Wow, I didn't know that frequency scaling on CPUs was a function of the workload being processed, I thought it was a function of CPU temperature, which would be much less easy to glean meaningful data from (presumably it has a large deal of hysteresis, and you'll have to somehow run a computation millions of times and then run another computation millions of times and compare them). I'm not convinced that I'm wrong.
