NVIDIA GeForce GTX 1080 Testing:

Temperature Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine Heaven Benchmark Version 4.0, with MSI Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920 x 1080 using 8x AA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a twenty-minute cooldown, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

 

Settings

  • Monitoring with MSI Afterburner
  • Unigine Heaven 4.0 1920 x 1080 8x AA
  • 5-run sequence
  • 20-minute idle duration
  • Temperature measured in degrees Celsius

 

 

 

 

 

 

Power Consumption:

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

 

 

 

 

The cooling results show that NVIDIA maintains the thermals in a pretty narrow envelope when you compare the results of the GTX Titan X and GTX 980 Ti to the GTX 1080. The results were not far off of guestimates when you consider the use of vapor chamber cooling and a card that is clocked much higher with the Pascal architecture. It's good to see this kind of continuity in the cooling department. Noise levels are quite impressive using the old ears. The GTX 1080 does ramp up fairly quickly when under load, but the noise commitment is much like that of the GTX Titan X and GTX 980 Ti.

One of the key targets for NVIDIA over the past few generations has been to reduce the power consumption of its architecture after taking a lot of heat on the Fermi launch for both the power and thermal results. As you can see in the results, NVIDIA has hit the mark through Kepler and Maxwell, and now have knocked power consumption to new lows with Pascal.
