I recall that back in the 90s, besides higher clock speeds, one of the greatest reasons for excitement about a new CPU was instruction set extensions (MMX, 3DNow, etc), which could give outsized performance gains when software was updated to work with them. This latest release from AMD has similar cause for excitement: AVX-512 is more than just larger vectors, it also doubles the number of registers, adds per-lane mask registers, and other enhancements; unlike with Intel processors, there should be no worry of slowing down the clock for the whole processor when using these instructions with larger vectors, and unlike with Intel, we can reasonably expect that every AMD processor from now on will always have these instructions enabled.
