal year, and the results were good. Intel delivered record revenue for the quarter, of $14.8 billion, up from $13.7 billion a year ago. Intel is a company that loves their margins, and they were once again over 60% for the quarter, coming in at 61.8%, which is 2.5 percentage points higher year-over-year. Operating income was up 40% to $3.6 billion, and net income was up 45% to $3.0 billion, which resulted in earnings-per-share of $0.61 for the quarter, also up 45% from a year ago. This is even though Q1 2016 was 14 weeks, versus 13 weeks in 2017.

    Intel Q1 2017 Financial Results (GAAP)
      Q1'2017 Q4'2016 Q1'2016
    Revenue $14.8B $16.4B $13.7B
    Operating Income $3.6B $4.5B $2.6B
    Net Income $3.0B $3.6B $2.0B
    Gross Margin 61.8% 60.9% 59.3%
    Client Computing Group Revenue $7.976B -12.6% +5.7%
    Data Center Group Revenue $4.232B -9.34% +5.8%
    Internet of Things Revenue $721M -0.7% +10.8%
    Non-Volatile Memory Solutions Group $866M +6.1% +55.5%
    Intel Security Group $534M -2.9% -0.6%
    Programmable Solutions Group $425M +1.2% +18.4%
    All Other Revenue $42M -35.4% -16%

    Intel’s Client Computing Group continued to have gains, with revenue for the quarter up 6% to $7.976 billion. Significantly for Intel, operating income for this segment jumped from $1.885 billion a year ago, to $3.031 billion this year. While we’ve seen the company forced to slow down its movement to smaller processes, the current 14nm node has been well refined and the Kaby Lake processors have been solid performers. The next generation 10nm node is looking very promising though, with Intel claiming 25% better performance and 45% lower power consumption versus Kaby Lake thanks to the density improvements.

    The Data Center Group also had gains, with revenues up 6% year-over-year to $4.232 billion, although the growth has slowed somewhat. Operating income for the group was $1.487 billion for the quarter, down from $1.764 billion a year ago. This will be an interesting space to watch with increased competition in both the x86 and ARM space, but Intel will be releasing new Xeon chips as well with a change in branding.

    The Internet of Things Group continued to show gains as well, with revenue up 11% year-over-year to $721 million, and up 35% since Q1 2015, so in two years they have seen some substantial growth in this segment.

    Non-Volatile Memory Solutions Group had the largest jump in revenue, with revenue up 55% to $866 million. However, this group also saw an operating loss increase to $129 million, compared to a $95 million loss a year ago. This should be an exciting segment to watch though with Intel bringing their Optane products to market, with both the DC P4800X SSD and Optane caching memory. If you haven’t checked out those reviews yet, they are well worth the read, and 3D XPoint definitely brings some advantages even on a Gen 1 product.

    Intel’s Security Group is showing its final mention in their earnings, since Intel’s divestiture of the group closed on April 3, 2017, and subsequently it will fall in to the “All Other” category starting next quarter. Revenue for this group was pretty flat, at $534 million, compared to $537 million a year ago. Operating income was up to $95 million though, from $85 million last year.

    The Programable Solutions Group, which is Intel’s FPGA segment, had a revenue increase of 18% to 425 million, and an operating income of $92 million, compared to an operating loss of $200 million a year ago.

    Finally, the All Other category had revenues of $42 million and an operating loss of $1.082 billion.

    Looking towards next quarter, Intel is forecasting revenues of $14.4 billion, plus or minus $500 million, and a gross margin around 62%, give or take a couple of points.

  • Acer Announces Predator X27 Monitor: 4K@144 Hz with DCI-P3, HDR10, & G-Sync (AnandTech)

    At its annual Next@Acer event, Acer formally introduced the Predator X27, its new flagship gaming display. The company's first HDR monitor, the Predator X27 is Acer's implementation of NVIDIA's prototype HDR monitor design, which we first saw back at CES 2017. So like NVIDIA's prototype, Acer is aiming for the top with this monitor, offering 4K, HDR, a wide color gamut, and a high refresh rate all in a single display. Unfortunately for those of you eager to shell out for the Rolls-Royce of gaming monitors, you'll have to wait a bit longer; Acer is not announcing a release date or a price at this time.

    By the numbers, the Predator X27 offers a 4K resolution, a 144 Hz refresh rate, a 1000-nits brightness, and uses a quantum dot film to enable HDR10 and the DCI-P3 color gamut. To further appeal to gamers, the Predator X27 also supports NVIDIA’s G-Sync HDR technology as well as Tobii eye-tracking. The new unit is one of a few announced 4K displays to support such a high refresh rate along with HDR10 and NVIDIA’s G-Sync HDR technology.

    The Acer Predator X27 is based on AU Optronics’ M270QAN02.2 AHVA panel with a 3840×2160 resolution, 178°/178° horizontal/vertical viewing angles, up to 1,000 nits brightness, a 4 ms response time and a 144 Hz refresh rate. The monitor comes with a direct LED backlighting system with 384 zones, which ensures both high brightness as well as better contrast ratios through localized dimming. The backlighting system is further enhanced with a quantum dot film in order to give the monitor wide color gamut capabilities, allowing it to display 96% of the DCI-P3 color gamut, which pairs up nicely with its HDR support via the HDR10 format. Finally, the Predator X27 features NVIDIA's G-Sync HDR variable refresh rate technology.

    To take full advantage of the Predator X27 monitor, gamers are going to need an NVIDIA GeForce GTX 10-series graphics card with a DisplayPort 1.4 connector. NVIDIA & Acer are using every bit of bandwidth offered by DisplayPort 1.4 here, and even that's not enough; the X27's bandwidth requirements actually exceed what DisplayPort can provide. As a result the monitor (like all monitors based on the NVIDIA design) will use 4:2:2 chroma subsampling when gaming to stay within the bandwidth confines of DisplayPort 1.4. Meanwhile as you might expect, the display's lone HDMI 2.0 port is limited to 60Hz operation. In addition, expect the display to require a USB cable to control the Tobii eye-tracking hardware.

    To date, only Acer and ASUS have announced gaming displays powered by the M270QAN02.2 AHVA panel from AUO and supporting 4Kp144 with a 1,000 nits brightness, quantum dots, and HDR10. Such monitors in many ways represent a new generation of gaming displays that support not only a high resolution and refresh rate, but also the DCI-P3 color saturation, advanced backlighting with local dimming, and so on.

     DCI-P3: 96%
    Rec. 2020: 82%
    Inputs 2 × DisplayPort 1.4
    1 × HDMI 2.0

    Acer remained tight-lipped about pricing and availability timeframe of its Predator X27 display, but since AU Optronics is reportedly kicking off mass production of its M270QAN02.2 in July, it is likely that Acer, ASUS and other companies that use the panel may start selling their products on its base in late Q3, or early Q4 2017. As for pricing, we may well be talking about devices with MSRPs north from $1500 (some whispers say so), but Acer and its rivals yet have to announce their MSRPs.

  • Samsung Electronics se porte très bien (MacBidouille)

    Samsung a subi un énorme revers avec ses Galaxy Note 7 dont la société se remet d'ailleurs étonnamment vite si l'on regarde les records de vente du S8.
    Le conglomérat n'a toutefois pas trop souffert de ce revers de sa division mobile. En effet, dans le même temps, la division Samsung Electronics a annoncé avoir connu le meilleur premier trimestre depuis trois ans avec un chiffre d'affaire en hausse de 46%
    Si les bénéfices ont augmenté dans le même temps de 48%, ce n'est pas à cause d'un volume de vente en forte hausse, il a progressé de seulement 2%. Ce qui a fait exploser les résultats est tout simplement la pénurie de DRAM et de NAND Flash dont les cours ont grimpé énormément.

    Nous vous rappelons que ces composants connaissent depuis toujours des cycles plus ou moins longs de fortes hausses ou baisses sans fin. Actuellement, la bonne affaire est pour les producteurs et la moins bonne pour leurs clients et en fin de compte, les consommateurs.

  • Intel va sortir des Xeon d'or et de platine (MacBidouille)

    Actuellement, Intel propose de nombreuses gammes de processeurs, ATOM, Pentium, Core iX ou encore Xeon.
    Ces derniers sont à leur tour différentiés en plusieurs catégories. Les Xeon E3 sont destinés à prendre place seuls sur une carte mère. Les E5 peuvent être jumelés par deux (Apple les utilise quand même seuls dans ses Mac Pro) tandis que les E7 destinés à des stations de travail peuvent être jumelés par 8.
    Intel a décidé de changer la donne.

    Comme le montre cette capture, les prochains Xeon seront soit des versions Gold, soit Platinium. Les premiers équivalents des anciens E5 auront entre 14 et 22 coeurs physiques. Les Platinium devraient en avoir entre 22 et 28.

    Ces dénominations très bling bling ne sont pas habituelles chez Intel. La société semble vouloir se préparer à l'arrivée massive des processeurs AMD Ryzen destinés aux stations de travail et qui embarqueront énormément de coeurs aussi avec l'avantage d'être très efficaces pour les calculs massivement parallèles.

    En attendant, Apple qui a arrêté les Apple Watch Gold pourra ajouter ce nom à ses futurs Mac Pro.

    [MàJ] Il y aura aussi des modèles Bronze qui auront jusqu'à 10 coeurs et des silver qui en auront jusqu'à 12.

  • Micron Hires New CEO: Sanjay Mehrotra, SanDisk Co-Founder And Former CEO (AnandTech)

    In February, Micron CEO Mark Durcan announced his retirement after three decades with the company. Durcan had previously announced plans to retire in 2012 while serving as the company's president, but the death of then-CEO Steve Appleton prompted Durcan to postpone his retirement indefinitely to serve as Micron's CEO. Micron's board of directors has now selected Sanjay Mehrotra to be the new president and CEO of Micron. Durcan will step down and be replaced by Mehrotra effective May 8, 2017.

    Mehrotra's background includes co-founding SanDisk in 1988 and serving as its president and CEO from 2011 until its acquisition in 2016 by Western Digital. Prior to serving as CEO of SanDisk, Mehrotra had been the chief operating officer, head of engineering and chief of product development. Under Mehrotra's leadership SanDisk's annual revenue peaked at $6.6 billion and the company sold for $16 billion in 2016 to Western Digital. With long experience leading a major memory manufacturer, Mehrotra is one of the most highly-qualified candidates possible to take over at Micron.

    Outgoing CEO Mark Durcan will be stepping down as CEO and from the board of directors effective May 8 but plans to stay on as an advisor until early August. Mehrotra plans to divide his time between Micron headquarters in Boise, Idaho and Micron's Silicon Valley offices in Milpitas, California, a few blocks from SanDisk headquarters.

  • LaCie Announces 2big Dock: 2-Bay TB3 DAS with Card Reader, USB-A and DisplayPort (AnandTech)

    LaCie this week has taken the wraps off of the latest member of their family of DAS devices, the 2big Dock. The newly revealed dock is their first Thunderbolt 3/USB-C-enabled dock, offering the latest in connectivity for laptops and PCs. Operating as both a DAS and a TB3/USB-C hub, the 2big Dock integrates two high-performance hard drives while offering a card reader, a USB 3.0 Type-A port, and a DisplayPort (1.2). The 2big Dock offers up to 20 TB capacity with a sequential read/write speed of up to 440 MB/s.

    Like their prior Thunderbolt 2 docks, LaCie is aiming to fully leverage the capabilities and intended use cases for Thunderbolt-equipped laptops. As discussed multiple times, modern high-end laptops are so thin that it in many cases it is physically impossible (or very complicated) to install full-sized USB Type-A or DisplayPort headers on them and sometimes there is no space for memory card readers in the chassis (this is the case with Apple’s MacBook and MacBook Pro, HP’s Spectre and some other), which means that many people need docking stations to fulfill their connectivity needs.

    LaCie is a well-known name in the DAS business, however prior to now they've never done anything approaching a dock. So as you'd expect for a company whose core strength is in the storage business, the company has opted to build an entry-level DAS that also doubles as a Thunderbolt 3 dock. All-told, the 2big Dock offers card reader supporting SD and CompactFlash cards, a DisplayPort, a USB 3.0 Type-A port, and a USB 3.0 Type-C port with power delivery, while allowing the Dock to be used with both Thunderbolt 3 and pure USB-C host devices.

    LaCie is going to offer three versions of the 2big Dock DAS: with 12 TB, 16 TB and 20 TB capacities, all based on the Seagate IronWolf Pro enterprise-class drives for NAS. The DAS fully supports RAID 1 and RAID 0 capabilities for two HDDs — so owners can ensure either maximum reliability for their data (by mirroring them), or double their sequential read/write speeds up to ~440 MB/s (by striping them). LaCie does not disclose the exact controller it uses to enable hardware RAID functionality, but it is logical to assume that it is the ASMedia ASM1092R chip, which has two device ports and one host SATA port (and which was used in the previous-gen 2big DAS). As for controllers for the docking station, the manufacturer also remains tight-lipped and we do not know what kind of bridges are used for PCIe and SATA bridging, PCIe and USB bridging, or the card reader.

    Cables Included Thunderbolt 3 40Gb/s USB-C to USB-C cable
    USB-A to USB-C (5 Gbps) cable
    Software LaCie RAID Manager
    Price (MSRP) unknown unknown unknown

    Just like many other Thunderbolt 3 devices, the 2big Dock has two TB3 headers in a bid to daisy chain other TB3 devices, such as displays or special-purpose hardware. The 2big Dock DAS is also compatible with the previous-gen computers featuring Thunderbolt 2 ports (e.g., Apple’s Mac Pro and MacBook Pro) via a special adapter from Apple.

    The LaCie 2big Dock will be available this summer and will be covered by the company’s five-year warranty. Pricing is not announced, but since we are talking about a dual-bay DAS, it is not going to be astronomical. At least, expect the 20 TB version to be considerably more affordable than the 6big 24 TB ($3000).

  • Apple voudrait étendre Apple Pay à des transactions entre particuliers (MacBidouille)

    Recode rapporte qu'Apple étudie l'opportunité d'étendre le service Apple Pay à des transactions entre particuliers, et donc sans autres terminaux que deux iPhone.
    Il s'agirait donc dans ce contexte de concurrencer PayPal.

    Au niveau du volume de transactions, cela représenterait un énorme potentiel supplémentaire pour Apple, surtout que ce système devrait aussi permettre de payer des achats en ligne avec une authentification qui n'a pas encore été prise en défaut jusqu'à maintenant.

    A ce rythme, il ne serait pas surprenant qu'Apple lance une filiale bancaire d'ici la fin de la décennie et n'en profite pour se débarrasser d'intermédiaires comme Visa ou American Express qui n'auront plus d'intérêt.

  • Razer Announces The Lancehead Gaming Mice (AnandTech)

    Today Razer is launching a pair of gaming mice into their lineup. The Razer Lancehead Wireless Gaming Mouse, and the Razer Lancehead Tournament Edition are the two new models, and perhaps just as interesting is that they are also announcing a new version of their configuration software, dubbed Razer Synapse Pro, which is currently in beta. Both of the new mice feature an ambidextrous body, which should please those who prefer using the mouse with their left hand, and of course both mice support Razer's Chroma lighting.

    First up is the Lancehead Wireless Gaming Mouse. Wireless mice have come a long way, but they can still have issues in a group environment due to interference on the frequencies the radios operate at. This has been an ongoing issue since the dawn of time, and there are various methods to combat this. Razer is announcing a new technology in their repertoire to try to assist with these issues, and they are calling it Adaptive Frequency Technology (AFT). None of this is new science of course, since frequency hopping is par for the course, but Razer is advertising their AFT should help with latency by choosing the strongest interference-free channel when it starts, and only hopping when necessary. There’s nothing really unique about doing this, but with good error correction it should help. Razer is claiming that it outperforms every other wireless gaming mouse. Frankly it would be nice to see some of these devices move off of the extremely crowded 2.4 GHz frequency altogether, and with the relatively short distance from a mouse to a PC, it’s strange that they stick with the 2.4 GHz band.

    In addition to the wireless component, the Lancehead comes with a 16,000 DPI sensor with 210 inches-per-second tracking and it can handle up to 50 G of acceleration. It also features mechanical mouse switches that Razer co-developed with Omron, and Razer is claiming lower latency on the clicks, as well as up to 50 million clicks of durability.

    The second mouse is similar to the first, but ditches the wireless connection for a USB cable. The Razer Lancehead Tournament Edition also supports up to 450 inches-per-second of speed, and the same 16,000 DPI and 50 G acceleration as the wireless model.

    Razer is also announcing the new Razer Synapse Pro software, which will be released soon. The Lancehead owners will be the first to get a chance to use the new software. Synapse Pro supports both cloud and on-device storage for mouse settings, which is a welcome change from the existing software, which requires an online account to sync the mouse settings, and do most of the other configuration. The new Synapse Pro will allow a user to access their device profile on any computer without requiring an internet connection. Finally.

    Razer will be offering the new mice for pre-order now, with shipments of the Tournament Edition starting now with worldwide availability in April/May, and the Lancehead Wireless Gaming Mouse will be available in the May/June timeframe. Pricing starts at $79.99 USD for the wired version, and $139.99 for the wireless model.

  • Skylake-SP Xeon List Published: Moving from E7/E5 Naming to Xeon Gold and Xeon Platinum (AnandTech)

    Presumably by accident, Intel this week has published a list of its upcoming processors that belong to the soon-to-launch Skylake Xeon families. The names were published by Intel in a PCN, or Product Change Notification, which makes it likely that this was an accidental disclosure.

    In the PCN, it details that LGA3647 CPUs (which covers Xeon Phi processors and the upcoming Skylake Xeons) will have an arrow indicating which way processors should be oriented in the socket. It seems like an arbitrary PCN, just printing an arrow on a heat spreader, which makes this published list somewhat unexpected. But these names show the key parts of the Purley platforms for servers.

    One of the poorly kept secrets in the industry over the last few weeks is that Intel is changing the nomenclature of its Xeon CPUs going forward. This will be a difficult change to explain, given that users are so familiar with the previous naming system, and the translation between old and new is not a simple one-to-one mapping. Skylake-SP thus introduces the new Xeon Gold and Xeon Platinum lineups for different markets of servers. We expect all these CPUs to be on LGA3647, given that the PCN seems to suggest that this singular print marking on the heatspreader was not on this socket design before.

    Unfortunately, the published list does not have full CPU information, but we do get names and frequencies of 34 Skylake-SP processors (see details below) that will belong to the Xeon Gold and Xeon Platinum lineups, as well as the fact that these processors are designated with the H0 stepping. We might not see all these processors at launch (which at this time has still not officially been announced), and we expect Intel to expand the Xeon Gold/Platinum family with new models over the several quarters following the launch.

    Based on the document, the initial Xeon Gold family will consist of 20 processors featuring 5000- and 6000-series model numbers. The Xeon Platinum lineup will feature 14 chips belonging to the 8000-series.

    Xeon Gold 6126 2.6 GHz CD8067303405900 SR3B3
    Xeon Gold 5122 3.6 GHz CD8067303330702 SR3AT

    Most importantly, the PCN confirms that Intel is about to scrap its Xeon E5/E7 naming nomenclature for something different with the introduction of the Skylake-SP/EP processors. Instead of E5 and E7, Intel will call its CPUs for 2P and 4P/MP servers Xeon Gold and Xeon Platinum. Moreover, the feature-sets of chips aimed at different kinds of servers will also be different, just like today. The upcoming Xeon Gold CPUs will work in 2P configurations and will thus replace the existing Xeon E5-series. Meanwhile, it is logical to assume then the replacement for the Xeon E7 will be called the Xeon Platinum, and apart from higher maximum core count will also support various additional capabilities, including RAS features. We suspect that there will be more names than Gold and Platinum coming to market to cover other aspects of Intel's product stack.

    In the processor stack above, we also get T and M processors in the mix. T processors have historically been lower power processors, and this is likely still the case given that the T processors have lower frequencies than most of the rest of the CPUs. Some CPUs, like the Xeon Gold 6130 and 6130T, are at 2.0 GHz for both: this is likely relating to different turbo frequencies, but also the T product is binned for lower power. The M processors are somewhat of a mystery, as we've never had M on a processor before, except in mobile. Speculating a bit on our part, this could be a reference to MCDRAM, which is a feature we see on Xeon Phi processors. Although to be clear, we have nothing to suggest that Intel will be including MCDRAM on these parts, as the Xeon CPU die itself may be big and the MCDRAM silicon is also relatively sizeable. We suspect that the M processors will have a given feature or features in common, which might come at an extra expense in the final price tag.

    In previous generations, Intel typically creates three different core designs for it's latest Xeons: a low core count (LCC), medium/high core count (MCC/HCC, depending on the document), and an extreme core count (XCC) version. The XCC version has the highest amount of cores, the most cache, and costs the most, but typically the per-core frequency is low. Intel sometimes offers the XCC in a small core count configuration, but with a large cache, and something like the Xeon Platinum 8156 at 3.6 GHz most likely fits that description. One of the things that should seem obvious is that the naming of each processor is not linear with clock frequency. For example, the Gold 6150 runs at 2.7 GHz base, but the Gold 6152 runs at 2.1 GHz base. Using that fourth digit extensively means that we hope Intel has a strong and obvious way to describe which part of the CPU names mean specific things. At this point it is hard to see a specific pattern, given we do not know core counts.

    Disclaimer: There's a significant amount of information in the ecosystem about the upcoming Skylake-SP platform, mostly from leaks that we can't personally confirm. So while we appreciate there is information out there, we've kept this analysis specifically to what is confirmed or could be inferred, as per AnandTech policy.

  • Le Hackintosh s'affiche de plus en plus, décomplexé (MacBidouille)

    Il y a de très nombreuses années de cela, nous avions eu l'idée de publier une vidéo d'un des premiers Hackintosh jamais montré dans le monde Mac, un portable PC démarrant sous la l'une des premières beta d'OS X X86.
    Cela nous avait valu un magnifique courrier des avocats d'Apple exigeant que nous retirions cette vidéo sur le champ.

    Depuis de l'eau a coulé sous les ponts et les Hackintosh ont droit sinon à la bénédiction d'Apple, tout du moins à un grand laxisme à leur sujet.
    Les choses se sont accélérées depuis la sortie des Mac Pro 2012 et le manque de vigueur d'Apple dans le monde du marché des ordinateurs de bureau. Maintenant, certains sites sont uniquement orienté là dessus et d'autres plus généralistes comme 9to5Mac n'hésitent pas à afficher leurs dernières créations. C'est ce que ces derniers viennent encore de faire en présentant leur dernière création, une machine utilisant entre autre une Geforce GTX 080 Ti.
    En voici une présentation en vidéo.

    A peu de choses près tout fonctionne sauf iMessage, la 4K à 60Hz et le Thunderbolt 3 qui n'a plus beaucoup d'intérêt si l'on a une tour.

    Comme vous pouvez le voir, il faut un Mac Pro 12 coeurs pour faire mieux, et seulement en multi CPU, le tout pour une fraction de son prix.

  • Celebrating AnandTech’s 20th Anniversary: 1997 - 2017 (AnandTech)

    This morning we’re celebrating a rather special occasion over here at AnandTech: our 20th anniversary. Though in a lot of ways it seems like the years have gone by in a flash, the calendar doesn’t lie: it means we’ve now been doing this for two decades, starting from a quaint CPU review in 1997 and branching out to oh so much more by 2017.

    For the start of AnandTech’s 21st year in the technology news business, I’d like to commemorate the occasion with a look back at what we’ve done, a brief look forward at where we’re going next, and finally, thank the many readers and groups out there who have made it possible. I’m also happy to announce that we’re launching our largest hardware giveaway ever: over the next 20 days we'll be giving away hardware to celebrate our 20 years in business. So you'll want to check back daily for new giveaways.

  • AT20 Giveaway Day 1: AMD Ryzen CPUs & Radeon RX 570 Video Cards (AnandTech)

    For some of our past anniversaries we’ve done hardware giveaways, and for our 20th anniversary I wanted to do the best giveaway yet. It only seemed fitting that as a thank you to the readers that have supported us over the last two decades, that we try to give something back to you.

    I set out with a goal to do 20 days of giveaways, one for each year of AnandTech’s existence. To do so, myself, the other editors, and the sales team reached out to our friends at hardware vendors across the globe to line up hardware for our greatest giveaway ever. The results exceeded even my wildest expectations.

    31 vendors have donated hardware for the AnandTech 20th anniversary giveaway, smashing even my most optimistic goals. We still haven’t finished adding up the value of all of the prizes, but it’s tens of thousands of dollars. It’s honestly almost more than we could handle, if not for the hard work of the Purch community team in helping out to organize all of this.

    So a big thank you goes out to our friends at Intel, AMD, HTC, NVIDIA, Seasonic, ARM, Asus, and more, for providing us with so many prizes to give out to you guys. I knew we had a lot of friends, but it’s only after you ask for free hardware to give to random readers that you realize just how many friends you have. And similarly, how these companies are eager to make a good impression with you.

    Starting today and running through May 23rd, we’re doing 20 days of giveaways. We have CPUs, motherboards, phones, tablets, video cards, cases, power supplies, laptops, and even some bona fide swag to give away. Each giveaway is only open for 48 hours, so you’re going to want to check in each and every weekday to enter that day’s giveaway(s). Many will enter, not as many will win, but with the number of prizes we have available the odds may be more in your favor than you think.

    However for our many international readers, I need to apologize. We’ve not been able to do international giveaways, and the 20th anniversary giveaway is no different. AnandTech/Purch is too big to do a clandestine giveaway, and that means we need to follow all of the relevant local laws on giveaways. And, as it turns out, there are a lot of countries out there who either dislike giveaways or require that someone in their country wins a giveaway in order for it to be offered there. As a result, we’re only able to open these giveaways to residents of the United States. I’m genuinely sorry we can’t offer anything outside of the United States, but I hope you can understand.

    Anyhow, for our first giveaway I thought it was only appropriate that we go full-circle and start back where AnandTech itself started: AMD.

    The AnandTech 20th Anniversary - AMD Giveaway

    Altogether, AMD has given us 6 prizes to hand out: a Ryzen 7 1800X, a Ryzen 5 1600X, or one of four Radeon RX 570 video cards.

    AMD Ryzen 7 1800X & Ryzen 5 1600X

    The Ryzen 7 1800X and Ryzen 5 1600X are AMD’s top 8-core and 6-core processors respectively, forming the backbone of their new Ryzen CPU family. Marking a rather dramatic turnaround for the company in the CPU space, the Zen architecture has massively improved AMD’s IPC and overall single-threaded performance, changing the competitive landscape of the CPU space almost overnight.


    AMD Ryzen Prizes
    L3 TDP
    Ryzen 7 1800X 8/16 3.6/4.0 16 MB 95 W
    Ryzen 5 1600X 6/12 3.6/4.0 16 MB 95 W

    As our own Ian Cutress put it in his Ryzen 5 review: “for anyone wanting to do intense CPU work, the Ryzen gets a nod here. Twelve threads are hard to miss at this price point”. AMD isn’t able to exceed Intel’s single-threaded performance, but the release of a powerful processor with so many cores has served to make the x86 market a lot more interesting.

    AMD Radeon RX 570

    Meanwhile AMD also sent over 4 different Radeon RX 570 cards, each from one of their different board partners: Gigabyte, MSI, ASUS, and PowerColor.

    • Gigabyte AORUS Radeon RX 570
    • MSI Radeon RX 570 Gaming X
    • ASUS ROG Strix Radeon RX 570
    • PowerColor Red Devil Radeon RX 570

    The Radeon RX 570 is AMD’s recently-launched SKU for mainstream 1080p gaming. The cards all offer 32 CUs, 4GB of VRAM, and clockspeeds of 1244MHz or better.

    All of the cards are open air type coolers, with 3 of the cards using a dual fan configuration, while PowerColor’s card takes it up a notch with three fans.

    In our review of the RX 570, we found that the cards put up good numbers for a 1080p card, and should be able to handle 1080p gaming with few-if-any compromises, making it the cornerstone of an excellent gaming PC.

  • Apple annonce avoir deux millions d'utilisateurs de Final Cut Pro X (MacBidouille)

    A l'occasion du NAB, Apple a annoncé que Final Cut Pro X avait franchi le cap des deux millions d'utilisateurs.
    Le rythme d'adoption serait en hausse et il aura fallu moins de temps pour passer de 1 à deux millions que pour convaincre le premier million d'utilisateurs.
    Lors de sa sortie il y a 5 ans et demi, Final Cut Pro X avait rencontré un accueil glacial pour ne pas dire hostile. Non seulement le logiciel changeait profondément les habitudes mais aussi parce que, comme souvent chez Apple, il est arrivé avec nombre de manques qu'il aura fallu du temps et des mises à jour pour les combler.
    Maintenant, elle est arrivé à maturité et permet à Apple, une fois de plus dans une courte période, de rappeler qu'elle s'intéresse aux professionnels.
    A coup sûr, un nouveau Mac Pro évolutif aidera le marché des professionnels de l'image à poursuivre leur aventure sous ce logiciel et même en convaincre d'autres de l'adopter.

  • NVIDIA Releases 381.89 WHQL Driver (AnandTech)

    I wouldn’t claim NVIDIA is keeping up the pressure with their driver releases, but they are keeping a good pace releasing their second driver update this month. The beginning of this month saw the initial Release 381 driver branch published with 381.65, which added support for the GeForce GTX Titan Xp, Windows 10 Creators Update, Dolby Atmos, and DTX:X enabling up to 5.1.2 speaker setups. Now NVIDIA is back for their first point update with 381.89.

    The latest driver release from NVIDIA contains several small fixes, including fixes for Sniper Elite 3 crashing, a BSOD issue for notebooks running eDP panels, and a BSOD issue with the GeForce GTX 1060 coming out of sleep mode. NVIDIA also notes that they have rolled out a fix for a bug introduced in an earlier driver release that unnecessarily raised idle GPU voltages, which means some cards should see lower idle temperature and noise levels.

    Relative to the typical number of games added with drivers, we have a decent amount of supported games in the 381.89 release.  This includes the upcoming PC exclusive Warhammer 40,000: Dawn of War III and Blizzard’s Heroes of the Storm 2.0 update. Scooting over to VR, NVIDIA has also included optimizations for Batman: Arkham VR, Rick and Morty: Virtual Rick-ality, and Wilson’s Heart.

    Anyone interested can download the updated drivers through GeForce Experience or on the NVIDIA driver download page. More information on this update and further issues can be found in the 381.89 release notes.

  • Un débat autour des PC infectés par des logiciels espions de la NSA (MacBidouille)

    Les révélations sur les outils de piratage de la NSA ont soulevé nombre d'interrogations sur le nombre de machines infectées et les personnes ciblées.
    C'est même aujourd'hui la cause d'un débat entre Microsoft et de nombreux spécialistes. Les deux parties se disputent sur le nombre de machines infectées sur la toile par un de ces dangereux chevaux de Troie. Ce logiciel malveillant est particulièrement complexe et difficile à détecter. En effet, il n'écrit rien sur la machine ciblée et reste seulement résident dans la RAM. En cas de redémarrage il est supprimé. Il est pourtant capable d'envoyer des données de manière très furtive à ceux qui l'ont installé.
    Selon les chercheurs et les sources, il y aurait entre 10000 et plusieurs dizaines de milliers (voire 120000) de PC actuellement infectés, chose que Microsoft tend à minimiser.

    Il serait difficile de scanner toutes les machines du monde pour le savoir. Toutefois, comme le rapporte ARS Technica, un chercheur en sécurité a étudié à fond ce logiciel malveillant et trouvé le moyen de le désactiver à distance en envoyant une simple commande antagoniste de celle qui a permis de l'installer.

    Ce n'est qu'une péripétie dans le cadre de ces révélations, le vrai et profond danger se concrétisera le jour où des pirates trouveront le moyen de modifier les outils de la NSA pour les faire diverger de leur utilisation primitive et les exploiter pour des activités criminelles.

  • ARM lance un processeur de traitement de signal destiné à l'assistance de conduite (MacBidouille)

    Toute l'industrie électronique a maintenant les yeux braqués vers le marché automobile. C'est le nouveau vecteur de croissance destiné à prendre le relais de celui des smartphones qui lui-même a pris le relais des ordinateurs.
    ARM a dans ce domaine annoncé le Mali-C71.

    Ce processeur d'image est capable de gérer 4 caméras en temps réel et jusqu'à 16 flux vidéo.

    Les signaux qu'il reçoit sont traités en temps réel et améliorés pour prendre en compte la luminosité et les conditions climatiques afin d'améliorer l'image, supprimer les artéfacts et offrir une vision aussi bonne que possible, meilleure même que la vision humaine dans certaines conditions.

    Le produit a été conçu dès le départ comme aide à la conduite ou composant de la chaîne matérielle destinée à créer des voitures autonomes. Il est d'ailleurs doté de 300 circuits spécifiquement dédiés à détecter un éventuel défaut de fonctionnement, chose que l'on voit plus souvent aujourd'hui en aéronautique.

    ARM le destine donc à gérer les caméras des véhicules mais aussi à proposer des systèmes de détection de piétons ou à remplacer les rétroviseurs par des caméras.

  • Une rumeur annonce un significatif retard pour l'iPhone OLED (MacBidouille)

    Ming-Chi Kuo, spécialiste Apple chez KGI, prédit aujourd'hui qu'Apple devra repousser significativement la commercialisation de son iPhone OLED.
    La société pourrait ne démarrer la production qu'entre octobre et novembre au lieu de août-septembre.
    La faute en reviendrait aux nombreuses nouveautés qu'Apple veut intégrer dans cet appareil et qui ont nécessité des développement spécifiques et pointus que les sous-traitants ont du mal à intégrer dans leurs procédés de fabrication.
    Il met dans ce sac de choses problématiques l'écran OLED spécifique, le processeur gravé en 10nm, le nouveau 3D Touch et la caméra à reconnaissance faciale 3D.

    Ce ne sont bien entendu que des rumeurs et elles sont donc à prendre comme telles.

    [MàJ] Nikkei a publié des informations concordantes annonçant que l'iPhone OLED n'arriverait dans le commerce qu'en octobre ou novembre.
    On ignore toutefois si les sources sont différentes, ce qui ajouterait à la rumeur, ou identiques, ce qui ne changerait rien.

  • AMD Announces Radeon Pro Duo (Polaris) - Double Polaris for Content Creation (AnandTech)

    Back in 2016 AMD launched the Radeon Pro Duo, an interesting take on a semi-pro workstation card. As a dual-GPU Fiji card wasn’t going to be viable for the consumer market, AMD instead focused their attention on developing such a card for the professional content creation market, where the lack of VRAM would be less of an issue and the second GPU more of an asset. The resulting card was best geared for a niche market, but none the less an important one for the company.

    Until now, I hadn’t seen any real statistics on how the Radeon Pro Duo was doing in the market or if AMD would follow-up on it with newer products. Now at the 2017 NAB Show we have our answer, as AMD has announced their second Radeon Pro Duo. This time powered by a pair of the company’s Polaris 10 GPUs, the latest Radeon Pro Duo is aimed at roughly the same market as the original, but with all of the improvements that Polaris has brought the consumer market in the past year.

    Even though it goes after the same market as the last Pro Duo, the new Polaris-based Pro Duo is a much different card in a number of important ways, virtually all of which have to do with the differences in features and design between the previous Fiji GPU and the newer Polaris 10 GPU. Fiji was a high-end GPU that had to be reined in a bit to fit on a dual GPU card – and even then AMD needed a closed loop liquid cooler – whereas the Polaris 10 GPUs that go into the modern incarnation have a much more workable TDP from the start. Coupled with that, Polaris 10 doesn’t have the fixed VRAM capacity of Fiji, which means AMD can significantly increase the total VRAM. As a result, the new Pro Duo strikes a very different balance than the old card.

    By the numbers then, the Polaris-based Radeon Pro Duo is actually slower than the older Fiji version. It has a clockspeed advantage, but this isn’t enough to overcome Fiji’s total stream processor advantage. All told, at peak rates the new Pro duo is rated for 11.45 TFLOPs of FP32, while the Fiji version was rated for 16.38 TFLOPs. In practice however I don’t expect that the gap is quite so large, as Fiji would need to throttle more often, and Polaris enjoys at least a small architectural advantage.

    What the new Pro Duo loses in throughput it more than picks up in VRAM. With each Polaris 10 GPU sporting a 256-bit GDDR5 memory bus, AMD has outfit each GPU with 16GB of VRAM, quadrupling their VRAM capacity. AMD’s photos don’t show the bare PCB, but I believe it to be a safe bet that AMD is running 8Gb modules in clamshell mode, meaning the board is truly maxed out. AMD argued that the smaller VRAM capacity of the Fiji based card was not a major liability last year, and while there’s admittedly no reason not to fully equip a Polaris 10 card since the company is back to GDDR5, I do think it’s an important step in making the new card more flexible.

    The other big change here is that the TBP has come down significantly, from 350W to 250W. Fiji was powerful, but it was also power-hungry, necessitating the original card’s closed loop liquid cooler. The Polaris Pro Duo, on the other hand, can get away with a simple blower. In fact this is the first time we’ve seen a blower-type dual GPU card from AMD in many years. And though an uncommon choice for a dual GPU card, it makes a great deal of sense given the card’s professional workstation market, as blowers are expected there, and the Radeon WX cards are already similarly equipped.

    Under the hood – and particularly catering to the NAB crowd – the move to Polaris means that AMD can now support DisplayPort 1.4 and HDMI 2.0b a significant step up from DP 1.2 and HDMI 1.4b on the previous card. Besides natively supporting contemporary HDMI and HDR displays, this means that AMD can now also drive 8K monitors using a dual-cable setup. All told, the new card comes with 3x DP 1.4 ports and a single HDMI 2.0b port, and can drive all 4 ports at once.

    With their new card AMD will be going after the same content creation niche as the old card, which means a mix of video production and VR. The latter in particular is still a growth market for AMD, and the card’s two GPUs means that developers can take advantage of AMD’s Affinity Multi-GPU technology with only a single card. Though to be sure, AMD is positioning and promoting this more like their Radeon WX professional cards, so like its predecessor, the new card will get AMD’s pro drivers and limited official support for the major CAD, CAM, and other engineering software packages.

    Wrapping things up, the Polaris-based Radeon Pro Duo will be launching next month at $999. For the moment at least, this puts it at the head of AMD’s professional cards, at least until a WX Vega card finally shows up.

Aussi, MultideskOS n'utilise plus de programmation conditionnelle,
contrairement aux autres. Dans la pluspart des cas, fini les IF, ELSE,
ENDIF. Exemple : PutButton LeftReach [Vies = Vies - 1] En clair, dès que
l'on relâchera le bouton gauche de la souris sur ce bouton, le nombre de
vies diminuera de 1. On peut ainsi appeler des variables, des fonctions,
etc.. Ceci évite les traditionels : "IF (ButtonName = Button1) Then" On
se retrouve avec un programme ne faisant alors que quelques lignes. --
