NVIDIA GTX 670 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

The GTX 670 delivers power numbers to suggest that the 170W usage rating in games is spot on with a delta of 166W at stock speeds and 174W when overclocked.
