ATI Radeon HD 4770 CrossFire Video Card Review

Power Consumption

For testing power consumption, we took our test system and plugged it into a Seasonic Power Angel. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers, we measured the peak wattage used by the system while running the game S.T.A.L.K.E.R. - Clear Sky at 1280×1024 resolutions with high image quality.

Total System Power Consumption Results

Power Consumption Results: A pair of ATI Radeon HD 4770 graphics cards running CrossFire uses more power at idle than any of the other cards tested, but this makes sense as it is two cards and this setup has the most stream processors. Under gaming load the results look much better as the Radeon HD 4770 CrossFire uses less power than many of the graphics cards that it beat in the benchmarking.
