PowerColor Radeon HD 7850 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'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 measured temperature recorded as the result. The idle results will be measured after 15 minutes of inactivity on the system. With dual-GPU setups, the two core temperatures will be averaged.
- Unigine 4.0 Heaven Benchmark
- 1920x1080 Resolution
- 8x AA
- 15-minute load test
- 15-minute idle test
- Measurement is in watts
At idle PowerColor's HD 7850 PCS+ delivers power consumption results similar to that of the HD 7950 and HD 7790. Under load it uses almost 20 watts less than GTX 660 at stock speeds. Overvolting and overclocking the Powercolor HD 7850 drives power usage up to the point the power consumption is slightly higher than that of the GTX 660.
