> At a bare minimum, AVX grossly accelerates memcpy and memset operations.
Not necessarily, for large operations and depending on processor generation a simple rep stos/movsb will be simpler (no alignment requirements) and saturate your memory bandwidth just as well as any AVX sequence will with less icache pressure.
