Le gain de performance du code assembleur utilisant les instructions AVX-512 a atteint 94, 44, 64 et 4.24 fois par rapport \u00e0 l'impl\u00e9mentation de base \u00e9crite en C sans l'utilisation d'instructions SIMD. Dans le code assembleur avec optimisations bas\u00e9es sur les instructions AVX-2, le gain \u00e9tait de 67, 27, 55 et 4.38 fois, respectivement, tandis que sur la base des instructions SSSE3 \u2014 40, 21, 29 et 2.49 fois. Les modifications ont \u00e9t\u00e9 int\u00e9gr\u00e9es dans la biblioth\u00e8que dav1d, qui propose un d\u00e9codeur alternatif pour le format de codage vid\u00e9o AV1. Les instructions AVX-512 sont disponibles dans les processeurs AMD reposant sur les microarchitectures Zen 4 et 5, ainsi que dans les processeurs Intel bas\u00e9s sur des microarchitectures telles que Skylake-X, Ice Lake, Tiger Lake et Rocket Lake.
