Huh you seem right. Only the multi-socket Haswell seems to have them (E7-xxxxv3 and E5-26xxv3).
And now Intel re-introduce the SHA instructions in some low-power low-end CPUs, but not for any desktop or single-socket server CPU? What a bizarre case of feature fragmentation. Typical Intel.
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.
