MSI RX 480 Gaming X 8G 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 1920x1080 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 thermal results that you see delivered by the Twin Frozr VI-equipped MSI RX 480 Gaming X 8G seem out of character with the potential of the cooling solution at first glance. The Twin Frozr VI cooling solution is designed as a close to or zero noise solution. Taking that into account and knowing that at idle the dual dispersion blade fans are running at zero RPM, as long as the core thermals stay under a 60 °C limit.; once this thermal level is reached the fans start spinning. This means that, for the most part, the card will be dead silent unless you apply a 3D load on the card. Once you apply that 3D load, the card will slowly ramp up the fan speeds once the Polaris core hits 60 °C, driving up the baseline thermal results. If you intervene and crank the fan speeds up or set up your own fan speed profile in Afterburner, you can reduce operating temperatures to levels you can control. Even though I saw higher than expected results at stock speeds, the overclocked and overvolted loaded thermal results are more indicative of what the Twin Frozr VI cooling solution can do.

Power consumption totals for this latest generation of cards from AMD and its partners show that they have done their homework and started reeling in the performance per watt metrics. This card from MSI is delivering power consumption levels close to those delivered by the GTX 1070 for less overall FPS performance.
