AMD Smart Access Memory Enabled on Intel Z490 Motherboard, Noticeable Performance Gains With Radeon RX 6800 XT

Several motherboard makers have started adding support for AMD'southward Smart Access Memory tech on Radeon RX 6800 XT & RX 6800 graphics cards to the Intel-based 400-serial motherboards. ASUS and MSI are the first to allow back up for SAM with ASRock and Gigabyte quickly working on getting their own support out as well. Japanese outlet, ASCII, has posted the starting time benchmarks of how well the feature performs on the Intel platform, showing a noticeable operation improvement.

AMD Smart Access Memory Tested & Benchmarked on Intel 400-Serial (Z490) Motherboard With Radeon RX 6800 XT, Shows Up To 16% Gains In Performance

AMD'southward Smart Access Memory technology which is a fancy proper noun for BAR (Base Address Register)  will not crave users to invest in a PCIe Gen 4 platform equally it will be supported by PCIe Gen 3 too. Based on what nosotros know so far, BAR substantially defines how much discrete GPU retentiveness space tin be mapped and today's PCs are typically limited to 256 MB of mapped retentiveness. AMD claims that with SAM (Smart Access Retention), they tin can access all of the GPU retentivity, removing bottlenecks to allow for faster functioning.

AMD officially only mentioned that SAM (Smart Access Memory) would exist supported by its Ryzen 5000 CPUs and the respective 500-series chipset based motherboards. Withal, board makers non only enabled support on AMD'south 400-series motherboards but are also adding support to Intel's 400 serial motherboards such as the Z490 variant tested here.

The platform used for testing included the ASUS ROG Maximus XII Extreme motherboard which was running the latest 1002 BIOS which adds support for AMD SAM (Smart Admission Memory) on it. The Intel Cadre i9-10900K CPU was used along with the Radeon RX 6800 XT graphics carte du jour to see if the feature could be enabled and any performance gains tin be seen on an Intel platform with the feature enabled. To enable the characteristic, you have to access the BIOS and navigate to the 'Advanced' folio. The characteristic is set to Disabled by default merely has to be ready to Auto to get it to a working state.

After booting in the PC and opening the graphics carte du jour in the device managing director, y'all can come across that the GPU appears with a 'Big Memory Range' equally indicated past its range address of '0000004000000000 to 00000043FFFFFFFF'.

AMD Smart Access Memory Performance Benchmarks With Intel Z490 & Radeon RX 6800 XT

Coming to the functioning benchmarks, a total of four titles were tested which include Assassins Creed: Valhalla, Forza Horizon 4, Reddish Expressionless Redemption two, and Rainbow 6 Siege. Offset up, we have Assassinator's Creed Valhalla which was tested at 1080p resolution at the high quality preset. The GPU sees a 14% gain in average and a 13% gain in minimum (1%) FPS numbers which is a groovy kickoff for the characteristic on an Intel platform.

Moving on, we have Forza Horizon 4 which was tested at both 1440p and 1080p resolutions. Here at 1080p, the GPU sees a 19% average and a twenty% proceeds in minimum FPS numbers. At 1440p, the RX 6800 XT gains fall downward to 16% average and 17% minimum which indicates a CPU bottleneck at the lower resolution. As yous increase the resolution, the CPU clogging is reduced and the GPU is the primary determinant of performance. With that said, 4K should as well see a double-digit gain in GPU performance at 4K in Forza Horizon 4.

AMD's Smart Access Memory intends to exercise simply that by removing CPU overhead and offering college-performance. Next upward, nosotros have Red Dead Redemption ii which is ane of the well-nigh demanding titles released to date by Rockstar. The title was tested at the highest preset at the 1080p resolution and ASCII saw gains of 8% on average but a huge 2.8X improvement in the minimum result. ASCII reports that they tested the title 3 times and saw the same improvement every time the test was run.

Lastly, nosotros accept Rainbow Six Siege which was tested at 1080p on the highest quality preset. The Intel platform saw a 1% gain on average just in one case once more, a marked improvement in the minimum FPS of 12% compared to SAM turned off. While we don't expect double-digit gains in all games, one thing is assured that Intel users would meet smoother gameplay equally a result of SAM since information technology boosts the minimum FPS figures, reducing the CPU overhead and allowing for faster FPS performance.

While nosotros don't look double-digit gains in all games, one affair is assured that Intel users would see smoother gameplay as a result of SAM since information technology boosts the minimum FPS figures, reducing the CPU overhead and allowing for faster FPS performance. This gratuitous performance heave would be variable throughout the games and applications being tested merely it'south definitely a huge deal considering a 10% leap is quite meaning. NVIDIA is too working on its own BAR (Smart Access Memory) technology which will be supported across AMD and NVIDIA platforms. NVIDIA expects to release it subsequently through a software update.

Rainbox 6 Siege (Highest) 1080p	279	312	112%	611	620	101%	443	441	100%

Update: ASRock has also enabled the AMD Smart Access Retention characteristic on its Z490 motherboard and calling it CAM (Clever Access Retentivity) inside its Z490 motherboards. With a Core i7-10700K & Radeon RX 6800 XT running on the Z490 Taichi motherboard, gains of up to 12% were seen.

Board was running the latest BIOS which enables back up for the feature allowing for higher performance as can exist seen below:

MSI Confirms Its Own Smart Access Retentiveness Support Coming To Intel Z490, H470 & B460 Motherboards

Meanwhile, MSI has appear in a press release that it is bringing a BIOS update to enable AMD Smart Access Memory support on its own 400-series motherboards. The initial plan is to support Z490 motherboards at the beginning of December and so we tin look the BIOS updates to curl out inside a few days. This would be followed past partial support for B460 and H410 motherboards & finally, nosotros can await a full listing of B460 and H410 motherboards to be supported past the end of the month.

MSI showcased a running example of its Z490 GODLIKE motherboard allowing for the 'Big Memory Range' inside the device hardware panel when running a Radeon RX 6800 graphics card.

Unfortunately, MSI has to remove the press release since it too listed down the unreleased Intel Rocket Lake CPU, presumably the Core i9-11900K. The CPU was shown running at a base clock of 3.forty GHz and a boost clock of 4.three GHz which definitely aren't final clock speeds. Other specs such as eight cores, xvi threads, 16 MB of L3 cache, and a TDP of 125W were also spotted.
