Does processor Xeon Gold 6248 @2.5G support AVX512_VNNI instruction set?

[User1578037094245524]

I have a PC and processor is ​Xeon Gold 6248 @2.5G. I find it supports AVX512_VNNI instruction set according to the following information.

https://en.wikichip.org/wiki/intel/xeon_gold/6248

But when I test it with CPUID, it shows the processor cannot support AVX512_VNNI.

Does anyone have the exact information about it?

Thanks a lot!

CPUID is a great utility, but sometimes has an incomplete database, so you should not use that as a test.

In this document, you will see that the Gold 6200 series supports VNNI:

Just search for "vnni" on page 10.

​Hello,

Thank you for your support!

I think my processor is supporting AVX512_VNNI according to specification provided by Al H, but when I write a code using VPDPWSSD, the program crash. 

VPDPWSSD zmm0, zmm1, zmm2

Can you give me some advice for AVX512_VNNI instruction?

Thanks
