I think even Intel is confused about their own extensions at this point. The E7 and E5 Xeons are Haswell systems that slightly speed up SHA-256 and 512 with the introduced BMI2 RORX instruction. As far as I know there are no SHA extensions before Goldmont, as mrb said, and in Cannonlake for non-low-power chips. |
