Powercolor Devil R9 270X Testing:

Power consumption of the system will be measured at both idle and load states, taking into account the peak voltage of the system with each video card installed. I will use Unigine's Heaven Benchmark version 4.0 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 power usage recorded as the final result. The idle results will be measured after 15 minutes of inactivity on the system with the lowest recorded power usage as the final result.


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

















At idle the Devil R9 270X takes advantage of AMD's latest Zero Core and Power tune technologies. Comparing the old to the new shows that the R9 270X is a bit less efficient at stock speeds, more likely due to the higher boost clock speeds and voltage required to hit the numbers. When voltage is used to boost the clock speed the Devil R9 270X uses less current than the Devil HD 7870.
