Sapphire HD 7790 Dual-X OC Testing:

Power consumption of the system will be measured at both idle and loaded states, taking into account the peak voltage of the system with each video card installed. I will use Unigine's Heaven Benchmark version 4.0 to put a load onto the GPU using the settings below. A 15-minute load test will be used to heat up the GPU, with the highest measured temperature recorded as the result. The idle results will be measured after 15 minutes of inactivity on the system. With dual-GPU setups, the two core temperatures will be averaged.

Settings

  • Unigine 4.0 Heaven Benchmark
  • 1920x1080 Resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts

 

 

 

 

 

 

 

 

 

 

 

 

When comparing the results to the Sapphire HD 7790 Dual-X, it's clear AMD has done its work on the power consumption curves. The second generation of AMD's Power Tune technology is able to more efficiently manage the power states to allow higher clock speeds overall. Compared to the GTX 650Ti, the HD 7790 Dual-X delivers roughly the same power draw at stock speeds but is almost 20 watts lower when overclocked.
