EDIT: there is still a little something different as i am only getting 5.96 instead of the 6.04 i was getting with the other kernel
I tried those two files.
There are 20% increase of nist5 hash with 10% increase of power consumption.
But for X11, there is only 1-3% increase of hash, with 10% increase of power consumption.

I use 7990, 7970 and 7950.
