Power Consumption and Noise

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 just the power being drawn by the graphics cards alone.

Total System Power Consumption
Tested at the Outlet

pow1
The Radeon R9 390's power consumption is right in-line with the 290X. Idle power seems to have been improved slightly, despite the doubling of the memory capacity, but we're only talking a few watts here.

noise
In terms of noise output, the Powercolor PCS+ Radeon R9 390 we tested was slightly quieter than AMD's reference cards, but was nowhere near as quiet as NVIDIA's current offerings.
