PowerColor R9 285 Turbo Duo 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 Heaven Benchmark version 4.0 to put a load onto the GPU using the settings below. A fifteen-minute load test will be used to heat up the GPU, with the highest power usage recorded as the final result. The idle results will be measured after fifteen minutes of inactivity on the system with the lowest recorded power usage as the final result.

Settings

  • Unigine 4.0 Heaven Benchmark
  • 1920x1080 resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 
 

 

Energy efficiency is one of the targets with the R9 285 and in my testing that bares out with the lowest power consumption at idle both stock and overclocked. Not only that but under load as well. A thinner memory bus with fewer ICs to power up as well as a reduced core count on the die help drive power usage downwards.
