XFX RX 480 XXX GTR Review

   -   


XFX RX 480 XXX GTR Testing:

Finding out just how much gaming FPS performance the XFX RX 480 GTR can deliver will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of a range of capabilities to show where each card falls on the performance ladder. The games used are some of today's newest and most popular titles, which should be able to provide an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustments will be made to the respective control panels during the testing to approximate the performance the end user can expect with a stock driver installation. I will be testing the cards at their stock speeds to see how they stack up and will test each one to find the maximum stable overclock. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. Resolutions of 1920 x 1080, 2560 x 1440, and 3840 x 2160 will be used.

Overclocking:

  • XFX RX 480 GTR: 1383MHz Core, 2204MHz Memory

As the aftermarket has built overclocking and tuning utilities that can overclock AMD's Polaris 10 architecture, you now have options on which tool you can use instead of being stuck with AMD's own Global Wattman tool in the AMD driver control panel. I was able to use both AMD's Global Wattman and MSI's Afterburner tuning tool to overclock the XFX RX 480 GTR. Unlike the last RX 480 I looked at, the same overclock was reached using both tools. AMD's Global Wattman tool is a bit more complex to use, but is fully capable of giving you a great overclock on your hardware. I was able to bump the core clock memory speed up to 1383MHz from the factory boost clock of 1288MHz by increasing the fan speed to 100%, bumping the voltage up to 1150mv, setting the power limit to the maximum setting, and the target temperature to my ambient room temperature. This would give me the best shot at maximizing the core clock speed. I did find that this card did not throttle the core clock speed when the power limit and target temperature settings were at the correct values. Bumping the memory clock speed up required bumping the voltage up to 1100mv and increasing the speed until I hit a wall at 2204MHz. Once the limits were reached, I found the card to be stable at these clock speeds throughout my gaming tests and a couple of extended BF4 sessions. Ultimately, the final overclocking margin was +95MHz or +7.5% on the GCN core, and an increase of 204MHz or 10.2% over the as-delivered memory clock speed of 2000MHz. Fairly typical of what you can expect from a Polaris core and Samsung GDDR5 memory.


 

Maximum Clock Speeds:

Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for thirty minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were re-run until they passed a full hour of testing.
