Measurements made by BC confirm my sayings :
Idle power is 44.2W, so including the CPU idle power this latter use at most 55W@3GHz@0.875V, the CB score is 1338pts.
Now keep this voltage as it is but reduce frequency to 1.9GHz, the score will be 850pts and power will be 55 x 19/30 = 34.8W...
So power at 850pts/1.9GHz has been artificialy inflated for some reason.
You can compare two measurements above and deduce the rate of power increasement vs frequency if you want, FI the two lower numbers displayed yield a theorical ratio delta of :
(3/3.2)(0.875/0.95)^2 = 0.795
Taking the higher value wich is 78W delta this yield 62W while the actual measurement is 64W, so theory and practice agree here..
