I was looking at this CPU and it says the only instruction flag it supports is AVX. But then I found this CPUz analysis and it says it supports SSE among a host of other flags. So what's the deal? Is the Intel site wrong? I can't imagine a CPU only supporting one instruction flag.

AVX processors also support SSE1-4.2.

Why doesn't the Intel website say that?

For most things, everything is a super set of the previous set. It says 64-bit instruction set, but it supports the previous 3 instruction sets. (real, virtual x86, protected mode)

Do you want video cards to say they are DirectX 11.2, 11.1, 11.0, 10.1, 10, 9, ... compatible? That could be pretty tedious!!!

I was going to do just that. I clicked on the contact link and they just have a phone number and address.

In another forum this guy was really adamant about telling me that the only flag it supported was AVX. LMAO!

I think this forum has a lot more better minds and I find more useful information.
