But what 100% workload? Is it 100% integer throughput? In which case it'll use a small fraction of the power of a blended integer & float workload. What about AVX-512? Is that considered 100% or beyond 100%? How much RAM is in play? Is it entirely an L1/L2 workload such that memory is never a bottleneck? Or is RAM used and then the CPU isn't really hitting maximum compute throughput? Or is it RAM reads & writes perfectly intermixed with integer & float computations that will always be L1/L2 cache hits, even though literally nothing will ever have that flawless of an execution in terms of power consumption?
With how much of a CPU is dynamically gated & power controlled there is a difference between "maximum theoretical draw" and "maximum a 'real world' 100% load" will hit.
