NVIDIA GeForce GTX 980 Ti 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 Heaven Benchmark version 4.0 to put a load onto the GPU using the settings below. A fifteen-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 fifteen minutes of inactivity on the system with the lowest recorded power usage as the final result.

Settings

  • Unigine 4.0 Heaven Benchmark
  • 1920x1080 resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 
 

 

Much like the GTX Titan X, the GTX 980 Ti is a bit more frugal when pulling power from the mains, using 11 watts less under load than the GTX 780 Ti at stock speeds. When overclocked and over volted, the big GM200 core is using a bit more juice to reach the overclocked speeds on the memory and CUDA cores. Capping the over voltage and reducing clock speeds 30MHz would improve both the power consumption and thermal results. Even pushing the voltage limits, the GTX 980 Ti is using less current than the R9 290X both at stock and overclocked settings.
