XFX R9 390X 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

 

 

 
 

 

Using basically the same core as the R9 290X from XFX running at higher clock speeds, the improvements in the Double Dissipation cooling system are obvious here with nice improvements in both the stock and overclocked load temperatures when you compare the 2XX and 3XX series cards from XFX. At stock speeds the Double Dissipation cooling system is almost dead silent when packed up in the chassis. At 100% fan speeds under load, the card is going to generate more noise as one expects. This card from XFX did not deliver out of the box noise levels when the fan speed gets boosted, but the temperatures do go from middle of the pack to only better than the R9 290X under load. Still, a long term load does tend to increase the thermals.

The power consumption results show that by using the same core the power consumption results do not change that much from the 2XX series to the 3XX series card using the Hawaii/Grenada XT core. At stock speeds you do not see a major increase in power usage, but when overclocked the results scale upwards. To get the most out of the card required bumping up the applied voltage to reach 1170MHz on the core.
