They also have TPM 2.0. But that isn't the limiting factor anyways.

Nope, they have emulated TPM 2.0 and while it allows the same result, it can take too long in many cases. First gen ryzen has a hardware TPM 1.2

you are right as well however, as the ryzen 2000 chips use a hardware TPM 1.3 Which is hardware 'compatible' according to Microsoft. The difference is the things that need to be made up with general compute on 1.3 hardware is acceptably fast compared to 1.2.
