Two months ago, Microsoft announced the Pluton security processor and that future AMD, Intel, Qualcomm CPUs will have it. It seems to be for this exact purpose:
> These sophisticated attack techniques target the communication channel between the CPU and TPM, which is typically a bus interface. (...) The Pluton design removes the potential for that communication channel to be attacked by building security directly into the CPU.
M1 powered Macs do this too. Does Intel or AMD make any chips with a TPM built in?
