How to purchase the CPU with Intrel Trusted Domain Extension (Intel TDX) support?

[Jinwen]

Are there any available CPUs that support Intel Trusted Domain Extension (Intel TDX)? How can I purchase it? I want to do some experiments on TDX including modifying SEAM module. Thus, cloud services that support TDX cannot satisfy my requirements.

Basically no Sapphire Rapids supports TDX - Emerald Rapids will, see https://github.com/intel/tdx-tools/issues/399
