>Specifically, sustained use of AVX instructions on 256 and 512 bit registers will cost you a chunk of clock frequency even for all, so you have to pass the hurdle of having enough AVX instructions that the downclocking is worth it overall I feel like people who say this have read about it but never actually worked with the instructions. Yes it is true you have to be sure to batch up enough vectorized instructions or you could get an overall slowdown, and that does happen sometimes, but you won't be turning to AVX2 and dealing with all the complications of that if you don't have a lot of work to be done anyway! The net speedup is usually very big
