Power consumption
Appreciating that gaming performance is, as expected, solid, we're actually more interested in the power consumption, temperatures, and noise.
There's a 20W power-draw increase when going from the reference card to KFA2's. This is a good result considering the extra power the GPU needs to consume when running at faster-than-default frequencies. Tellingly, the consumption is significantly lower than the Gigabyte SOC's, though it can't rival the Radeon HD 6950's.
FurMark exacerbates the power-draw deviation between the GPUs, where the comparison Radeon consumes 45 fewer watts while the also-overclocked Gigabyte requires an additional 65W.
