Hello, great tutorial :)
I have late suggestion for a tutorial that is 3+ years old: I'd suggest spelling out the acronyms at the very beginning. There's a point in the life of every programmer when there are just way too many acronyms, and you start loosing sight of what is what. AVX = Advanced Vector eXtensions, SSE = Streaming SIMD Extensions, and SIMD = Single Instruction, Multiple Data.
Could not agree more, I was just wondering that about xmm and ymm registers. maybe eXtended memory and wi(Y)de memory? ...
