TechPowerUp GPU-Z v2.38.0 Released

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 Brings Smart Access Memory (Resizable BAR) Support to Ryzen 3000 Series

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.

NVIDIA Details its Resizable-BAR Feature Rollout, Eligible Products

NVIDIA on Tuesday announced a roll-out of its implementation of the PCI-SIG resizable base-address register (BAR) feature to select GeForce products. The feature enables your CPU to see the entire video memory of your graphics card as one addressable block, rather than through 256 MB apertures. This should improve certain kinds of 3D rendering workloads, and game engines that are optimized to use it should see a tangible performance boost. AMD earlier introduced the exact same feature under its marketing name "Smart Access Memory," with its Radeon RX 6000 series.

NVIDIA announced that resizable-BAR support will be made available to GeForce RTX 30-series "Ampere" desktop graphics cards, notebooks that have RTX 30-series "Ampere" mobile GPUs, and future products. The support requires not just a compatible graphics card, but also a motherboard that supports the feature. Most leading motherboard- and OEM desktop manufacturers began rolling out resizable-BAR support through UEFI firmware updates. Using the feature requires you to run your machine in native UEFI mode (with CSM disabled).

ASUS Enables Resizable BAR Support on First-Generation AMD Ryzen CPUs

When AMD introduced its Smart Access Memory (SAM) technology, it was used as one of the key advertising points for its 5000 series of Ryzen processors based on Zen 3 architecture. At the time of launch, it was believed that only the latest generation of Ryzen processors can support it and only AMD GPUs can see a benefit in performance. However, later on, many of the motherboard makers have been playing with BIOS updates and have found a way to enable resizable BAR, the technology used for SAM, on non-AMD platforms. Today, thanks to the Reddit user Merich98 we have found out that ASUS has enabled resizable BAR support via BIOS update.

The user has used BIOS version 2409, released just a few days ago, on ASUS B450-PLUS motherboard. The feat is no extraordinary because it works on a B450 motherboard, it has been supported for a long time, but rather the feat is impressive because it works with the first generation AMD Ryzen 7 1700 processor. This contradicts the theory that SAM only needs 5000 series AMD Ryzen processors to run. However, the gains were not that great. On average, the average frame rate number has increased by a small +0.839%. This could be attributed to some margin of error, so it seems like SAM is not giving much performance uplift in this case.

BIOSTAR Announces Intel 400 Series Motherboard Support for AMD Smart Access Memory in January 2021

BIOSTAR, a leading brand of motherboards, graphics cards, and storage devices, today announces BIOS updates for their Intel 400 series motherboards to support the AMD Smart Access Memory technology. AMD Smart Access Memory (SAM) allows the CPU to get full access to the GPU memory, users will gain up to 11% in gaming performance. BIOSTAR consumers can now enjoy an extra performance boost with their Intel 400 series motherboards pairing 10th Gen Intel Core processors and AMD Radeon RX 6000 series graphics cards.

BIOSTAR Releases Smart Access Memory Support for AMD 400- and 500-series Chipset Motherboards

BIOSTAR, a leading brand of motherboards, graphics cards, and storage devices today, announces BIOS updates for their AM4 400/500 series motherboards to support the AMD Smart Access Memory technology.

AMD Smart Access Memory (SAM) allows the CPU to get full access to the GPU memory, users will gain up to 11% in gaming performance. BIOSTAR consumers can now enjoy an extra performance boost with their 400/500 series motherboards pairing AMD Ryzen 5000 series processors and Radeon RX 6000 series graphics cards.

AMD Ryzen 3000 and Older Zen Chips Don't Support SAM Due to Hardware Limitation, Intel Chips Since Haswell Support it

AMD Ryzen 3000 "Matisse" processors based on the "Zen 2" microarchitecture, as well as older AMD processors based on "Zen+" and "Zen" microarchitectures, do not support the company's Smart Access Memory (SAM) feature being introduced with Radeon RX 6000 series graphics cards. SAM is essentially a branding of the Resizable Base-Address Register (Resizable-BAR) feature developed by the PCI-SIG; which enables a processor to see a graphics card's entire video memory as a single addressable block, rather than through 256-megabyte apertures. Apparently the PCI-Express root complex of Ryzen 5000 "Vermeer" processors introduce an instruction called full-rate _pdep_u32/64, which is required for resizable-BAR to work.

It gets more interesting—Intel processors have been supporting this feature since the company's 4th Gen Core "Haswell," which introduced it with its 20-lane PCI-Express gen 3.0 root-complex. This means that every Intel processor dating back to 2014 can technically support Resizable-BAR, and it's just a matter of motherboard vendors releasing UEFI firmware updates for their products (i.e. Intel 8-series chipsets and later). AMD extensively advertises SAM as adding a 1-2% performance boost to Radeon RX 6800 series graphics cards. Since this is a PCI-SIG feature, NVIDIA plans to add support for it on some of its GPUs, too. Meanwhile, in addition to AMD 500-series chipsets, even certain Intel 400-series chipset motherboards started receiving Resizable BAR support through firmware updates.

AMD Radeon RX 6800 XT Tested on Z490 Platform With Resizable BAR (AMD's SAM) Enabled

AMD's recently-introduced SAM (Smart Access memory) feature enables users pairing an RX 6000 series graphics card with a Ryzen 5000 series CPU to take advantage of a long-lost PCIe feature in the form of its Resizable Bar. However, AMD currently only markets this technology for that particular component combination, even though the base technology isn't AMD's own, but is rather included in the PCIe specification. It's only a matter of time until NVIDIA enables the feature for its graphics cards, and there shouldn't be any technical problem on enabling it within Intel's platform as well. Now, we have results (coming from ASCII.jp) from an Intel Z490 motherboard (ASUS ROG Maximus XII EXTREME) with firmware 1002, from November 27th, paired with AMD's RX 6800 XT. And SAM does work independently of actual platform.

Paired with an Intel Core i9-10900K, AMD's RX 6800 XT shows performance increases across the board throughout the test games - which are games AMD themselves have confirmed SAM is working with. This means testing was done with Assassin's Creed Valhalla, Forza Horizon 4, Red Dead Redemption 2, and Rainbow Six Siege. The results speak for themselves (SAM results are the top ones in the charts). There are sometimes massive improvements in minimum framerates, considerable gains in average framerates, and almost no change in the maximum framerates reported for these games on this given system. Do note that the chart for Forza Horizon 4 has an error, and the tested resolution is actually 1440p, not 1080p.

ASUS Brings Resizable BAR Support to Intel Z490/H470/B460 Platforms

When AMD introduced its Smart Access Memory technology, everyone was wondering will other GPU and CPU providers, namely Intel and NVIDIA, develop a similar solution to complement their offerings. The SAM technology is just AMD's way of naming PCIe resizable Base Address Register (BAR) technology, which has been present in PCI specifications for years as an optional feature. Why it's emerging now you might wonder. Well, the currently used PCIe revision has reached enough bandwidth on the bus to complement the complex data movement that GPU requires and now supports the use of the wider VRAM frame buffer.

It appears that not only AMD has this technology in its portfolio. ASUS has updated its BIOS firmware for its ROG Maximus XII Apex motherboard based on the Intel Z490 chipset, with some pretty interesting features. According to Tom's Hardware, we have information that the next release of BIOS firmware update 1003 for the ROG Maximus XII Apex motherboard will bring support for resizable BAR, making it a first on an Intel platform. For now, the beta 1002 BIOS supports it, however, a stable version will roll out in BIOS 1003. With the motherboard using PCIe 3.0 standard, a lower-bandwidth revision compared to AMD's platform, it will be interesting to see how resizable BAR is performing once the first tests come.

Update 09:45 am UTC: Chris Wefers, ASUS PR Germany, has announced that resizable BAR will be coming to all ASUS motherboards with Intel Z490/H470/B460 chipset, with alleged 13.37% performance increase in Forza Horizon 4, per ASUSes testing. You can see the test configuration in the image below.

GIGABYTE Releases Resizable BAR Support for AMD 500-series Motherboards via BIOS Updates

GIGABYTE TECHNOLOGY Co. Ltd, a leading manufacturer of motherboards, graphics cards, and hardware solutions, today announces the latest BIOS update on AMD X570、B550 and A520 motherboards for the features of AMD Smart Access Memory and Rage mode. These innovative features enabling a bandwidth boost when the CPU accesses the GPU memory on graphics cards, which enhances and unleashes the ultimate system performance. Now, users with an "AMD Yes" platform on GIGABYTE AMD 500 series motherboards with AMD Ryzen 5000 processors and Radeon RX 6000 series VGA cards, will be able to experience an extra gaming and performance boost.

Through the AMD Smart Access Memory and Rage mode, the CPU has access to the GPU memory. This access unlocks the limited bandwidth to full bandwidth when running 4K gaming. By accessing the GDDR6 GPU memory more rapidly on AMD 500 series motherboards paired with Ryzen 5000 series processors and Radeon RX 6000 series VGA cards, CPU's operating performance and gaming performance are both improved. Based on results of gaming tests with Smart Access Memory and Rage Mode enabled, the 1080P gaming improved by 17%, and a performance increase of 10% was unlocked on 2K and 4K resolutions.

AMD Radeon Smart Access Memory Coming to 400 Series Motherboards

AMD announced Radeon Smart Access Memory (SAM) alongside the RX 6800 series as a feature to increase video memory available to the CPU. SAM is AMD's implementation of the resizable BAR feature found in the PCI Express specification. AMD Smart Access Memory is only available when using an AMD Ryzen 5000 series process and AMD Radeon RX 6800 series graphics card on a compatible motherboard. The feature was initially advertised as a 500 series motherboard exclusive feature but AMD has recently released the new AGESA v2 1.1.0.0 update which should enable support for SAM on B450 and X470 motherboards with a BIOS update.

NVIDIA is Working on Technology Similar to AMD's Smart Access Memory

AMD's Smart Access Memory (SAM) is a new technology that AMD decided to launch with its Ryzen 5000 series CPUs and Radeon RX 6000 series GPUs. The technology aims to solve the problem where a CPU can only access a fraction of GPU VRAM at once, making some bottlenecks in the system. By utilizing the bandwidth of PCIe, the SAM expands its data channels and uses all the speed that the PCIe connection offers. However, it appears that AMD might not be the only company offering such technology. Thanks to Gamer's Nexus, they got a reply from NVIDIA regarding a technology similar to AMD's SAM.

NVIDIA responded that: "The capability for resizable BAR is part of the PCI Express spec. NVIDIA hardware supports this functionality and will enable it on Ampere GPUs through future software updates. We have it working internally and are seeing similar performance results." And indeed, it has been a part of the PCIe specification since 2008. This document dating to 2008 says that "This optional ECN adds a capability for Functions with BARs to report various options for sizes of their memory mapped resources that will operate properly. Also added is an ability for software to program the size to configure the BAR to." Every PCIe compatible device can enable it with the driver update through the software.
