NVIDIA GeForce GTX Titan X Review: Efficient, Powerful
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.
The GeForce GTX Titan X is a major step forward in terms of high-end GPU efficiency. Take note, that despite featuring about a billion additional transistors and a much larger frame buffer, the Titan X consumes similar power to the original Titan, which was also produced on TSMC's 28nm node. The Titan X, of course, also offers much better performance than the original. In comparison to the Radeon R9 290X, the Titan X actually consumes less power, while offering higher performance.
NVIDIA has put significant resources into designing the coolers in its high-end graphics cards, and it has been paying dividends. The GeForce GTX Titan X made a bit more noise than the GTX 980 under load, but its still one of the quietest flagship graphics cards around--it is clearly quieter than the high-end Radeons.
In terms of temperature, our GeForce GTX Titan X sample idled at around 50'C and under load the temperature quickly shot up to its default 83'C target.
