Overall, the AMD Radeon R9 270X performance was very good for being a $200 graphics card. Using the Phoronix Test Suite I then ran some tests to measure the power consumption, performance-per-Watt, and GPU power temperature of these graphics cards. With the Phoronix Test Suite all monitoring was done automatically via setting the MONITOR=gpu.temp,sys.power PERFORMANCE_PER_WATT=1 environment variables.

The total AC power draw was measured using a WattsUp USB power meter that was being read by the Phoronix Test Suite. When running Unigine Valley, the system overall with the Radeon R9 270X was consuming an average of 207 Watts and a peak of 214 Watts. The Radeon HD 7950 in the system lead to am average power draw of 223 Watts and the GeForce GTX 680 system power draw was an average of 265 Watts. The Radeon R9 270X in the system had an average power draw comparable to the Radeon HD 6870 and was lower than the Radeon HD 6950.

When calculating the performance-per-Watt automatically via the Phoronix Test Suite with this data, the FPS-per-Watt average was right in line with the Radeon HD 7950 and a tad behind the GeForce GTX 680 performance.

The GPU power temperature while running Unigine Valley was 53.7 Celsius on average for this graphics card -- well below the Radeon HD 7950 and GeForce GTX 680. Gigabyte's cooling solution for the R9 270X was very good and also quite quiet.
