As fare as I can tell, model 0x61 stepping 0x02 is the AMD Ryzen 7000 series, and 0x50 stepping 0x00 is the AMD Ryzen 5000 series, this is the main AMD desktop CPUs from the previous generations.
There is an
amd-ucode-firmwarepackage, but it only contains microcode for servers and outdated microcode for Chromebooks.
The models listed in the amd-ucode repository seems to be more than just servers and old Chrombooks.
That said, I don’t know what the blobs contain. The description in the repo could just be a type of placeholder for the entire 19h family, and it doesn’t actually have microcode for all the listed models.
