Thanks for the suggestion. https://en.wikichip.org/wiki/amd/cpuid also seems to have some good info. Currently we're covering Rome and Castle Peak (`0x31`), and Matisse (`0x71`). We're missing the Xbox series X APU (`0x47`), Renoir (this patch, `0x60`), Lucienne (`0x68`), Matisse (`0x71`), Van Gogh (`0x90`), and Mendocino (`0xA0`).

I'm assuming we just want to cover all of these?
