I’m considering picking up a cheapish laptop for development, with the intent of installing Linux on it. Typically it’ll be Java development or other stuff in docket containers. Is there a best chipset to pick for Linux or are they pretty much identical these days?

    see for instance the microcode for family 19, the Zen3, Zen4 family, the microcode update is:

    Microcode patches in microcode_amd_fam19h.bin:

    • Family=0x19 Model=0x11 Stepping=0x02: Patch=0x0a10123e Length=5568 bytes

    There is only update for 7 CPUs, before this August update, there was only 3 microcode!!! compare this to the number of CPU they have in this family:

    I have a 5600H, family 0x19 and model 0x50, no update, as well as dozens of others AMD cpu.
