    Anandtech: Corsair Reveals Vengeance LPX DDR4-4866 Memory Kit

    Corsair on Thursday released its fastest memory kit to date, the Vengeance LPX DDR4-4866, aimed at the most performance-hungry enthusiasts. The modules are specifically tested for compatibility AMD’s Ryzen 3000/X570 platforms, though they can work with Intel-based PCs too.
    Corsair’s Vengeance LPX DDR4-4866 memory kit consists of two 8 GB memory modules (CMK16GX4M2Z4866C18) featuring a CL18 26-26-46 latency and a 1.5V voltage. The unbuffered DIMMs rely on Micron’s cherry-picked DRAM devices as well as Corsair’s custom 10-layer PCB. The modules are traditionally equipped with aluminum heat spreaders, and are compatible Corsair’s Vengeance Airflow fan to improve cooling.
    The manufacturer claims that it has tested its Vengeance LPX DDR4-4866 modules with AMD’s Ryzen 3000-series processors paired with ASUS's ROG Crosshair VIII Formula, the MSI MEG X570 Godlike, and the MSI Prestige X570 Creating motherboards. Meanwhile, since the UDIMMs feature an XMP 2.0 SPD, they will be able to work with Intel Z390-based platforms at DDR4-4800 as well.
    For those who need high-end performance and RGB LEDs as well, Corsair will also offer Vengeance RGB Pro DDR4-4700 16 GB kit. The RGB Pro kit cannot be equipped with a fan, but it will still feature the same DRAM chips, a custom PCB, an XMP 2.0 profile, and aluminum heat spreaders.
    Being a true flagship offering, Corsair’s 16 GB Vengeance LPX DDR4-4866 memory kit is expensive to say the least: in the US the kit costs $984, whereas in Europe it is priced at €1,064,99.
    There is one thing to note about Corsair’s Vengeance LPX DDR4-4866 and Vengeance RGB Pro DDR4-4700 memory kits. AMD as well as third-party observers sayd that the Ryzen 3000 processors show the highest memory subsystem performance when frequencies of Infinity Fabric (fClk), memory controller (uClk), and DRAM (mClk) are equal (i.e., the fClk to mClk ratio is set at 1:1). Which can be an issue, as few Ryzen CPUs can support such high fClk clocks; so using exceptionally fast DDR4 memory modules (e.g., DDR4-4000+) may be unfavorable in many cases. That said, it remains to be seen what kind of advantages will Corsair’s DDR4-4700 and DDR4-4866 kits bring.

    Anandtech: Wi-Fi 6 Is Officially Here: Certification Program Begins

    Wi-Fi Alliance on Monday officially started its Wi-Fi 6 certification program, informally kicking off the widescale adoption of the new Wi-Fi standard. As with the group's previous certification programs, the Wi-Fi 6 certification program is focused on verifying the interoperability and feature sets of IEEE 802.11ax devices, ensuring that they work well with each other and that the devices feature all of the required performance and security capabilities of the new standard.
    Wi-Fi Alliance's certification comes as device manufacturers have already been shipping Wi-Fi 6 products for the last several months – essentially seeding the hardware ecosystem to get to this point. So the first task for the group's members and test labs will be to certify existing Wi-Fi 6 devices. This includes existing access points, routers, and client devices, including Samsung’s Galaxy Note 10, which has become the first smartphone to receive certification.
    Under the hood, the new standard takes a bit of a departure from past Wi-Fi iterations by focusing more on improving performance in shared environments, as opposed to solely boosting peak device transfer rates. To that end, while the maximum throughput supported by Wi-Fi 6 is 2.4 Gbps, the crucial improvement of the Wi-Fi 6/802.11ax technology the standard's enhanced spectral efficiency. Among other things, the technology adds OFDMA (Orthogonal Frequency-Division Multiple Access) to allow different devices to be served by one channel, by dedicating different sub-carriers for individual client devices. Wi-Fi 6 also adds mandatory support for MU-MIMO – a feature first added in 802.11ac Wave 2 – as well as transmit beamforming for better reaching individual clients.
    In fact, even existing Wi-Fi 5 (802.11ac) client devices can benefit from a Wi-Fi 6 (802.11ax) AP, though Wi-Fi 6 Certified devices will deliver the best results.
    Meanwhile, Wi-Fi Alliance mandates that Wi-Fi 6 certified devices support WPA3 security, 1024-QAM, 160 MHz channels, and that devices support target wake time (a battery-saving tech that minimizes device check-ins).
    Finally, along with the launch of the certification program itself, the Wi-Fi Alliance has already certified its first dozen devices. The following network adapters, chipsets, and access points have all been Wi-Fi 6 certified:

    • Broadcom BCM4375
    • Broadcom BCM43698
    • Broadcom BCM43684
    • Cypress CYW 89650 Auto-Grade Wi-Fi 6 Certified
    • Intel Wi-Fi 6 (Gig+) AX200 (for PCs)
    • Intel Home Wi-Fi Chipset WAV600 Series (for routers and gateways)
    • Marvell 88W9064 (4x4) Wi-Fi 6 Dual-Band STA
    • Marvell 88W9064 (4x4) + 88W9068 (8x8) Wi-Fi 6 Concurrent Dual-Band AP
    • Qualcomm Networking Pro 1200 Platform
    • Qualcomm FastConnect 6800 Wi-Fi 6 Mobile Connectivity Subsystem

    Anandtech: CEVA Announces NeuPro-S Second-Generation NN IP

    It’s been a few years since machine learning and neural networks first started to be the hot new news topic. Ever since then, the market has transformed a lot and a lot of companies and the industry as a whole has shifted from a notion of “what can we do with this” to rather a narrative of “this is useful, we should really have it”. Although the market is very much far from being mature, it’s no longer in the early wild-west stages that we saw a few years ago.
    A notable development in the industry is that there’s been a whole lot of silicon vendors who have chosen to develop their own IP instead of licensing things out – in a sense IP vendors were a bit behind the curve in terms of actually offering solutions, forcing in-house developments in order for their product not to fall behind in competitiveness.
    Today, CEVA announces the new second generation of NeuPro neural networks accelerators, the new NeuPro-S. The new offering improves and advances the capabilities seen in the first generation, with CEVA also improving vendor flexibility and a new product offering that embraces the fact that a wide range of vendors now have their own in-house IP.
    The NeuPro-S is a direct successor to last year’s first-generation NeuPro IP, improving on the architecture and microarchitecture. The core improvements of the new generation lie around the way the block now improves and handles memory, including new compression and decompression of data. CEVA quotes figures such as 40% reduces memory footprint and bandwidth savings, all while enabling energy efficiency savings of up to 30. Naturally this also enables for an increase in performance, claiming up to 50% higher peak performance in a similar hardware configuration versus the first generation.
    Diving deeper into the microarchitectural changes, innovations of the new generation includes new weight compression as well as network sparsity optimisations. The weight data is retrained and compressed via CDNN via CEVA’s offline compiler and remains in a compressed form in the machine’s main memory – with the NeuPro-S decompressing in real time via hardware.
    In essence, the new compression and sparsity optimisation sound similar to what Arm is doing in their ML Processor with zero-weight pruning in the models. CEVA further goes on to showcase the compression rate factors that can be achieved – with the factor depending on the % of zero-weights as well as the weight sharing bit-depth. Weight-sharing is a further optimisation of the offline compression of the model which reduces the actual footprint of the weight data by sharing finding commonalities and sharing them across each other. The compression factors here range from 1.3-2.7x in the worst cases with few sparsity improvements to up to 5.3-.7x in models with significant amount of zero weights.
    Further optimisations on the memory subsystem level includes a doubling of the internal interfaces from 128-bit AXI to 256-bit interfaces, enabling for more raw bandwidth between the system, CEVA XM processor and the NeuPro-S processing engine. We’ve also seen an improvement of the internal caches, and CEVA describe the L2 memory utilisation to have been optimised by better software handling.
    In terms of overall scaling of the architecture, the NeuPro-S doesn’t fundamentally change compared to its predecessor. CEVA doesn’t have any fundamental limit here in terms of the implementation of the product and they will build the RTL based on a customer’s needs. What is important here is that there’s a notion of clusters and processing units within the clusters. Clusters are independent of each other and cannot work on the same software task – customers would implement more clusters only if they have a lot of parallel workloads on their target system – for example this would make sense in an automotive implementation with many camera streams, but wouldn’t necessarily see a benefit in a mobile system. The cluster definition is a bit odd and wasn’t quite as clear whether it’s actually any kind of hardware delimitation, or the more likely definition of software operation of different coherent interconnect blocks (As it’s all still connected via AXI).
    Within a cluster, the mandatory block is CEVA’s XM6 vision and general-purpose vector processor. This serves as the control processor of the system and takes care of tasks such as control flow and processing of fully-connected layers. CEVA notes that processing of ML models can be processed fully independently by the NeuPro-S system, whereas maybe other IPs need to still rely on maybe the CPU for some processing of some layers.
    The NeuPro-S engines are naturally the MAC processing engines that add the raw horsepower for wider parallel processing and getting to the high TOPS figures. A vendor needs at minimum a ratio of 1:1 XM to NeuPro engines, however it may chose to employ more XM processors which may be doing separate computer visions tasks.
    CEVA allows allow scaling of the MAC engine size inside a single NeuPro-S block, which ranges from 1024 8x8 MACs to up to 4096 MACs. The company also allows for different processing bit-depths, for example allowing 16x16 as it still sees the need for some use cases that take advantage of the higher precision 16-bit formats. There are also mixed format configurations like 16x8 or 8x16 where the data and weight precision can vary.
    In total, a single NeuPro-S engine in its maximum configuration (NPS4000, 4096 MACs) is quoted as reaching up to 12.5 TOPS on a reference clock of 1.5GHz. Naturally the frequency will vary based on the implementation and process node that the customer will deploy.
    As some will have noted in the block diagram earlier, CEVA also now allows the integration of third-party AI engines into their CDNN software stack and to interoperate with them. CEVA calls this “CDNN-Invite”, and essentially the company here is acknowledging the existence of a wide-range of custom AI accelerators that have been developed by various silicon vendors.
    CEVA wants to make available their existing and comprehensive compiler and software to vendors and enable them to plug-in their own NN accelerators. Many vendors who chose to go their own route likely don’t have quite as extensive software experience or don’t have quite as much resources developing software, and CEVA wants to enable such clients with the new offering.
    While the NeuPro-S would remain a fantastic choice for generic NN capabilitites, CEVA admits that there might be custom accelerators out there which are hyper-optimised for certain specific tasks, reaching either higher performance or efficiency. Vendor could thus have the best of both worlds by having a high degree of flexibility, both in software and hardware. One could choose to use the NeuPro-S as the accelerator engine, use just their own IP, or create a system with both units. The only requirement here is that a XM processor be implemented as a minimum.
    CEVA claims the NeuPro-S is available today and has been licensed to lead customers in automotive camera applications. As always, silicon products are likely 2 years away.

    Anandtech: NVIDIA Announces Call of Duty: Modern Warfare Game Bundle for GeForce RTX

    With the arrival of Fall also comes the biggest quarter of the year for new game releases, and to that end NVIDIA is updating their hardware game bundles. This morning the company is announcing a new bundle for their GeForce RTX cards, which will see the latest Call of Duty game, Modern Warfare, included with the cards as well as systems containing them. This latest bundle is currently scheduled to run through mid-November, or until NVIDIA updates it once more.
    Like previous NVIDIA GeForce RTX game bundles, the Call of Duty: Modern Warfare bundle is focused on including a flagship game that showcases the features of NVIDIA’s newest cards. In this case, Modern Warfare checks all of the boxes; along with being a high-profile game in and of itself, the game is receiving (practically obligatory) support for ray tracing via DXR, as well as adaptive shading support.
    Digging into the bundle itself, as this is a single game bundle, NVIDIA’s deal is pretty straightforward. The company will be including the game with all of their GeForce RTX cards, from the RTX 2060 up to the RTX 2080 Ti. This offer also applies to many desktop and laptop systems including these cards as well, so long as the vendor is a participating NVIDIA partner.
    NVIDIA Current Game Bundles
    (September 2019)
    Video Card Bundle
    GeForce RTX 20 Series (All) Call of Duty: Modern Warfare (2019)
    GeForce GTX 16 Series (All) None
    Meanwhile, the fact that this is an RTX-only bundle means that NVIDIA’s GTX 16 series cards are being left out. The company has not launched a bundle for those cards, so at least for the time being, only the RTX 20 cards are getting a game bundle.
    Finally, as always, codes must be redeemed via NVIDIA Redemption portal on a system with a qualifying graphics card installed. More information and details can be found in the terms and conditions. Be sure to verify the participation of any vendors purchased from, as NVIDIA will not give codes for purchases made from non-participating sellers.

    Anandtech: Reaching for Turbo: Aligning Perception with AMD’s Frequency Metrics

    For those that keep a close eye on consumer hardware, AMD recently has been involved in a minor uproar with some of its most vocal advocates about the newest Ryzen 3000 processors. Some users are reporting turbo frequencies much lower than advertised, and a number of conflicting AMD partner posts have generated a good deal of confusion. AMD has since posted an update identifying an issue and offering a fix, but part of all of this comes down to what turbo means and how AMD processors differ from Intel. We’ve been living on Intel’s definitions of perceived standards for over a decade, so it’s a hard nut to crack if everyone assumes there can be no deviation from what we’re used to. In this article, we’re diving at those perceived norms, to shed some light on how these processors work.

    Anandtech: GIGABYTE’s Aorus CV27Q Curved ‘Tactical’ Monitor: 165 Hz QHD With FreeSync

    GIGABYTE has introduced a new display aimed at hardcore gamers, incorporating a multitude of capabilities aimed at the target audience. Dubbed the ‘Tactical Monitor’, the Aorus CV27Q is a QHD curved LCD that's able to run at up to 165Hz, and includes support for AMD’s FreeSync 2 refresh rate technology. The gaming-focused monitor also includes active noise canceling, GameAssist OSD functions, and RGB stripes that can be controlled using the company’s software.
    The GIGABYTE Aorus CV27Q is based on an 8-bit 27-inch curved VA panel featuring a 2560×1440 resolution, 400 nits peak brightness, a 3000:1 static contrast ratio, a maximum refresh rate of 165Hz, a 1 ms MPRT response time, and 178°/178° viewing angles. The panel also sports a 1500R curvature, which means that it provides a wider field of view than most 27-inch LCDs available today.
    As mentioned previously, the Aorus CV27Q is an AMD FreeSync 2-certified monitor, meaning that the display meets AMD's minimum requirements for HDR contrast ratios and color gamuts, as well as supporting direct-to-display tonemapping, and low framerate compensation (LFC) mode. Officially, the monitor is able to hit 90% of the DCI-P3 color gamut, and while it meets the requirements for HDR it only hits the minimum, with an HDR brightness of 400 nits (and matching DisplayHDR 400 certification). Judging from Gigabyte's specifications, it looks like this is an edge-lit monitor – Gigabyte doesn't list how many zones it has – which would be consistent with that performance level. As for FreeSync 2 range, the manufacturer says it is between 48 Hz and 165 Hz.
    Meanwhile, GIGABYTE has informed us that they have also submitted the device to NVIDIA for G-Sync Compatible certification, so that the monitor's variable refresh modes can be used with GeForce cards. Whether this happens is ultimately up to NVIDIA – which is why GIGABYTE isn't advertising it as a feature quite yet – but as the company already has other monitors that have been certified by NVIDIA, GIGABYTE should have the expertice to pass certification here as well.

    Moving on to gaming-specific features of the Aorus CV27Q, one of the capabilities that GIGABYTE is especially proud of is its 2nd Generation active noise canceling (ANC) technology. Here, ANC uses a special chip along with a dual mic setup to remove ambient noises from the background of the microphone feed. Meanwhile on the output side of matters, GIGABYTE claims that the monitor offers a 120 dB signal-to-noise-ratio (SNR), with the monitor able to support high impedance headphones up to 600 Ohm.
    Another interesting capability is Black Stabilizer 2.0 that promises to improve details of dark parts of a scene without affecting other areas. This sounds vaguely like local dimming, however with an edge-lit monitor it's not clear that this monitor will have enough zones to use it effectively. Other features driven by the firmware include crosshair, aim stabilizer (which reduces motion blur in fast-paced scenes, though GIGABYTE does not disclose how it does it), timer & counter, as well as OSD Sidekick that allows to tune the monitor to a particular game or situation.
    To connect the GIGABYTE Aorus CV27Q to PCs and consoles, the monitor has one DisplayPort 1.4 and two HDMI 2.0 connectors. Furthermore, the LCD has a dual-port USB 3.0 hub as well as as 3.5-mm audio jacks for headphones and a mic. As far as ergonomics is concerned, the display comes with a stand that can adjust height, tilt, and swivel.
    The GIGABYTE Aorus CV27Q
    General Specifications

    Anandtech: HP’s Unveils Elite Dragonfly Laptop: 13.3-Inch Convertible With a 24.5 Hou

    HP this morning is introducing its new flagship 13.3-inch convertible laptop, which the company is calling the Elite Dragonfly. The Project Athena-class laptop is designed to check all of the boxes for a high-end, compact laptop, offering premium features, a very low weight, and most interesting of all, an optional high-capacity battery that HP claims will run the laptop for over 24 hours.
    The HP Elite Dragonfly notebook comes in a CNC-machined magnesium alloy chassis, which has allowed HP to reduce its weight to around 990 grams (in case of the low-weight SKU with a 38 Wh battery) and maintain a 1.61 cm z-height. According to HP, the chassis also meets the durability requirements for the MIL-STD 810G standard (including spill resistance), so it looks like HP has been able to cut down on weight without compromising the durability of the laptop. Meanwhile, the entire chassis is covered with an oleophobic coating, to make the entire laptop resistant to fingerprints and smudges.
    Front and center of the convertible notebook is the 13.3-inch touch-enabled display, which is available in Full HD (1080p) or Ultra HD (4K) resolutions, and options include a version of the FHD panel that incorporates Intel's 1 Watt panel tech. The display panel itself is protected by Corning’s Gorilla Glass 5, and for the privacy-minded, HP is also offering their SureView privacy screen as an option.
    HP says that it has taken it a long time to engineer a laptop that could include all of the Elite Dragonfly's features, and to that end it has to stick to Intel’s proven low-power 8th Gen Core i3/i5/i7 processors (Whiskey Lake). Despite usage of a previous-generation CPU, the Elite Dragonfly is compliant with Intel's Project Athena requirements, so overall experience should be in line with other laptops designed for that program. The CPU is accompanied by up to 16 GB of soldered-down dual-channel LPDDR3-2133 memory as well as an SSD with capacities going up to 2 TB. Higher-end SKUs will use a PCIe 3.0 x4 drive, whereas cheaper or specialized models will come with a SATA drive, allowing HP to offer a FIPS 140-2-certified drive to customers who need it.
    Communications are critical for business these days, so this is where the Elite Dragonfly excels. The convertible laptop comes with Intel’s Wi-Fi 6 + Bluetooth 5 adapter, an optional Intel XMM 7360/7560 4G/LTE modem with 4x4 antennas, and an optional GbE adapter. Meanwhile, when it comes to wired connectivity the laptop includes a Thunderbolt 3-enabled USB-C port, a stand-alone USB-C port, a USB Type-A port, a full-size HDMI port, and a 3.5-mm audio connector. Speaking of audio, when not using headphones the PC has four Band & Olufsen-badged speakers as well as a microphone array as its disposal.
    Being an Elite-branded laptop, the HP Dragonfly supports all the key security features that the manufacturer has to offer. In addition to HP SureView privacy screen as well as a 720p Privacy Camera (with or without IR sensor), the convertible supports HP’s Sure Sense, Sure Recover, and Embedded Reimaging technologies, a TPM 2.0 module, and an Absolute persistence module.
    Meanwhile, when it comes to battery life, HP is making some bold claims, stating that that an Elite Dragonfly equipped with a Core i5 processor, 8 GB of RAM, a 128 GB SSD, and a 1-Watt Full-HD display, and a 56.2 Wh battery can last for up to 24 hours and 30 minutes on a single charge. These results are based on MobileMark 2014, a relatively light workload, so results will vary with the workload used. Meanwhile, machines with other configurations (e.g. a smaller battery) will last for a shorter amount of time.
    HP intends to start sales of its Dragonfly laptops on October 25. Prices for the entry-level Dragonfly convertibles will start at $1,549, but higher-performance SKUs will cost significantly more. In addition the the PC itself, the company will offer a travel mouse as well as a leather sleeve.

    Anandtech: The OPPO Reno 10x Zoom Review: Bezeless Zoom

    The Oppo Reno 10x Zoom is another Snapdragon 855-based phone that was released earlier in the year, and while we did a quick hands-on test of the device back in May, we never really got to fully reviewing the unit until now. Beyond putting the Reno 10x through our usual testing suite, what’s interesting is that in this time Oppo has had the opportunity to refine the software, and we’ve seen particular improvements on the side of the camera with the introduction of a new low-light photography mode.
    The device has two key characteristics: A full-screen minimal bezel display which is enabled by housing the front-camera in a mechanical motorised slide-out mechanism, and a triple-camera setup amongst which we find a “periscope” zoom camera module. Both of these features separately aren’t unique to the Reno 10x, however their combination is unique to Oppo.

    Anandtech: Intel Core i9-9900KS TDP Details: ASUS Maximus XI Apex Support

    Intel announced plans to launch its eight-core Core i9-9900KS processor along with its performance specifications quite a while ago, but the company did not disclose the TDP. As the processor will have an all-core base frequency of 4.0 GHz and an all-core turbo of 5.0 GHz, this number is vitally important for motherboard support. This week ASUS released a new BIOS version for some of its motherboards that adds support for the Core i9-9900KS and revealed the number.
    The Intel Core i9-9900 processor has a base frequency of 4.0 GHz as well as an all-core turbo frequency of 5.0 GHz, which essentially makes it an eight-core Coffee Lake Refresh silicon binned to hit higher clocks when cooling is good enough. As it turns out, in a bid to enable higher frequencies, Intel has increased the TDP all the way to 127 W (according to a listing at ASUS.com), which is considerably higher when compared to any existing (or historical) Intel’s CPU for mainstream platforms.
    One thing that should be noted is that Intel only guarantees base frequency at a rated TDP (e.g., 4.0 GHz at 127 W), so everything above base (i.e., turbo clocks) means a higher power consumption. As a result, not only will the Core i9-9900KS require a motherboard that can supply 127 W of power and a cooling system that will dissipate 127 W of power, but it will need an advanced platform to hit the turbo clocks. Fortunately, there are plenty of high-end motherboards and coolers around to support the Core i9-9900KS.

    One thing to keep in mind is that the information about the TDP of the Core i9-9900KS comes from a third party (albeit a very reliable one), not from Intel. Intel has confirmed that the new Core i9-9900KS will be released in October.
