The Perf value stays at P0, but I notice that the power usage declines
from 139W to 103W, then levels out at about 120W. Cap is at 250W.
Temperature never changes from 82C.

It's still not clear to me that we actually have an identical software
environment to what Adrian has. But I admit it looks more like hardware....
