Diamond Boost Radeon R9 270X 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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 
 

 

At stock speeds the Diamond R9 270X is the second most efficient card in the comparison field. This carries over to the load testing where the Diamond R9 270X has the lowest power consumption under load. When overclocked, the Diamond still is the least power hungry card. Unfortunately when the card is overclocked, it never slows down to idle speeds resulting in a higher average power consumption at idle.
