Overclocker reveals how to check Intel Alder Lake CPU for AVX-512 support

Officially, Alder Lake chips don't support AVX-512, but many can still execute workloads based on that instruction set. Some motherboard vendors even allow you to enable support for AVX-512 if a chip supports it. Unfortunately, Intel stopped producing AVX-512 capable Alder Lake chips in March.

Currently, there are Alder Lake chips out there that support AVX-512, while some don't. One way to check for compatibility is by mounting the CPU and attempting to run a benchmark using the instruction set. However, there's an easier way, as shown by Luumi (via VideoCardz).

On the IHS of an Alder Lake processor, you can read the CPU series, the model of the chip, the spec code, and the FPO (finished process order). On top of all that text, there's a marking that differs if a chip supports AVX-512 or not. Chips with a circle icon support AVX-512, while chips with a square icon do not support it.

Eventually, it will be harder to get an early production SKU, as they will be sold on to consumers who may or may not care about AVX-512. With that in mind, if you really need this feature, you may need to do some hunting to find one.

KitGuru says: It is still unclear why Intel removed AVX-512 support at launch, but it isn't something that will impact many people. If it is something you care about, you now know how to spot the difference between a supported and unsupported chip before buying.
