HD 7970 3GB DirectCU II 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 2.5 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 3.0 Heaven Benchmark
- 1920x1200 Resolution
- 8x AA
- 15-minute load test
- 15-minute idle test
- Measurement is in watts
What ASUS's cooling solution was able to accomplish in terms of cooling, the 12-phase DIGI+ VRM and Super Alloy Power design components was able to pull off on the power efficiency side of the fence. Across the board, ASUS's design outperforms the Sapphire and reference designs.
