TechPowerUp today released the latest version of the popular GPU-Z graphics sub-system information, monitoring, and diagnostic utility. Version 2.59.0 adds support for new GPUs, but also fixes a few important issues with the application. To begin with, support is added for the NVIDIA RTX 2000 Ada and RTX 1000 Ada Laptop GPUs. An application launch error on Windows 7 and Windows 8 systems reading "unsigned driver cannot load" has been fixed.

The other issues resolved mainly concern the way PCI resizable BAR status is detected. On external GPUs, resizable BAR status was appearing as "enabled." This has been fixed. eGPUs lack resizable BAR support due to the limitations of USB interconnect. On notebooks with NVIDIA Optimus GPUs that support resizable BAR, the status was being reported as "disabled" when the discrete GPU is sleeping, which has been fixed. Lastly, instances where resizable BAR support is reporting as "Yes" instead of "enabled" or "disabled" has been fixed. Grab TechPowerUp GPU-Z from the link below.

February saw community mods bring resizable BAR support to several older platforms; and now we come across a mod that brings it to some older GPUs. The NVStrapsReBAR mod by terminatorul, which is forked out of the ReBarUEFI mod by xCurio, brings resizable BAR support to NVIDIA GeForce RTX 20-series and GTX 16-series GPUs based on the "Turing" graphics architecture. This mod is intended for power users, and can potentially brick your motherboard. NVIDIA officially implemented resizable BAR support since its RTX 30-series "Ampere" GPUs in response to AMD's Radeon RX 6000 RDNA 2 GPUs implementing the tech under the marketing name Smart Access Memory. While AMD would go on to retroactively enable the tech for even the older RX 5000 series RDNA GPUs, NVIDIA didn't do so for "Turing."

NVStrapsReBAR is a motherboard UEFI firmware mod. It modifies the way your system firmware negotiates BAR size with the GPU on boot. There are only two ways to go about modding a platform to enable resizable BAR on an unsupported platform—by modding the motherboard firmware, or the video BIOS. Signature checks by security processors in NVIDIA GPUs make the video BIOS modding route impossible for most users; thankfully motherboard firmware modding isn't as difficult. There is an extensive documentation by the author to go about using this mod. The author has tested the mod to work with "Turing" GPUs, however, it doesn't work with older NVIDIA GPUs, including "Pascal." Resizable BAR enables the CPU (software) to see video memory as a single contiguously addressable block, rather than through 256 MB apertures.

MSI released an intriguing AMI BIOS update on January 31 for their Intel 700 and 600 chipset mainboards—hardware tipster chi11eddog noticed this quiet announcement and proceeded to get his Z790 Carbon MAX WIFI motherboard running on beta version 7D89v1B1. This preliminary release enables "capacity support up to 256 GB" for DDR5 Memory—chi11eddog noted that you previously had to jump through several hoops to get this configuration in working order: "As per a friend in the industry, before this, it needs to disable Above 4G/Resizable BAR/remapping to support 256 GB on Intel systems. MSI has fixed this. No need to disable Above 4G/Resizable Bar."

His MSI Z790 test platform featured an Intel Core i9-14900K CPU and 256 GB (4 x 64 GB) DDR5-4800 of memory—Wccftech's reportage proposes some extra tests: "it would be interesting to see what the maximum speeds are supported when using high-capacity memory kits but for those who prefer capacity over speed, well the solutions are now out there." The Compression Attached Memory Module (CAMM) standard has been adopted by the laptop memory segment, and manufacturers are believed to be transferring technological innovations to desktop form factors. Upcoming 64 GB DDR5 modules offer twice the capacity over the best previous-gen solutions. The proliferation of non-binary DIMM kits—from 24 to 48 GB—in 2023 brought (total) desktop memory capacities to a maximum of 192 GB.

Intel Graphics releases Arc GPU Graphics Drivers version 101.4369 WHQL. These drivers significantly improve performance for "The Outlast Trials," with gains of up to 65% and 52% to be had at 1080p and 1440p, respectively, compared to the previous 101.4355 drivers. The drivers also offer 4% to 11% uplifts for "Starship Troopers: Extermination" Early Access. The drivers introduce an all new version of Arc Control, which adds fan speed settings, VRR control, a new Search bar that finds features and settings; improved background replacement for virtual camera, and the ability to select more than one device for telemetry. It also fixes UAC requirements to launch Arc Control, improved Resizable BAR status reporting, and live performance monitoring.

Microsoft has implemented two new features into its DirectX 12 API - GPU Upload Heaps and Non-Normalized sampling have been added via the latest Agility SDK 1.710.0 preview, and the former looks to be the more intriguing of the pair. The SDK preview is only accessible to developers at the present time, since its official introduction on Friday 31 March. Support has also been initiated via the latest graphics drivers issued by NVIDIA, Intel, and AMD. The Microsoft team has this to say about the preview version of GPU upload heaps feature in DirectX 12: "Historically a GPU's VRAM was inaccessible to the CPU, forcing programs to have to copy large amounts of data to the GPU via the PCI bus. Most modern GPUs have introduced VRAM resizable base address register (BAR) enabling Windows to manage the GPU VRAM in WDDM 2.0 or later."

They continue to describe how the update allows the CPU to gain access to the pool of VRAM on the connected graphics card: "With the VRAM being managed by Windows, D3D now exposes the heap memory access directly to the CPU! This allows both the CPU and GPU to directly access the memory simultaneously, removing the need to copy data from the CPU to the GPU increasing performance in certain scenarios." This GPU optimization could offer many benefits in the context of computer games, since memory requirements continue to grow in line with an increase in visual sophistication and complexity.

Support for AMD's Smart Access Memory and the overarching Resizable BAR technologies has been removed from the RadeonSI Gallium3D OpenGL driver as of today's Mesa 22.3.7 release. The comment in the announcement simply reads, "Disable Smart Access Memory because CPU access has large overhead." The nail in the coffin seems to have been this bug ticket submitted last month for the game Hyperdimension Neptunia Re;Birth1, in which the user reported the game running oddly slow on their RX 6600 while previously they had no issues on the much older R9 380. The solution provided was to simply disable ReBAR/SAM either with radeonsi_disable_sam=true or via UEFI. In the comments of the ticket lead RadeonSI developer Marek Olšák states, "We've never tested SAM with radeonsi, and it's not necessary there."

Apparently the performance advantages weren't panning out for RadeonSI, and since direct optimizations of these features was not a primary goal the decision was made to cut them out. Attempts to optimize SAM with RadeonSI date as far back as December 2020 and Mesa 21.0, but support for SAM under Linux goes further back. None of the changes to RadeonSI will affect other drivers such as RADV, the open-source Radeon Vulkan driver, and this code change is limited to only the RadeonSI OpenGL driver.

The PCI Resizable BAR feature can have a major impact on the performance of "Dead Space" (the 2023 reboot). sxKYLE on Reddit discovered that his GeForce RTX 4080 "Ada" experienced a major performance jump from 76 FPS up to 111 FPS (+46%) with resizable BAR enabled. NVIDIA Profile Inspector was used to enable resizable BAR for the game. The feature allows the CPU to see the graphics card's video memory as a single, continuously-addressable block, rather than through 256 MB apertures. We can imagine how "Dead Space" in particular could benefit from the feature, as the game's campaign is a single continuous action sequence with assets being constantly streamed to the GPU (and no level load screens).

Intel has recently published a document outlining the requirements for Arc GPU support on desktop including the supported platforms. The guide states that supported processors are limited to 12th Gen Core "Alder Lake", 11th Gen Core "Rocket Lake", and 10th Gen Core "Comet Lake" with Resizable BAR support enabled on the motherboard. The document also notes that other platforms supporting Resizable BAR / Smart Access Memory may work with Intel Arc graphics cards indicating potential unofficial support for AMD platforms also. Intel has also specified that only Windows 10/11 is supported and installations must be using the GPT partition type. The page contains instructions to enable Resizable BAR support and switch to a GPT partition but no information is provided as to whether the cards will work without this functionality.

AMD today unveiled its next-generation Ryzen 7000 desktop processors, based on the Socket AM5 desktop platform. The new Ryzen 7000 series processors introduce the new "Zen 4" microarchitecture, with the company claiming a 15% single-threaded uplift over "Zen 3" (16-core/32-thread Zen 4 processor prototype compared to a Ryzen 9 5950X). Other key specs about the architecture put out by AMD include a doubling in per-core L2 cache to 1 MB, up from 512 KB on all older versions of "Zen." The Ryzen 7000 desktop CPUs will boost to frequencies above 5.5 GHz. Based on the way AMD has worded their claims, it seems that the "+15%" number includes IPC gains, plus gains from higher clocks, plus what the DDR4 to DDR5 transition achieves. With Zen 4, AMD is introducing a new instruction set for AI compute acceleration. The transition to the LGA1718 Socket AM5 allows AMD to use next-generation I/O, including DDR5 memory, and PCI-Express Gen 5, both for the graphics card, and the M.2 NVMe slot attached to the CPU socket.

Much like Ryzen 3000 "Matisse," and Ryzen 5000 "Vermeer," the Ryzen 7000 "Raphael" desktop processor is a multi-chip module with up to two "Zen 4" CCDs (CPU core dies), and one I/O controller die. The CCDs are built on the 5 nm silicon fabrication process, while the I/O die is built on the 6 nm process, a significant upgrade from previous-generation I/O dies that were built on 12 nm. The leap to 5 nm for the CCD enables AMD to cram up to 16 "Zen 4" cores per socket, all of which are "performance" cores. The "Zen 4" CPU core is larger, on account of more number-crunching machinery to achieve the IPC increase and new instruction-sets, as well as the larger per-core L2 cache. The cIOD packs a pleasant surprise—an iGPU based on the RDNA2 graphics architecture! Now most Ryzen 7000 processors will pack integrated graphics, just like Intel Core desktop processors.

TechPowerUp today released the latest version of TechPowerUp GPU-Z, the popular graphics sub-system information, diagnostic, and monitoring utility. Version 2.46.0 introduces support for the AMD Radeon RX 6950 XT, RX 6750 XT, and RX 6650 XT. It also improves support for Intel Arc "Alchemist" GPUs. Support is added for rare graphics cards, such as the GA107-based GeForce RTX 2050, and NVIDIA A30. Support is also improved for Xe LP-based iGPUs in "Alder Lake" mobile processors, and the Glenfly GPU. The core driver of GPU-Z has been updated to no longer require an SSE2-capable CPU. AMD's 2022-series drivers are correctly labeled as "AMD Software." Resizable BAR misreading on AGP graphics cards has been fixed.

TechPowerUp today released the latest version of TechPowerUp GPU-Z, the handy graphics sub-system information and diagnostic utility for gamers and PC enthusiasts. Version 2.44.0 adds support for several new GPUs, feature updates to the Resizable BAR detection, and a handful other fixes. To begin with, GPU-Z adds support for NVIDIA GeForce RTX 3050, RTX 3080 12 GB, RTX 3070 Ti Mobile, RTX 3050 Ti Mobile, RTX 2060 12 GB, MX550, and a number of other mobile GPUs from NVIDIA. On the AMD front, you get support for Navi 24: Radeon RX 6500 XT, RX 6400, RX 6300M, RX 6500M, PRO W6300M, PRO W6500M, and PRO W660M. Support is also added for Intel "Alder Lake" non-K processors, "Alder Lake" mobile processors, and Xeon processors based on "Rocket Lake."

TechPowerUp GPU-Z can now report the exact base-address register (BAR) size when Resizable BAR is enabled. Find it in the Advanced Panel, under Resizable BAR. Detection of Resizable BAR has been improved. Detection of LHR in certain RTX 3060 cards has been improved to weed out misreporting of LHR. Vendor detection was added for Vastarmor. The internal Screenshot hosting utility now uploads screenshots over HTTPS. The 64-bit Windows Vista name will now include a space character, so "Vista 64" instead of just "Vista64."

AMD today released the latest version of Radeon Software Adrenalin. Version 21.9.1 is feature-packed with stuff enthusiasts are bound to love. To begin with, it introduces Smart Access Memory (PCI Resizable BAR) support for AMD Radeon RX 5000 series (RDNA) graphics processors, when used with a compatible platform. Next up, it adds optimization for "Call of Duty Vanguard Open Beta," and "Deathloop." The drivers also add a handful Vulkan API extensions, including VK_KHR_zero_initialize_workgroup_memory, VK_KHR_shader_integer_dot_product, VK_EXT_shader_atomic_float2, and VK_EXT_load_store_op_none. Perhaps the biggest new feature addition is AMD Auto Overclock.

On machines with AMD Ryzen 5000 series processors and Radeon RX 6000 series graphics, the Auto-Overclock feature detects CPU load, and automatically overclocks it in increments of 50 MHz, beyond the processor's rated maximum boost frequency. Just like manual overclocking, this comes with sizable costs to power consumption and cooling. The feature also automatically overclocks your RX 6000 series GPU. Using the feature is as easy as pulling up the Tuning tab in Radeon Software, and clicking on "Auto Overclock" in the Tuning Control tab. Lastly, Adrenalin 21.9.1 adds support for the upcoming Windows 11 operating system. The software is released alongside AMD's latest 3.09.01.140 Chipset Software, which also add Windows 11 support. A handful bugs have also been fixed, as described below.

AMD today announced the new Radeon RX 6600 XT graphics card, its latest entrant to the RX 6000 series, based on the RDNA2 graphics architecture, with full DirectX 12 Ultimate support, including raytracing. The RX 6600 XT is suitable for AAA gaming at 1080p, or e-sports gaming at 1440p. The card debuts the new 7 nm Navi 23 silicon to the desktop, and maxes it out. It is endowed with 2,048 stream processors across 32 RDNA2 compute units, 128 TMUs, 32 ROPs, and a 128-bit wide memory interface, holding 8 GB of GDDR6 memory running at 16 Gbps (256 GB/s bandwidth). The chip also has 32 MB of Infinity Cache memory. With a board power of 160 W, the card can make do with a single 8-pin PCIe power connector. The game clocks are up to 2359 MHz.

As for performance, AMD claims that the RX 6600 XT offers a 2.2-2.5 times performance gain over the GeForce GTX 1060, providing a viable upgrade. It also offers a 40% performance uplift over the previous-generation RX 5600 XT, and runs consistently faster than the RX 5700, perhaps even trading blows with the RX 5700 XT. In the current generation, AMD claims a 15% performance lead over the GeForce RTX 3060 on average, with both cards having Resizable BAR / Smart Access Memory enabled, at 1080p. Available from August 10, the card starts at USD $379, and is a partner-exclusive, meaning that only custom-design cards will be available, the company will not sell reference design ones.

Alongside Intel's launch of the 11th Gen Core "Tiger Lake-H" desktop processor series, NVIDIA debuted its mid-range GeForce RTX 3050 Ti (mobile) and RTX 3050 (mobile) graphics processors. Both chips are designed with typical 3D power ranging between 35 W and 80 W. Both chips are based on the new 8 nm "GA107" silicon. This "Ampere" chip physically packs 2,560 CUDA cores across 20 streaming multiprocessors, with 80 tensor cores, 20 RT cores, and a 128-bit wide GDDR6 memory interface.

The GeForce RTX 3050 Ti (mobile) appears to be maxing out the GA107 silicon, featuring all 2,560 CUDA cores, 80 tensor cores, 20 RT cores, and 4 GB of GDDR6 memory across the chip's 128-bit wide memory bus. The RTX 3050 is slightly cut down, with 16 out of 20 SM enabled. This works out to 2,048 CUDA cores, 64 tensor cores, and 16 RT cores. The memory remains the same—4 GB GDDR6. Clock speeds will vary wildly depending on the notebook model, but typically, the RTX 3050 Ti can boost up to 1695 MHz, while the RTX 3050 can boost up to 1740 MHz. Both chips take advantage of PCI-Express 4.0 and Resizable BAR. The company didn't reveal memory clocks.

EVGA GeForce RTX 30 Series utilizing NVIDIA Resizable BAR gives gamers an extra boost in gameplay framerate on select titles by letting the CPU directly access the GPU's entire frame buffer memory. EVGA Precision X1 simplifies the upgrade process and makes it more intuitive, so you can spend less time updating software and firmware and get back to your gaming! All EVGA GeForce RTX 30 Series now feature support for NVIDIA Resizable BAR after updating a brand new EVGA VBIOS.

TechPowerUp today released the latest version of TechPowerUp GPU-Z, the popular graphics subsystem information and monitoring utility. With the latest version 2.38.0, we are introducing the ability to detect Resizable BAR support. GPU-Z can now tell whether Resizable BAR is supported, and if so, whether it is enabled. AMD refers to Resizable BAR as AMD Smart Access Memory, but it is a feature developed by the PCI-SIG, which lets your CPU see the entire video memory of your discrete graphics card as a single addressable block, rather than through 256 MB apertures. This feature has been found to improve performance in games that can take advantage of it. Resizable BAR status can now be viewed from the main tab, right next to the multi-GPU status.

The latest TechPowerUp GPU-Z also adds support for new and upcoming GPUs, including AMD Radeon RX 6700 XT, RX 6700, RX 6600 XT, RX 6600, and Ryzen "Lucienne" mobile processor iGPUs. Support is also added for NVIDIA GeForce RTX 3070 Mobile. Other new features include the ability to monitor negative temperatures on NVIDIA GPUs. We fixed video BIOS extraction on AMD RDNA2 GPUs (Radeon RX 6000 series). Grab GPU-Z from the link below.

AMD in its "Where Gaming Begins Episode 3" online event, announced that it is introducing Smart Access Memory (resizable base address register) support to Ryzen 3000 series "Matisse" processors, based on the "Zen 2" microarchitecture. These exclude the Ryzen 3 3200G and Ryzen 5 3400G. The PCI-SIG innovated feature was, until now, restricted to the Ryzen 5000 series on the AMD platform, although is heavily proliferated across the Intel platform. Resizable BAR enables the CPU to see the graphics card's entire dedicated memory as one addressable block, rather than through 256-megabyte apertures. For game engines that are able to take advantage of the feature, this could translate to a performance boost of up to 16 percent. Be on the lookout for BIOS updates from your motherboard manufacturer.

Our initial support for "Resizable BAR" is available now for GeForce RTX 3060 desktop graphics cards and GeForce RTX 30 Series laptops. Utilizing an advanced feature of PCI Express, Resizable BAR can increase performance in certain games. Support for other desktop GPUs will follow in late March. Resizable BAR is an optional PCI Express interface technology. As you move through a world in a game, GPU memory (VRAM) constantly transfers textures, shaders and geometry via many small CPU to GPU transfers. With the ever-growing size of modern game assets, this results in a lot of transfers. Using Resizable BAR, assets can instead be requested as-needed and sent in full, so the CPU can efficiently access the entire frame buffer. And if multiple requests are made, transfers can occur concurrently, rather than queuing.

GeForce RTX 30 Series laptops with Resizable BAR-capable Intel and AMD CPUs are available now. Check with each laptop manufacturer to discover if Resizable BAR is supported on a particular model. For desktops, you will need a compatible CPU, compatible motherboard, motherboard SBIOS update, GPU VBIOS update (the GeForce RTX 3060 already ships with the necessary BIOS) and new GeForce Game Ready driver to enable Resizable BAR.

EVGA has recently released new BIOS updates for their X299, Z590, and Z490 motherboards enabling support for the PCIe Resizable BAR feature. Resizable BAR is an optional feature of the PCIe specifications which allows the CPU to access more GPU memory theoretically offering greater performance. AMD released their implementation of Resizable BAR with Smart Access Memory on Radeon RX 6000 Series graphics cards. NVIDIA responded by announcing plans to add Resizable BAR support to their RTX 30 series graphics cards starting with the RTX 3060. This new BIOS update for recent EVGA Intel motherboards will ensure that you can take full advantage of the latest graphics cards. When we tested AMD's Smart Access Memory with the Radeon RX 6800 XT we saw an average performance improvement of 2%.

EVGAThere is a new BIOS update for the EVGA X299 lineup, adding Resizable BAR support! The EVGA Z590, Z490, and X299 motherboards support this feature.

MSI announced that it will begin rolling out UEFI firmware updates for its Socket AM4 motherboards based on the AMD 400-series and 500-series chipsets, which incorporate AMD's latest AGESA Combo PI V2 1.2.0.0 microcode. These firmware updates will enable resizable BAR support for NVIDIA GeForce RTX 30-series "Ampere" graphics cards, improvements for Ryzen 5000 series "Vermeer" desktop processors, and an assortment of board model-specific improvements or fixes.

The company will begin releasing these firmware updates for its AMD 500-series chipset motherboards, and its AMD 400-series "MAX" models in January 2021. In February, it will follow up with updates for AMD 400-series non-"MAX" models. The "MAX" model name suffix for an MSI AMD 400-series motherboard denotes a board with a 32-megabyte SPI flash ROM chip that allows MSI to cram in its feature-rich ClickBIOS setup program. Keep checking the "support" section of your motherboard's product page on the MSI website for these firmware updates.

NVIDIA today announced that it is bringing the NVIDIA Ampere architecture to millions more PC gamers with the new GeForce RTX 3060 GPU. With its efficient, high-performance architecture and the second generation of NVIDIA RTX, the RTX 3060 brings amazing hardware raytracing capabilities and support for NVIDIA DLSS and other technologies, and is priced at $329.

NVIDIA's 60-class GPUs have traditionally been the single most popular cards for gamers on Steam, with the GTX 1060 long at the top of the GPU gaming charts since its introduction in 2016. An estimated 90 percent of GeForce gamers currently play with a GTX-class GPU. "There's unstoppable momentum behind raytracing, which has quickly redefined the new standard of gaming," said Matt Wuebbling, vice president of global GeForce marketing at NVIDIA. "The NVIDIA Ampere architecture has been our fastest-selling ever, and the RTX 3060 brings the strengths of the RTX 30 Series to millions more gamers everywhere."

Intel has apparently taken the CES opportunity to showcase its upcoming Rocket Lake-S CPU in gaming against one of AMD's best mainstream CPUs, packing 12 cores - although the specific model remains undisclosed. Geeknetics shared screen-grabs from the demo, done inside Metro Exodus, where the undisclosed Intel 8-core Rocket Lake-S is shown achieving higher average frame-rates compared to the AMD solution (an average of 156.54 FPS for Intel, against 147.43 FPS for AMD). The CPUs were paired with an NVIDIA RTX 3080 graphics card - and in case you're wondering whether NVIDIA's Resizable BAR capabilities have been activated for this Rocket Lake-S system, no information on that was available at time of writing (the question is raised since Intel has already announced support for the feature with NVIDIA GPUs on Tiger Lake-H).

GIGABYTE TECHNOLOGY Co. Ltd, a leading manufacturer of motherboards, graphics cards, and hardware solutions, today announced that all Z490 motherboards featuring PCIe 4.0 hardware design can support the 11th Gen. Intel Core processors perfectly by update to the latest F20 BIOS, and provide the extreme bandwidth and performance for PCIe 4.0 graphics cards and SSDs. With a snap update of the latest BIOS from GIGBAYTE's official site, users can enjoy the full pack of advantages and unlock the Resizable BAR function on GIGABYTE Z490 and H470 motherboards.

The latest 11th Gen. Intel Core processors will be launched on March 2021. The new processors keep the same architecture as the previous generation but they enable the PCIe 4.0 support, which meet a range of needs for users who expect broad bandwidth and super high transfer speed of PCIe 4.0 on the Intel platform. For those who own one of the current generation motherboards, it would be a great deal to enjoy the performance uplift on Z490 motherboards with PCIe 4.0 function and 11th Gen. Intel Core processors support.
