I spent many hours configuring and updating to a 6.3.3 kernel last night and installed it under bullseye(11) just to run glmark2 against the Radeon RX580. There were only "slight" improvements compared to the closed source nvidia drivers executed under 5.10. The Radeon did show a marginal 17% framerate improvement, but considering it was initially 1/3 the throughput of nvidia, that's just a drop in the bucket.

Without wasting much more effort on experiments I can/will say that for the two cards that are suppose to be comparable (Radeon RX580 and Nvidia 1060) Radeon is left in the dust. ATIs open source drivers don't deliver anywhere near the performance of the NVidia proprietary drivers. This assumes that the cards are in fact comparable, but the gaming kiddies comparisons online made that assertion.

While I hate the NVidia driver model for it's constant need for modification to run with kernel x.y.z, if performance is a concern, it's still the only game in town.

I think NVIDIA have a definite edge with compute, AMD are playing catch up at the moment trying to get a slice of the bitcoin "business". Ironic given that industry is now moving over to FPGA...

I have been playing with the Linux kernel since the 0.9x days, but have since lost my confidence in compiling my own kernel after Linux desktops became competitive (vis a vis Windows). This is above my pay grade.

I'ts been a while for me as well. I used to build my own kernel as a matter policy every time I'd upgrade a distro. The stock distro kernels are always a bit "off" with regard to the features and footprint I'm looking for. ie I prefer a low latentcy desktop with a 1000hz timer. Nothing mroe annoying than a mouse that quits moving because long running diskbound task is blocking the UI. I also prefer to have the /proc/config.gz file present, but that's not a standard config option either.

FWIW, running AMD card under custom 6.3.3 kernel produced some pretty brutal GPU reset crashes when I left it running with an idle but logged in lxce desktop. I went back to the 5.10 kernel to see if the stability resumes.

User-space video drivers, such as mesa, depend on the amdgpu driver embedded in the kernel. Only upgrading the kernel without going through a system-wide holistic procedure can cause user space drivers to turn upside down.

OK. I started to write a long-winded rant about my feelings regarding the in-flux DRI/DRM/mesa infrastructure but why bother?
If it don't work then I have no use for it.

Anyway, I digres. Long live nvidia proprietary drivers...unfortunately.

This "problem" actually underscores the issues of "the rivalry between nvidia and amd", and why the in-kernel amdgpu has changed the prospect of Linux desktops being accepted by the corporate world. Not many Linux old hands actually are aware of this epic change and there is still a long way to go before any corporate adoption of Linux desktops occurs. But at least there is hope; whereas, during the pre-amdgpu days, there was no hope.

AMD's CEO Dr. Lisa Su was already a contributor to the Linux kernel when she was a student at MIT (she received three degrees, BS, MS, and PhD, all in "electrical engineering and computer science", from MIT).

I think Dr. Su realized early on that amd cannot compete against nvidia wrt proprietary drivers in the short run, thus she engaged Linux kernel developers to cooperatively write the amdgpu driver as part of the Linux kernel (at one Linux iteration, about 90% of the Linux kernel update was about the amdgpu driver). To us low-tech business users, this decision has paid handsome dividends, actually elevating Linux desktops to the level of MacOS, surpassing Windows.
