NVIDIA GTX 680 Review

Testing:

Power consumption of the system will be measured at both idle and loaded states, taking into account the peak wattage of the entire system with each video card installed. I will use Unigine's Heaven Benchmark version 3.0 to put a load onto the GPU using the settings below. A 15-minute load test will be used to simulate maximum load with the highest measured wattage value recorded as the result. The idle results will measured as the lowest wattage value recorded with no activity on the system.

Settings

• Unigine 3.0 Heaven Benchmark
• 1920x1080 Resolution
• 8x AA
• 15-minute load test
• 15-minute idle test
• Measurement is in watts

This was a neat test. In all but one scenario, the GTX 680 has the lowest bottom-line power consumption values of all the comparison cards. So, we've seen "the most powerful GPU"; now we just saw "the most efficient GPU".
