Phoronix: AMD Ryzen 5000 Series (Zen 3) Linux Expectations - Should Be Good But No "Znver3" Compiler Yet

Today perhaps will be the most interesting day since the start of the pandemic... It's finally the day where AMD Zen 3 desktop CPUs are expected to be revealed in just about one hour's time! Stay tuned, but before that virtual event, here is a word on the Linux prospects and support for these upcoming AMD CPUs...

The one unfortunate area that isn't yet addressed for the Zen 3 support is on the compiler side. AMD has yet to provide any public patches for bringing up Zen 3 with the new znver3 target for the GCC or LLVM Clang compilers.

Probably znver2 will do just fine. I'm wondering, though, what -march=native would do.

phoronix Michael, are you allowed to reveal whether AMD have sent you, or will send you, any CPU for a future review?

AFAIK no Zen 3 reviewers kits were sent out yet. But yes AFAIK will be receiving it like usual.

Prediction. Zen 3 will be a yawner.

There will also be a new 14nm++ Intel Rocket Lake S desktop chip: https://medium.com/intel-tech/intels...e-83677833be7f

Good timing. My youngest daughter wants to upgrade her Gaming-Rig for Christmas Wonder what I'll choose

Probably the same what it would if you had any other unrecognized CPUID. And that's easy to test, isn't it... just remove all the modern cpuid entries from gcc and try.

no ideia they don't put cpu temp patches with linux 5.9 since it come before or almost before the lunch of this news cpu, but ok it will arrive in the next lts kernel at least

znver2 might be really sufficent up to now - it seems that zen 3 is a highly opzimized and almost completly restructured zen 2 so afaik instructionset etc is the same.
