Basically these guys are working on a new approach to PC game benchamarking.

By considering the time required to render each and every frame of a gameplay session and finding ways to quantify the slowdowns, we figured we could provide a more accurate sense of true gaming performance—not just the ability to crank out lots of frames for high averages, but the more crucial ability to deliver frames on time consistently.
The results do not change they are s we would expect with Intel on top but surely that emans their testing method works?
