Can you disable cores to get more cache per (actually running) core?

• wmf 7y ago
  Yes. That is what AMD is doing with these chips; e.g. the 32-core version has 64 cores with half disabled and you can disable more if you want.

    I thought the chiplets were binned before getting placed onto the carrier silicon, so they wouldn't need to do the core fusing that Intel does?
    • wmf 7y ago
      There's no carrier silicon and I'm not sure what distinction you're making between binning and fusing. The only way to get 256 MB of cache is to also have 64 cores, the only way to get 192 MB is to have 48, etc.

    Is this possible on first gen Ryzen? I have the 1950x, and I don't see any option to deactivate cores in my BIOS.

      You can do it in Linux https://www.thegeekdiary.com/how-to-enable-disable-cpus-limiting-cpu-count-in-centos-rhel/ https://www.thegeekdiary.com/how-to-enable-disable-cpus-limi... or Windows https://solidlystated.com/software/how-to-disable-a-cpu-core/ https://solidlystated.com/software/how-to-disable-a-cpu-core...

        Wow, I did not realize this was done through `msconfig` on Windows. Thank you very much for the links.
