Sapphire HD 7790 2GB OC 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
You would expect that powering an additional 1GB of memory would show up in the increased power consumption results. Here we see the 2GB Sapphire card using more power than the Dual-X 1GB version.
