AMD Radeon HD 7950 Tahiti Pro DirectX 11 GPU Review
Total System Power Consumption
Before bringing this article to a close, we'd like to cover a few final data points--namely power consumption and noise. Throughout all of our benchmarking and testing, we monitored acoustics and tracked how much power our test system was consuming using a power meter. Our goal was to give you an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power drawn by the graphics cards alone.

Quite simply, the Radeon HD 7950's power consumption characteristics were the best of the group. Both idle and load / peak power were below all of the other cards we tested. That wouldn't mean much if the card offered middling performance, but it was the second fastest, single-GPU powered card in the group, finishing behind only the Radeon HD 7970 most of the time, though the GeForce GTX 580 did have its moments.
