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 2.5 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 2.5 Heaven Benchmark
  • 1920x1200 Resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts

 

 

 

 

 

 

 

 

 

 

 

 

 

Having looked at the big performance leap between these two HD 7770s and the rest of the performance cards, a direct correlation is shown here in regards to power consumption. The load consumption, even when overclocked, stayed under 200W. You can't say that for the rest of the cards! The more FPS you want will be compensated for by more nickles and dimes on your power bill.
