Lowest Prices

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 MSI Kombuster to load the GPU for a 15-minute test and use the peak load of the system as my result for the maximum load. The idle results will be measured after 15 minutes of inactivity on the system. For load testing the GTX 500 series, I will once again use Crysis Warhead run at 2560x1600 using the Gamer setting with 8xAA looping the Avalanche benchmark scenario.

Settings

  • Crysis Warhead Avalance Demo
  • 1920x1200 Resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts

 

 

 

 

 

 

 

 

 

 

   

   

Lower = Better

 

The power consumption numbers delivered by the PowerColor HD 6990 LCS are lower than the GTX 590 and the reference HD 6990 OC in all cases. The lack of a cooling fan spooling up to 4000 RPM or better shows as a 30 watt drop in power consumption under an overclocked and overvolted graphics load.
