AMD Radeon R9 380X Review: Fastest GPU Under $250

Power Consumption, Noise, and Temps

Before bringing this article to a close, we'd like to cover a couple of 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 of how much power each configuration used while idling and also while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not the power being drawn by the graphics cards alone.

Total System Power Consumption
Tested at the Outlet


At idle, all of the graphics cards we tested used similar amounts of power, give or take just a few watts. Under load, however, the field really spreads out. The Radeon R9 380X consumed a bit more power than the Radeon R9 285, as you'd expect, and almost hit the mark set by the GeForce GTX 970.

Temperatures and noise were non-issues with the Sapphire Nitro R9 380X we tested. The card idles in the high 40'C range and under load stayed in the mid-70's. And throughout testing, the card remained nice and quiet.  It's not silent, but by no measure would anyone consider the card loud under normal operating conditions.
