NVIDIA GeForce GTX 1070 Founders Edition 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 that the GTX 1070 Founders Edition delivers show that the three heat pipe / aluminum fin array-based cooling does an impressive job of keeping the thermals in check. The lower TDP and CUDA core count on this Pascal architecture card allow the cooling to improve over the results of the GTX 1080 Founders Edition. Much like I saw with the GTX 1080, the GTX 1070 has a specific profile that ramps the fan up as the temperatures start peaking. The noise penalty is much the same as I saw with the Maxwell-based "reference" cards. To expand on that, it's not much of a penalty until you ramp the fan speed up to 100% when the fan is audible, but not oppressively noisy.

If you have followed the power consumption ratings and what each previous generations TDP rating were, you have seen that power consumption targets keep dropping. In fact, NVIDIA has made reducing the power demands of each new architecture a priority. It's not just a buzz word, but a firm commitment to making each generation as power efficient as possible. With Pascal, NVIDIA has done this again. Looking at the power consumption results of the GTX 1070, it is using less power than the GTX 970 under load.
