NVIDIA GTX 750 Ti & MSI GTX 750 Gaming 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 power usage recorded as the final result. The idle results will be measured after 15 minutes of inactivity on the system with the lowest recorded power usage as the final result.
- Unigine 4.0 Heaven Benchmark
- 1920x1080 resolution
- 8x AA
- 15-minute load test
- 15-minute idle test
- Measurement is in watts
Across the comparison field you can see the impact of differing architectures and how it relates to the power profiles used. Idle consumption is impacted by the amount of fans and how the card responds to the power saving algorithms employed by each card. Under load the Maxwell-based cards show the lowest power consumption as expected throughout the testing. MSI's GTX 750 Gaming shows a bump of 11 watts under load with 260MHz+ bumps in both the core and memory clock speeds. The GTX 750 Ti shows a six watt jump in power consumption under load when overclocked to equally impressive heights.
