SGX and TPM are not the same thing. SGX COMPLIMENTS TPM and is a secure memory space for security keys and other information, whereas TPM is just security hardware equipment built into a CPU or on the motherboard. On the board, it can be broken into, making it worthless for actual security purposes. The BDA used SGX because Intel - the same company behind HDCP - presented it to them during the development talks and cutting edge Intel CPU/GPU hardware was used during the actual development phase, while AMD had no involvement in any of it, despite having their own similar approach. That's why Intel is "the only option". As SGX got busted up shortly after it rolled out to consumers and was used in malware attacks, AMD's own solution became dead-in-the-water, as it wasn't much different from Intel's own and had similar drawbacks. That's why the Pluton processor was developed by Microsoft and will be integrated into AMD mobile/embedded APUs shipping this year, with Intel products to follow later.
