Power consumption was measured from the wall socket directly from the computer. Idle was taken after 5 minutes into the Windows desktop and Load was tested emphasizing gaming performance and the video card in Crysis' GPU demo. Cool 'n Quiet was enabled.
The extra memory clock seems to suck up some extra juice as well unfortunately compared to the standard 4890. Overclocking we maxed out at 990MHz for the GPU which was actually slightly below our Gigabyte 4890 and 1.15GHz for the memory. A higher core clock seems to be more effective in increasing the framerate 10-15% than overclocking the GDDR5 memory which may not be saturated by today's games. As mentioned earlier the card does run quieter than the standard 4890 fan and as far as cooling they appeared in our testing to be about even in temperature.
