Linux 5.16 Has A Nice Performance Gift For AMD Ryzen Laptops With Radeon Graphics

[ryad]

The most exciting part about 5.16+ is the fixes for this laptops sleep system. So many people are suffering from these bugs (a lot of power usage in s3, no ability to use s0ix):

That's awesome news, I have issues like these for a while now on my system. Building a mainline kernel right now and hope for the best Thanks!

Update: Can confirm that the performance has increased in CS:GO. Whereas I had slightly below 60 fps on average with kernel 5.15, mesa 21.3 and the new Vulkan option at 1080p in fps_benchmark.bsp, it now goes up to about 80 fps on average with the 5.16 RC6 kernel. Haven't tried mesa 22 though.

That's not how Linux works. A distribution can't be "designed" for a specific kernel version. Pop OS may not provide prebuilt kernel packages for the latest kernel version, but there is literally nothing stopping you from compiling and installing your own from vanilla sources. Provided you do this correctly it would work absolutely fine

I know, but Pop uses kernelstub, it might have changed recently but its not great for using extra kernels. I might switch to fedora if I hit any limitations

Doesn't the last BIOS update solve it?
It seems the last bios has a Linux new config..

Not for many. Actually there is no guarantee any future BIOS does so far... But the intention is for firmware + 5.16rc to have a fix for most of these sleep issues.

Interestingly, the improvements were also in one benchmark where in the Windows 11 vs. Linux benchmarks the Windows performance was ahead. Not enough to reach parity though.


Unfortunately there are not many benchmarks in common between this article and the Windows vs. Linux article.

Does alleged perf.improvement includes discrete Vega cards?
