XFX R9 290X Double Dissipation 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
The results I saw in the power consumption testing show that, at stock speeds, the XFX R9 290X DD is more efficient than the reference design. Slapping some voltage to the XFX R9 290X caused the load power consumption to spike up and over the reference design, while still being more efficient at idle.
