The problem is that the downclocking affects more than just the AVX instructions being executed and can last long enough to impair overall system performance. If you could just make each AVX512 instruction take twice the cycles, you'd get the same throughout and energy use per unit real time but not impair the rest of the system. I know it's not really that simple --- but there must be a better way to avoid the AVX throttling problem than the one we've used so far.
