• Christ. I am so behind on CPU terminology.

    I get tripped up by the families, and the modifiers, and AMD doesn’t help with their naming. Ryzen 5 5600. R 7 5800. R 7 5800H. R 7 5800X. Ryzen 7 7800X3D. Ryzen 7 9800. I know these also fall into different families, which have different capabilities, but then there are things like AVX-512.

    Does something like avx512 show up in the flags of /proc/cpuinfo? I’ve looked at cpu-x; it dumps info like AVX(1, 2) - how does that relate to AVX-512? The Family is also number and not the names AMD uses, like “Summit Ridge” or “Raven Ridge”. Is there a tool to translate this information?

      yes, zen4 is the ryzen 7xxx ans onwards. I think they will change the naming scheme again after the 9xxxs now though.

      In my case my 5xxx cpu shows avx2 (256bit) in /proc/cpuinfo, I assume you will find avx512 there if you have it.

      Also apparently there are mobile and server cpus with 7xxx names that are zen3. It is a mess certainly.
