Using the Phoronix Test Suite with the MONITOR=gpu.temp,sys.power PERFORMANCE_PER_WATT=1 environment variables, I also ran some tests looking at the reported GPU temperature, overall system power consumption (being read with PTS through a USB-based WattsUp power meter), and the calculated performance-per-Watt.

When running Unigine Valley at 1920 x 1080, the Core i7 4770K system with GeForce GTX 650 graphics card had an average power consumption of 126 Watts -- much lower than the 186 Watt average of the HD 5830 or 193 Watts with the GTX 550 Ti. The only graphics card with a lower overall system power consumption was the GT 520.

With the Phoronix Test Suite then automatically determining the performance-per-Watt for the power data captured while running the benchmark, the FPS-per-Watt of the GTX 650 was right in line with the tested Radeon HD 5000/6000/7000 series graphics cards. The performance-per-Watt of the GTX 650 was superior to the GTX 460 and GTX 550 Ti but behind the GTX 680 and Radeon R9 270X.

The MSI GeForce GTX 650 GPU power temperature during the Unigine Valley workload was a comfortable 53 Celsius.
