The Xeon exclusive for this generation is AMX, and I believe Sapphire Rapids has 2 AVX-512 pipelines (sorry, too early to remember the correct term) vs 1 on Alder Lake / Rocket Lake. Disabling it on the consumer chips is related to the heterogenous architecture, since E-cores don't have support. Nobody knows exactly why they decided to fuse it off to disable with E-cores turned off, my guess is because it isn't fully validated/tested (save money) and a very unusual config to start with. Sucks for the 50 people who wanted to run that one emulator, and "save money" is a pretty bad reason for a halo KS product. ECC is available on the consumer chips as of Alder Lake, it's supported with the W680 chipset.
