I need to acquire a CPU with the RDSEED instructions for testing. As I work through the datasheets for Intel CPU's, it appears that AVX is the latest instruction set called out. See for example, an i5 CPU and an i7 CPU datasheet.
However, I have a MacBook Pro with an i7 with the AVX instruction set, but lacks both RDRAND and RDSSED. So I feel like I'm missing an important detail somewhere.
What instruction set architecture (ISA) is RDRAND and RDSEED part of? Or, what part of the spec should I be looking at to determine if a CPU has RDRAND and RDSEED?
(I realize RDRAND and RDSSED were introduced at different times. I just don't know how to determine a CPU with the feature).
