XFX R7790 Black Edition Overclocked 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
In this test we can see how the power curves for comparable HD 7790 cards are optimized with one delivering lower power consumption than the other. In each test the XFX card uses more power than the comparison card.
