PowerColor Radeon HD 7790 Turbo Duo 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
PowerColor's HD 7790 Turbo Duo is more efficient than the GTX 650Ti when overclocked yet has trouble delivering the same level of efficiency I saw with Sapphire's card. Under load it uses about five watts more and eleven watts more at idle.
