AMD Radeon HD 6670 and 6570 Mainstream GPUs

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 how much power our test system was consuming using a power meter. Our goal was to give you all 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 being drawn by the graphics cards alone.

The new Radeon HD 6570 and 6670 proved to be quite power friendly. The card consumed the lease amount of power while both idling and under load. Then again, looking back at the performance numbers, they should consume the least amount of power of the group of the cards tested here.
