AVX-512 is on the P-cores only (along with AMX now). The E-cores only support 256-bit vectors.
If you're doing a lot of loading and storing, these E-core chips are probably going to outperform the chips with huge cores because they will be idling a lot. For CPU-bound tasks, the P-cores will win hands down.
