- fnl 9y agoI'd mostly attribute that to the MKL and their ability to just have to deal with their own instructions. But that's just an "educated guess".
- mattnewton 9y agoProbably also having full time people working in the same company as the hardware guys who's job is to make the hardware look good.
- radarsat1 9y agoI understand the social reasons, but I was wondering more about what compiler does in terms of technical achievements that goes beyond what gcc/clang can successfully generate. Surely this must be something that can be studied empirically.
