Digging into the details, AVX-VNNI was a game-changer first introduced by Intel with its Alder Lake CPU back in 2021. Standing for Vector Neural Network Instructions, it's a big deal in our AI-centric world today. The difference between AVX-VNNI and its big brother, AVX512-VNNI. Although they share some common ground in functionality, AVX512-VNNI pulls ahead with its 512-bit vectors and EVEX extensions, offering enhanced performance.
With Zen 4 already supporting AVX512-VNNI, the addition of AVX-VNNI to Zen 5 might not seem like a headline at first glance. However, it's an important step, especially for consumer-level processors, reflecting a strategy Intel has also employed in the past.
