I wanted to add this information to my Cheap AVX-512 monster video as I couldn't get AVX-512 to work on either of my previous G7400 CPUs. The rig itself was fine, but actually neither of those G7400 CPUs had AVX-512 support available as it was already disabled by Intel at the factory which is pretty much the case with all newest Alder Lake CPUs.

Seems that nearly all 2022 batched Alder Lake CPUs have AVX-512 disabled, so you are better off hunting a 2021 batch CPU. Luckily for us Intel left a mark to determine does the CPU support AVX-512 or not, by looking at the IHS. Every CPU that has a halo/circle marking on top of the word Intel on the IHS will have AVX-512 support, and all rectangle/square ish marking CPUs will have it disabled by Intel.

So at least with the Pentiums and other lower end models you can just walk around in a store and look at the processor's IHS from the small peek window and determine if it has AVX-512 or not.
