One thing I will point out is that the code in the article is compiled with `-march=native` and `-ffast-math`, meaning that they're really only compiling for the exact same machine they are running on and no other. This seems like it is mainly applicable to places which can easily recompile code for the exact known hardware that they run on, such as HFT and some scientific computing. Places which compile code to distribute for people to run on a variety of processors and platforms (or that require floating point code to be consistent between them), i.e. games and applications, will still be targetting a low end baseline architecture and therefore have a different outcome. I can say that in this space we are only now reaching the point where we can start compiling for AVX2, as we can expect the lowest end-user processor to support it.
