Power Consumption, Temps, and Noise

We'd like to cover a few final data points before bringing this article to a close. 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 an idea as to how much power each configuration used while idling and 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.

Power Consumption and Operating Temperatures
How low can you go?


The V7900 and V5900 showed two of the lowest fully loaded power consumption results in our comparison group. Only the entry level V4800 offered better results. Specifically, the V7900 used 16% less energy than the V7800 under load, and 8% less in an idle state.



While monitoring operating temps, the V5900 ran the coolest under load at 62 degrees. On the other hand, the V7900 showed similar temperature results as the V7800, at 72 degrees fully loaded and 49 degrees idle.

Also, its worth mentioning the noise levels we experienced using the new FirePro models. We maintained a quiet working environment with both cards. During our load testing with Furmark, neither one created enough noise to make us notice a change in sound levels versus the rest of our system components.
