By itself the TPM is independent of any CPU. However, it's also not very useful (though for Pond's use case, it works).

The TPM gets much more useful when it's integrated with features on the motherboard, BIOS, CPU, northbridge, IOMMU etc. Then you have a full blown TCG-compliant TC environment, which is useful for many things. Actually it was never very useful for DRM - that was only one theoretical possibility that was never implemented and even if it had been, TC is to DRM much as cryptography is to DRM. So the FUD was just that: fear, uncertainty and doubt which probably crippled a highly useful cryptographic security tool for good. One of the more shameful periods of the tech industries history, if you ask me.
