What is the different between AVX-VNNI and AVX512-VNNI ?

[sanbuphy]

Hello! I am using openvino, and then it is stated that the avx512 instruction set is required to get the best results. I found that my computer has AVX-VNNI after lscpu on wsl, but it should be 256 bits wide.

I would like to ask if avx-vnni can have acceleration effect? Then I also saw that other computers have AVX512F, I would like to ask what is the difference between 512F and 512? Can their VNNI be fully utilized? 

If possible, can you give me some more professional information or documents, thank you very much.

As well, you can find further information/documentation in the Intel Resource & Documentation Center (https://www.intel.com/content/www/us/en/resources-documentation/developer.html#panel-top-resources|most-popular)
