AMD Adrenalin 22.2.2: rBAR driver benchmarked : Test |CUP | Specs |Config

AMD Adrenalin 22.2.2 im Test: Mehr FPS mit rBAR a.k.a. SAM auf bestimmten Ryzen-CPUs

AMD Adrenalin 22.2.2: rBAR driver benchmarked : Test |CUP | Specs |Config – The new Adrenalin 22.2.2 driver officially supports Total War: Warhammer 3. But that’s kind of just a side note. Because AMD also mentions an even higher speed if Resizable BAR or Smart Access Memory (SAM) is used. The promised gains are big. They also show benchmarks from the editors.

These systems should be accelerated

Not all systems with an AMD Radeon that supports SAM should benefit from the new driver. AMD’s release notes for Adrenalin 22.2.2 promise advantages for computers that use a Ryzen processor with an integrated graphics unit, while the image output is done via a dedicated Radeon. A mobile Ryzen processor or a G-model (“APU”) for desktop PCs is therefore required.

So much more performance is promised

AMD’s own benchmarks use a Ryzen 9 5900HX and a Ryzen 7 5800H in combination with a Radeon RX 6800M (test) or Radeon RX 6600M – i.e. gaming notebooks. Depending on the game, the performance should be 10 to 24 percent better than with the Adrenalin 22.2.1 – in both cases SAM was activated.

But do the improvements really only apply to Ryzen CPUs with iGPUs and not to the classic desktop offshoots without a graphics unit? And what if an Intel CPU is installed? The editors used the morning to measure.

The Adrenalin 22.2.2 under test

A Radeon RX 6800 XT was used in combination with Ryzen 9 5950X and Intel Core i9-12900K in Cyberpunk 2077, F1 2021 and Marvel’s Guardians of the Galaxy. In addition, a mobile Ryzen 9 5900HX and a Radeon RX 6800M in the Asus ROG Strix G15 (2021) – the exact combination that AMD mentions in the release notes – had to show whether SAM really got faster. Only 1,920 × 1,080 was chosen as the resolution because Resizable BAR is more effective there than in high resolutions.

Ryzen and Radeon in the notebook: significantly more performance

And indeed: The notebook with the Ryzen 9 5900HX and the Radeon RX 6800M increases significantly with Adrenalin 22.2.2 when SAM is activated. Cyberpunk 2077 delivers 9 percent more average FPS and 4 percent better percentile FPS with the new driver than with the Adrenalin 22.2.1. F1 2021 then increases by 8 and 13 percent and Marvel’s Guardians of the Galaxy by 2 and 10 percent, respectively. The control run with deactivated SAM shows that SAM already had an effect with 22.2.1, so the feature was not only activated now.

Ryzen without iGPU: no advantages

AMD explicitly only mentioned Ryzen with iGPU and benchmarks of the Adrenalin 22.2.2 on the Ryzen 9 5950X with the Radeon RX 6800 XT confirm that there are no increases there. Although F1 2021 and sometimes Guardians of the Galaxy offer slightly more frames per second, this is more in the area of ​​​​measurement inaccuracy, because the improvement is no greater than just one percent at any time. Cyberpunk 2077 doesn’t even respond to the driver at all.

Intel Core and Radeon: no benefits

Even if you have an Intel CPU in your computer, you will not experience a performance boost from the Adrenalin 22.2.2, as with the Ryzen without iGPU. The new driver on the Core i9-12900K and the Radeon RX 6800 XT renders almost as fast as with the Adrenalin 22.2.1. Differences also fall within the range of measurement inaccuracy.

The editors have not yet tested the combination of a G processor for desktop PCs and a Radeon. Feedback from the community on such a configuration as well as other field reports and measured values ​​for the new driver are welcome in the comments.

The Adrenalin 22.2.2 can be downloaded from ComputerBase as usual for Windows 10 and Windows 11.

If you were expecting a test of the new AMD Ryzen 6000 Mobile at this point, the test embargo for which fell today: the sample sent by AMD has not yet reached the editors. Only in the USA were the first devices delivered in good time before the embargo expired.
