Testing:

Power consumption of the system will be measured at both idle and loaded states, taking into account the peak wattage of the entire system with each video card installed. I will use Unigine's Heaven Benchmark version 3.0 to put a load onto the GPU using the settings below. A 15-minute load test will be used to simulate maximum load with the highest measured wattage value recorded as the result. The idle results will measured as the lowest wattage value recorded with no activity on the system.

Settings

  • Unigine 3.0 Heaven Benchmark
  • 1920x1080 Resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts

 

 

 

 

 

 

 

 

 

 

 
 

 

If the HD 7770 Vapor-X didn't already have cooling in the bag, it sure took it on the power usage challenge. Though the high end cards it is compared to are expected to have higher usage, the fact that the 7770 showed at least half the use shows good measure.
