AMD Radeon R9 285 GPU Review: Tonga Arrives
Power Consumption and Noise
Before bringing this article to a close, we'd like to cover a few final data points--namely, power consumption, temperatures, 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.

The Radeon R9 285 ended up being one of the more power-efficient cards we tested. At idle, the Radeon R9 285 consumed the least power of the bunch. And under load, despite offering better overall performance than the GeForce GTX 760, it consumed somewhat less power.
In terms of noise, the Sapphire Radeon R9 285 Dual-X was one of the quieter cards we've tested. We don't know how reference Radeon R9 285 cards will sound because we don't have one, but the custom model we tested was darn near silent.
