CPU Scaling - Core i7 9xx
We recorded all the GPU results using a Core i7 processor clocked at 3.70GHz, but does anything happen if we change the clock frequency? Using the GeForce GTX 480 for this test, we found that there was still quite a bit of headroom in the i7 at 1920x1200, which is not surprising given our previous results.
Increasing the processor's frequency from 2.0GHz to 4.0GHz (in 200MHz steps) greatly affected performance, jumping from 27fps through 52fps. Clearly, Civilization V is very CPU dependent as we rarely see such varying results on a game when using such a powerful desktop processor.
