XFX R9 380X DD XXX OC Review


XFX R9 380X DD XXX OC Testing:

Finding out the amount of FPS performance delivered by XFX's R9 380X 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 will be used. NVIDIA's 359.00 and AMD's 15.11.1 driver packages will be used with each respective card.


Testing Setup:

Comparison Video Cards:




  • XFX R9 380X : Core 1075MHz, Memory 1550MHz


Getting the most out of any video card is going to include overclocking it. Fortunately, video card manufacturers get this and leave us some head room, and even get in on the act with factory Boost clock speeds on top of the base core speed. XFX's R9 380X is delivered with a baseline clock frequency on the core of 990MHz and a memory clock speed of 1425MHz. At 990MHz, the core clock speed of this card gets a small boost from the factory of 20MHz. In my testing I was able to bump up the core clock by 85MHz and the GDDR5 memory by 125MHz, boosting performance across the board. Albeit at different rates. To get to this result I used Afterburner to increase the power limit slightly and bumped up the clock speed until I was getting failures in my stability testing. At this point I would back off the clock speed until it was stable. After that I move to the memory and find the maximum clock speed using the same method.

Once the final clock speeds were locked in, I was able to successfully pass all of my stability testing and found the core clock speed to be stable at 1075MHz after 30 minutes of Heaven 4.0. The 1075/1550MHz clock speeds were stable enough to pass all of my game testing without failures. Overall, we are looking at clock speed bumps of less than 10% on both the memory and core. But when you get down to it, clock speed equals FPS performance when all else is equal.


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.
