Testing:

Power Consumption of the system will be measured in both idle states and loaded states and will take 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 used 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

 

 

 

 

 

 

 

 

 

 

   

   

Lower = Better

 

The idle test results both at stock and overclocked speeds show that the power management and Zero Core power reduces power at idle. Under load with no increase in CPU core voltage there was no increase in power consumed.
