NVIDIA GeForce GTX 780 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
When you compare the idle results it's uncanny how the GTX Titan and GTX 780 share the same power consumption levels. Under load the additional hardware in the GTX Titan's core is drawing more current than that of the GTX 780. When compared to an aftermarket HD 7970 GHz edition card, the GTX 780 is dead even consumption wise at the baseline clock speeds. Overclocked the GTX 780 over volted is using more power than the HD 7970 that does not feature any voltage adjustments (on this card).
