Do they cover anything Sapphire Rapids Xeon's don't? I thought they share the same arch (Golden Cove).
According to this [1] wikipedia article, the only feature Sapphire Rapids doesn't support is VP2INTERSECT.

It seems that there are faster alternatives to it

Or Zen 5. :-p
Note that the article mentions using both outputs of the instruction, whereas the emulation is only able to compute one output efficiently.
