> Writing efficient code with 512-bit registers is troublesome when there are only 32 of them. And the orthogonality of the instruction sets was and is insufficient. The peak was 128-bit. I will say that again: The peak was 128-bit. Instead of goofing around with 512-bit units, there should have been more 128-bit units. Or better yet: More SIMD registers. In 128-bit SSE2 mode there are only 16. Give me 32 and I will be happy. A good name will be Mega-SSE2. Why would wider SIMD require more registers?
