How would they detect the difference?

Probably built-in crypto keys signed by Intel/AMD keys.

That would be unfortunate for Infineon who create the majority of TPM chips. Who’s going to be the gatekeeper who decides who can create TPM chips and what’s going to happen when a new manufacturer wants to enter the stage?
