Now onto some power and thermal data recorded by the Phoronix Test Suite via automatically interfacing with the NVIDIA binary driver's NV_CONTROL extension to read the GPU core temperature data and an AC WattsUp USB power meter for real-time sensor monitoring during benchmarking. More of this data is available on OpenBenchmarking.org via 1311217-SO-NVIDIATHE33.

When running the very demanding Unigine Valley benchmark, the GeForce GTX TITAN had an average operating temperature of 79 Celsius from the open-air test system. The peak temperature for the GTX TITAN was 81 Celsius and it started from idle at 63 Celsius. The thermal performance was much better than the Radeon R9 290 and it was right in line with the GK110-based GTX 780 Ti bearing the same cooler.

The average AC power draw of the Core i7 4770K system when running Unigine Valley was 309 Watts, a 364 Watt peak, and a 163 Watt idle.

While the GTX TITAN had lower frame-ratess than the GTX 780 Ti, when calculating it out to performance-per-Watt it was right in line with its GK110 sibling and was leading amongst all the NVIDIA and AMD graphics processors tested.
