Compute time ratio should be 3:4, assuming the FMA is the only relevant bottleneck.

Not sure if I trust my math, but the implication seems to be that the FMA consumes 47% of total energy with AVX512 and 40% of total energy with AVX2. If "everything else" includes DRAM, disk, power supplies, etc., that result doesn't seem outrageous.
