Power consumption
We measured system power consumption, sans monitor and speakers, at the wall outlet using a Watts Up power meter. Power consumption was measured at idle and under a load consisting of a multi-threaded Cinebench 9.5 render running in parallel with Guild Wars. Our usual graphics load, the "rthdribl" high dynamic range lighting demo, wouldn't run on the G965 Express.

Somewhat surprisingly, the AMD platforms have markedly lower idle power consumption. The Core 2 Duo E6400 can only drop its default 7x multiplier to a minimum of 6x through either the C1E halt state or SpeedStep, so the chip's actual clock speed doesn't fall all that much at idle.

However, when we crank up our system load, the G965 Express platform manages lower power consumption than any of the other chipsets.
