ASUS R9 280X DirectCU II TOP & R9 270 DirectCU II OC 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.
- Unigine 4.0 Heaven Benchmark
- 1920x1080 resolution
- 8x AA
- 15-minute load test
- 15-minute idle test
- Measurement is in watts
Not wholly unexpected, the R9 270 Direct CU II OC does well in the power consumption tests and is the most power friendly card in the comparison field. The ASUS R9 280X DirectCU II TOP at idle is the card that uses the most power even after a fifteen-minute idle period. However, when you look at the load results, it redeems itself by using significantly less power than the Sapphire R9 280X Toxic.
