XFX R9 285 Double Dissipation Black Edition Testing:

Testing XFX's R9 285 Double Disipation Edition card 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 1920x1080, 2560x1440, and 3840x2160 will be used. The GTX 980 will use the latest 344.07 drivers, while the rest of the NVIDIA comparison cards using 340.52. AMD-based cards will be using the Catalyst 14.7 beta drivers, while the R9 285 will be using the beta release driver.

Overclocking:

  • XFX R9 285 Double Dissipation Black Edition:  Core 1136MHz,  Memory 1528MHz

 

Compared to the competitors R9 285 offerings, XFX R9 285 was able to deliver the highest core clock speed out of the three cards I have looked at reaching 1136MHz. As far as the memory overclocking goes, XFX's version comes in second place at 1526MHz. To manage the clock speeds higher than the out-of-the-box clock speeds, you can use any one of the popular video card overclocking utilities. I prefer using MSI's Afterburner tool if a viable alternative is not available. Without any additional voltage control outside of the Power Limit settings, there were no additional tools to gain clock speed other than increasing the Power limit in the Catalyst Control Center to +20% and start moving the sliders and hope for the best. That best was 1136MHz on the core or 161MHz over the baseline 975MHz, a 16+% increase over stock speeds. Where I saw a nice boost on the core the memory, was already pretty close to being tapped out right from the factory. I was only able to squeeze an additional 76MHz out of the GDDR5 memory to help drive some additional memory bandwidth. Not bad overall, but I felt like there should be more available when running the fan speed at 100% to maximize cooling performance. Still, what I could get delivered a 600+ point gain in 3DMark Fire Strike.

 

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.
