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

 

 

 

 

 

 

 

 

 

 

 
 

 

At stock speeds the HD 7970 3GB Vapor-X is fairly frugal by comparison to the Black Edition card. When the clock speeds and applied voltage are increased the temperatures will spike upwards.
