CPUs? AMDs support running a TPM implementation on the PSP which is on-die. Intel has a TPM implementation running on the PCH, and on low-power mobile parts that's on-package with the CPU. ARM SoCs frequently provide a TPM implementation running in Trustzone, which is also on CPU. Some of the latest Ryzen parts implement Pluton, Microsoft's security core, which is typically used to provide a TPM without also doing a bunch of other stuff.
