XFX R7 250E Testing:

Testing of XFXs R7 250E 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. A resolution of 1920x1080 will be used. The NVIDIA comparison cards will be using the 340.52 drivers while AMD-based cards will be using the Catalyst 14.7 beta drivers.

Overclocking:

  • XFX R7 250E: Core 950MHz; Memory 1351MHz

 

Getting the most out of this single-slot card from XFX was as simple as bumping the Power Limit up to +20%, adjusting the fan speed to 100%, and bumping the core clock speed up until the card failed my stability testing regimen. I then switched over to the memory and followed the same general guideline to increase the memory speed to a point where the memory speed caused visual clues, such as missing textures. Once the maximum speeds were reached, I backed off 10MHz off each clock speed so the card was not running on the ragged edge during my final stability testing. By using this formula, I was able to reach 950MHz on the core and 1351MHz on the 1GB of GDDR5 memory. After final stability testing using Unigine Heaven 4.0, I ran the Fire Strike test in 3DMark and showed a 500-point boost in performance for my time. You can gain that extra performance for free to use in gaming or when using the GPU in a compute function.

 

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.
