PowerColor R9 290X PCS+ 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
At idle, the PowerColor R9 290X PCS+ is more efficient than the comparison R9 290X cards; one a reference design, one a custom design. Under load at stock speeds, the PowerColor PCS+ uses 13 watts less than the XFX card. Overclocked results are not as rosy due to varying voltage offsets needed to run the number, but in this case the PCS+ uses only two watts more than the reference version from PowerColor.
