By coincidence I started a new blog a few days ago and my first article is about the SIMD Instructions Considered Harmful post from a power efficiency perspective... maybe I should post it separately on HN? :) https://massivebottleneck.com/2019/02/17/vector-vs-simd-dynamic-power-efficiency/ https://massivebottleneck.com/2019/02/17/vector-vs-simd-dyna... I think I'm kinda explaining how it's similar (and different) to what modern GPUs do but I'm not sure I understand what you mean by "wouldn't we be able to process 16 of them at the same time" - do you mean a throughput of 16/clock, or just that 16 are "in flight" through the pipeline with a throughput of 4/clock? I'm not sure I'm clear enough about it for those without a GPU HW background. If it's not clear I'm happy to write down a more detailed explanation here!
