I have read papers from Intel that discuss Intel® Software Guard Extensions (Intel® SGX) Support for Dynamic Memory Management Inside an Enclave (also called SGX2). However, I cannot tell whether a specific processor supports SGX2. Intel's official website only gives information about whether a processor supports SGX while no furthter information about the version of SGX is provided. As I am going to purchase a processor supporting SGX2, how am I supposed to do? Any help is highly appreciated.
