Intel's inconsistent SIMD support across its x86 chips seems crazy to me. It's already a hard sell to get programmers to write architecture -specific SIMD code. But Intel then made different subsets of SIMD instructions available on different models. And muddied the terminology by making "AVX-512" be ambiguous. Maybe it was somehow a win in terms of profitability, but it sure made me reluctant to write code to exploit the new instructions.
