    Anandtech: Assassin’s Speed: Eve Technology Reveals 27-Inch QHD Monitors With 240Hz V

    Eve Technology is known primarily for its crowd-developed 2-in-1 Eve V notebook introduced a couple of years ago. But this week the company introduced its first crowd-developed displays. The Spectrum monitors designed for gamers also happen use some of the industry’s first QHD (2560x1440) IPS panels that feature a 240 Hz refresh rate.
    Eve’s Spectrum lineup of gaming displays includes three 27-inch models. The most basic model has a 2560x1440 resolution, 450 nits maximum brightness, and a 165 Hz refresh rate. The ‘fastest’ 240Hz SKU has a 2560x1440 resolution and 750 nits peak brightness. The most advanced version features a 3840x2160 resolution, 750 nits max brightness, and a 144 Hz refresh rate. All the monitors rely on an 8-bit + AFRC IPS panel from LG, which is equipped with a proprietary backlighting as well as a special polarizer that enables the LCDs to display a 98% of the DCI-P3 color gamut.
    All the monitors support VESA’s Adaptive-Sync variable refresh rate technology and are AMD FreeSync Premium Pro as well as NVIDIA G-Sync Compatible certified. Also, the displays support HDR10 and are VESA DisplayHDR 400 or 600 certified, depending on the model.
    Connectivity is one of the strong sides of Eve’s Spectrum monitors. All models feature one DisplayPort input and output, one HDMI input, and two USB-C inputs with one supporting a 100 W Power Delivery. In addition, the LCDs feature a triple-port USB 3.1 Gen 2 Type-A hub and a headphone jack.
    It is noteworthy that while the Eve Spectrum displays are aimed at gamers, their minimalistic design does not ‘scream’ about their gaming nature. Furthermore, the monitors do not come with a stand; if you aren't bringing your own, then that will cost an additional $99.

    Anandtech: Quick Notes: Navi Refresh and RDNA2 Both In 2020, According to AMD

    As part of today’s FY2019 earnings call, AMD CEO Dr. Lisa Su had a few words to say about AMD’s future GPU plans – an unexpected nugget of information since we weren’t expecting AMD to reveal anything further at this time.
    In short, for this year AMD is planning on both Navi product refreshes as well as parts based on the forthcoming RDNA 2 GPU architecture. To quote Lisa Su:
    In 2019, we launched our new architecture in GPUs, it's the RDNA architecture, and that was the Navi based products. You should expect that those will be refreshed in 2020 - and we'll have a next generation RDNA architecture that will be part of our 2020 lineup. So we're pretty excited about that, and we'll talk more about that at our financial analyst day. On the data centre GPU side, you should also expect that we'll have some new products in the second half of this year.
    All told, it looks like AMD is setting themselves up for a Vega-like release process, launching new silicon to replace their oldest existing silicon, and minting new products based on existing and/or modestly revised silicon for other parts of their product stack. This would be very similar to what AMD did in 2017, where the company launched Vega at the high-end, and refreshed the rest of their lineup with the Polaris based Radeon RX 500 series.

    AMD's GPU Roadmap As Of July 2019
    But as always, the devil is in the details. And for that, we’ll have to stay tuned for AMD’s financial analyst day in March.

    Anandtech: Crucial’s 32 GB UDIMMs and SODIMMs Available: DDR4-2666 & DDR4-3200

    In the summer of 2019, Crucial was among the first brands to demonstrate 32 GB unbuffered memory modules, which were based on Micron’s 16 Gb DDR4 chips. Now after a bit of a wait, those 32 GB UDIMMs as well as 32 GB SO-DIMMs have finally hit the retail market.
    Crucial’s 32 GB unbuffered DIMMs and SO-DIMMs are rated for DDR4-2666 with CL19 at 1.2 V and DDR4-3200 with CL22 at 1.2 V operation. The modules are not equipped with any heat spreader and since they operate in JEDEC-standard modes, they are compatible with a wide variety of PCs that can support 32 GB UDIMMs in general.
    At present, Crucial’s 32 GB UDIMMs and SO-DIMMs are available as 64 GB dual-channel memory kits priced at around $330 at the company’s website. Interestingly, the faster DDR4-3200 kits are only $2 more expensive than the slower DDR4-2666 kits. Meanwhile, expects Crucial’s 64 GB dual-channel DDR4-2666 SO-DIMM kit to arrive on February 3, 2020.
    It is unclear why Crucial did not start selling its 32 GB UDIMMs and SO-DIMMs to general public earlier, as there are a number of brands that have been offering competing 32 GB UDIMMs using the same Micron chips for months now. In any case, Crucial’s 32 GB DIMMs are finally available.

    Anandtech: Matrox Unveils D-Series Graphics Cards with NVIDIA Quadro GPUs

    Matrox Graphics is one of the oldest graphics card manufacturers still in business today. It started to make video cards in 1978, several years before ATI, and 15 years before NVIDIA. While the company's own internal GPU development efforts petered early this century, the company has continued on as a specialist card maker, using other vendors' GPUs to make special-purpose multi-monitor solutions. Since 2014 the company has been using AMD’s GPUs for its boards, and earlier this month the company inked a similar agreement with NVIDIA. This week, Matrox launched its first NVIDIA-based graphics cards.
    The Matrox D-series family of multi-display graphics cards based on a custom-built NVIDIA Quadro embedded GPU and carries 4 GB of GDDR5 memory as well as four DisplayPort 1.4 (D1480) or four HDMI 2.0 (D1450) outputs. The D1450 supports four monitors, with a maximum resolution of up to 4096x2160@60Hz, whereas the D1480 adapter supports four monitors with resolujtions up to 5120×3200@60Hz. The card consumes 47 W and only uses power supplied to it through the PCIe x16 slot.
    For video wall applications used in aerospace, military, pro A/V, digital signage, security, and industries, four of Matrox D-series boards can be combined in a single system via board-to-board framelock cables, driving up to 16 displays using one PC. In addition, the cards can further be augmented with Matrox's QuadHead2Go multi-display controllers to drive up to 64 Full-HD screens from a single PC. It is also possible to pair D-series cards with Matrox Mura IPX capture and IP encode/decode boards for applications that need those capabilities.
    Matrox does not disclose which GPU it uses for the D-series video cards, but it claims that the ‘custom-built’ NVIDIA Quadro GPU is compatible with DirectX 12, OpenCL 1.2 and OpenGL 4.5, which points to one of NVIDIA’s latest architecture (e.g., Pascal, Turing).
    Matrox’s D1450 and D1480 graphics cards will be available sometimes in the second quarter. Their exact pricing is unknown, but expect to see Matrox to charge a premium for their specialized products.

    Anandtech: Enmotus MiDrive: Rethinking SLC Caching For QLC SSDs

    For consumer storage, CES 2020 brought a new wave of competition for PCIe 4.0 SSDs and promise of faster portable SSDs, but the most intriguing product demo was from Enmotus. They are planning a profound change to how consumer SSDs work, ditching drive-managed SLC caching in favor of host-managed tiered storage.
    Enmotus is a well-established provider of storage management software. Their most familiar product to consumers is probably FuzeDrive, a limited edition of which is bundled with recent generations of AMD motherboards as AMD StoreMI. This serves as AMD's answer to Intel's Smart Response Technology (SRT) and Optane Memory storage caching systems. Enmotus also has enterprise-oriented products in the same vein. Their new MiDrive technology builds on their existing tiering software to manage a combination of SLC and QLC NAND on a single consumer SSD.
    Caching and Tiering Challenges

    All software-driven caching or tiering solutions tend to have limited consumer appeal due to the complexity of setting up the system. At least two physical drives are required, and the OS needs to load an extra driver to manage data placement. Any compatibility issue or other glitch can easily render a PC unbootable, and data recovery isn't as straightforward as for a single drive. These hurdles don't scare off enthusiasts and power users, but PC OEMs aren't eager to market and support these configurations. But without some form of caching or tiering, consumer SSDs would be limited to the raw performance of TLC or QLC NAND. SLC caching managed transparently by the SSD's firmware has been adopted by almost all consumer SSDs in order to improve burst performance, and it has proven to be very effective for consumer workloads. The fundamental limitation of this strategy is that the SSD must work with limited information about the nature and purpose of the user data it is reading and writing.
    Most SSDs rely on fairly simple procedures for managing their SLC caches: sending all writes to the cache unless it's full, and using idle time to fold data from SLC into more compact TLC representation, freeing up cache space for future bursts of writes. There are still some choices to be made in implementing SLC caching for consumer SSDs: whether to use a fixed-size cache or dynamically sized, and whether to stall when the cache fills up or divert writes straight to TLC/QLC. As QLC drives become more common, we're also seeing drives that prefer to keep data in the SLC cache long-term until the drive starts to fill up, so that the cache can help with read performance in addition to write performance.
    Enmotus FuzeDrive manual data placement controls
    Host-managed caching or tiering opens the door to more intelligent management of data placement, since the host OS has better information: about which chunks of data belong to what file, and about the processes and users that interact with those files. It is easier for the host OS to accurately track the history of access patterns for hot vs. cold files. It is also possible to expose manual control of data placement directly to the user.
    Two Drives In One

    The Enmotus MiDrive technology allows one SSD to present the host with access to two separate pools of flash storage: QLC and SLC managed by the same SSD controller. To implement this, they have partnered with Phison to modify SSD controller firmware. For server products, a single NVMe SSD would expose two separate NVMe namespaces that Linux treats as different block devices. But for consumers, Enmotus has chosen to maximize backwards compatibility by having the MiDrive present itself as a single block device, with the first 32 or 64 GB initially mapped to SLC NAND and the rest of the drive mapped to QLC NAND. This makes it possible (and fast!) to install an OS to a MiDrive without needing any special Enmotus software or drivers. Once the Enmotus driver has been loaded, it takes over the management of data placement using vendor-specific commands that instruct the SSD to promote or demote ranges of Logical Block Addresses (LBAs) between the QLC and SLC pools of flash. (The initialization process for this tiering currently takes about a quarter of a second, because very little data needs to be moved until there's history indicating what should be in QLC vs SLC.)
    Enmotus MiDrive 800GB appearing as a single device
    This is a lot simpler for the host side than the strategy Intel uses for their Optane Memory H10, which is two separate PCIe devices on one M.2 card and requires special motherboard support to properly detect both halves before the caching software can even get involved. Enmotus is working to make MiDrive even simpler by having Microsoft distribute the Enmotus driver with Windows, so that a MiDrive will be automatically detected and managed by the Enmotus software without requiring any user intervention. For now, Windows will default to using its standard NVMe driver for a MiDrive, but that should change by the time products hit the shelves.
    Example of how MiDrive LBA allocation will change with use
    (for illustration purposes only, not based on real testing)
    Enmotus supports assigning data to SLC or QLC in 4MB chunks, which is probably the size of a single NAND flash erase block in SLC mode, and thus the smallest chunk size that can easily be remapped between the QLC and SLC portions of the drive without contributing to unnecessary write amplification. That 4MB block size means that a small file moved to SLC is likely to bring along other nearby files, which will often contain related data that may also benefit from being in SLC. It also means that large files can be partially resident in SLC and partially in QLC. Since this process doesn't change the logical block addresses a file occupies, Enmotus MiDrive doesn't need to change anything about how NTFS organizes data, and it doesn't need to behave like an advanced disk defragmenter that tries to move important data toward the beginning of the disk. The MiDrive software only needs to look up what LBAs are used by a file and tell the SSD whether to move that data to SLC or QLC blocks. The only side-effect visible to the rest of the OS is a change in the performance characteristics for accessing that part of the SSD.
    The SLC portion of an Enmotus MiDrive differs from a traditional SLC cache not only by being host-managed, but also in how the SSD treats it for wear leveling purposes. A typical SSD's SLC cache may have a static or dynamic size, but in either case when new write commands arrive the SSD will write the data to whatever NAND flash block is currently empty. When the cache is flushed, data from several SLC blocks will be rewritten in TLC or QLC mode to a different empty block, and the SLC blocks are then free to be erased and put back into the pool of available blocks. Managing just one pool of empty blocks means that the actual physical location of the SLC cache can move around over time, and a block that was last used as TLC might end up being used as SLC the next time data is written to it.
    By contrast, Enmotus MiDrive technology has the SSD track two entirely separate pools. When the drive is manufactured, the SLC portion is permanently allocated for the lifetime of the drive. Any physical NAND pages and blocks that are used as SLC will always be treated as SLC for the lifetime of the drive, and the same for the QLC portion. The two pools of flash are subject to completely independent wear leveling, even though SLC and QLC portions will exist side by side on each physical flash chip on the drive. This means that the QLC blocks will never be subjected to the short-term Program/Erase cycles of SLC cache filling and flushing. For the SLC blocks, the error correction can be tuned specifically to SLC usage, and that allows Enmotus to achieve around 30k Program/Erase cycles for the SLC portion of the drive (based on Micron QLC NAND). MiDrives will expose separate SMART indicators for the SLC and QLC portions of the drive, so monitoring software will need to be updated to properly interpret this information.
    In principle, it would be possible for either the SLC or QLC portion of the drive to be worn out prematurely, but in practice Enmotus is confident that their tiered storage management software will lead to longer overall drive lifespans than drive-managed SLC caching. Files that are known to be frequently modified will permanently reside on SLC and not be automatically flushed out to QLC during idle time. If the Enmotus software is smart enough, it will also be able to determine which files should skip the SLC and go straight to QLC until it becomes clear that a file is frequently accessed. For example, a file download coming into the machine over gigabit Ethernet will not initially need SLC performance because raw QLC can generally handle sequential writes at that speed (especially with no background SLC cache flushing to slow things down). And if that file is a movie which is infrequently accessed and only read sequentially, there's no reason for it to ever be promoted up to SLC. In general, the tiered storage management done by Enmotus should result in less data movement between SLC and QLC, rather than the increased write amplification that traditional SLC caching causes.
    Since the SLC portion of an Enmotus MiDrive is a slice carved out of regular QLC NAND, it cannot offer all the benefits of specialized low-latency SLC NAND like Samsung's Z-NAND or Kioxia/Toshiba XL-Flash. The SLC portion of a MiDrive won't be appreciably faster than the SLC cache of a traditional consumer SSD, but that performance will be more consistent and predictable when working with files that are kept entirely on the SLC portion of the drive.
    The Business Model

    Enmotus MiDrive is currently implemented as a combination of Windows driver software and custom SSD firmware for Phison NVMe controllers, but it does not require any custom hardware. This means that any vendor currently selling Phison E12 NVMe SSDs can make a MiDrive-based product by licensing and shipping Enmotus firmware. PC OEMs can adopt MiDrives by switching to drives with Enmotus firmware and ensuring that they either include the Enmotus drivers in their Windows images, or relying on them to be distributed through Windows Update. No motherboard firmware or hardware modifications are required, or any changes to the process of provisioning a machine and preparing it for delivery to the end user. Enmotus is engaging both with PC OEMs and vendors of retail SSDs, so we can expect pre-built systems with Enmotus MiDrive technology and and upgrade options usable on any Windows 10 PC that already supports standard M.2 NVMe SSDs. Enmotus is optimistic about uptake from PC OEMs, expecting MiDrive to get a much better reception than Intel's Optane H10 did.
    The basic MiDrive products will be fully automatic, with the Enmotus driver pre-installed or installed automatically when a MiDrive is detected. Data placement decisions will be completely behind-the-scenes. For enthusiasts, there will also be a premium tier similar to their current FuzeDrive software, which includes Windows Explorer shell integration so that individual files can be manually promoted or demoted, either permanently or for a limited period of time. Enmotus will also be providing a drive health monitoring tool that will include their estimate for how much extra drive lifetime has been won by using their tiering instead of ordinary SLC caching.
    Mockup of Enmotus MiDrive SSD health monitoring tool
    Enmotus expects SSDs with MiDrive technology to mostly use either 32GB or 64GB SLC portions and offer total capacities from about 400GB up to around 2TB, but the exact configurations will be determined by what their partners want to bring to market. Enmotus is also planning enthusiast-oriented solutions supporting RAID-0 style striping across multiple physical drives, and solutions for single-package BGA SSDs that go into small form factor and embedded devices.
    Enmotus MiDrive technology will add to the price of SSDs, but since we're talking about QLC storage that's only relative to the cheapest NVMe SSDs available, and the final sticker prices will still be competitive for consumer SSDs. In return for that, users should get better real-world performance and enough effective write endurance to justify a 5-year warranty. We're looking forward to testing out this technology later this year, even though it will further complicate our benchmarking process. Enmotus is already sampling to interested OEMs.

    Anandtech: Samsung Galaxy Book S Laptop with Snapdragon 8cx: Pre-Order at $999 from T

    Update 1/30/2020: The Samsung Galaxy Book S with Snapdragon 8cx is now available for pre-order, starting at $999. The device is set to be available from February 13th.

    Samsung has introduced its new always-connected PC based on Qualcomm’s Snapdragon platform and featuring Microsoft’s Windows 10 OS. This time around the company went with the Snapdragon 8cx SoC, a clamshell form-factor, and a 13.3-inch display, emphasizing that its Arm-powered computers compete against mainstream x86-based laptops in terms of performance and capabilities. Like other Snapdragon-based Windows machines, Samsung is aiming for long battery lifetimes here, with the new Galaxy Book S rated to work for up to 23 hours on a single charge.
    The Samsung Galaxy Book S is equipped with a 13.3-inch Full-HD LCD featuring a 10-point multi touch system and a 16:9 aspect ratio. By contrast, last year’s Galaxy Book2 used a 12-inch Super AMOLED display featuring a 2160×1440 resolution and a 3:2 aspect ratio. Unlike last year’s mobile PC, the new one is a laptop, not a convertible, so it cannot be used as a tablet. Considering that we are talking about an aluminum machine with a 13.3-inch display that weighs 0.96 kilograms, the clamshell form-factor makes more sense for mainstream users. Furthermore, the overall construction looks very solid.
    The new Galaxy Book S laptop is expected to be considerably faster than its predecessor as it is based on Qualcomm’s Snapdragon 8cx processor with eight general purpose cores (four Cortex-A76 and four Cortex-A55-class cores), a 10 MB L3 cache, the Adreno 680 GPU, and an eight-channel LPDDR4X-4266 memory controller. The SoC is accompanied by 8 GB of RAM as well as 256 GB or 512 GB of NAND flash storage (expandable with a microSD card).
    When it comes to wireless connectivity, the Samsung Galaxy Book S includes Snapdragon X20 LTE modem (Cat 18, 5CA, 4x4 MIMO, depending on the market and operator), 802.11ac Wi-Fi, and Bluetooth 5.0. The PC’s wired connectivity department is limited to USB Type-C that is used for data and charging, a microSD card slot, yet we do not know whether it has a 3.5-mm audio connector.
    As far as imaging and multimedia capabilities are concerned, the Galaxy Book S has a 720p webcam, a built-in microphone as well as Dolby Atmos-badged stereo speakers co-designed with AKG. The laptop also has a Windows Hello-compatible fingerprint reader.
    Apart from performance, one of the key improvements of the Galaxy Book S compared to its predecessor is its longer battery life. The PC comes with a 42 Wh battery that enables it to work for up to 23 hours (based on tests conducted by Samsung), up from 20 hours for last year's device.

    Anandtech: EnGenius Reveals ‘Affordable’ Multi-Gig Switches with PoE: 8 2.5GBASE-T an

    EnGenius has unveiled a new series multi-gigabit PoE++L2+ networking switches with multiple NBASE-T ports. The EnGenius ECS2512FP and ECS2512 switches are designed for small and medium businesses as well as large living environments, and along with their fast switching capabiltiies, one of the models is also capable of Power over Ethernet to deliver power to remote, high-performance devices like Wi-Fi 6 access points. Both models can be managed remotely using EnGenius cloud-based software. The manufacturer is calling its new switches ‘affordable’, though without listing official prices.
    Both new switches from EnGenius — the ECS2512FP and the ECS2512 — support 120 Gbps of switching capacity and are fed via eight 2.5GBASE-T ports along with four 10GbE SFP+ slots for fiber uplinks. Meanwhile, the more advanced ECS2512FP model supports the IEEE 802.3bt Power-over-Ethernet, allowing it to transfer up to 240 W of power to such power-hungry devices as Wi-Fi 6 access points, PTZ cameras, or AV controllers.
    One of the key features of the latest EnGenius switches is their support for the company’s subscription-free EnGenius Cloud that allows to monitor system metrics in real time, display network topology, troubleshoot, problems, and analyze network’s behavior. According to the company, its switches and cloud services provide ‘enterprise-class features’ and essentially simplify monitoring of networks. While such capabilities bring a lot of value for companies, they come at a cost that typically makes these kinds of multi-gig switches prohibitively expensive for consumers.
    EnGenius says that its ECS2512FP and ECS2512 switches will hit the market next month and that they will be ‘affordable’. Unfortunately, without an actual price it is impossible to say whether the switches will be reasonably priced for an average person, or for a business that wants to save on multi-gig network management.
