PowerColor PCS+ R9 380X Myst Testing:

Finding out the amount of FPS performance delivered by PowerColors PCS+ 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.

Overclocking:

  • XFX R9 380X : Core 1126MHz, Memory 1601MHz

 

After putting another R9 380X through its paces, I was a little apprehensive when it came time to overclock PowerColor's PCS+ R9 380X. Those fears were soon dismissed as I started pushing up the core clock speed, as 1100MHz was an easy stretch at full stability. At 1150MHz, it would pass some basic stability tests, but was only good enough for some of the less stressful benches. While 1150MHz would have been a really decent clock speed, I had to back it down to 1126MHz to run all the benches long term. After 30 minutes of looping the Heaven 4 benchmark, 1126MHz was the applied and in use clock speed. Something nice to see is AMD is using variable clock speeds now.

Memory overclocking was just as fruitful, with a final clock speed of 1601MHz or a 126MHz boost over the factory overclocked 1475MHz speed. Boosts of 106MHz on the core and 126MHz on the GDDR5 memory are nothing to sneeze at when you look at the performance increase potential this adds to the FPS bottom line. On a percentage basis, the core clock speed increase is just over 10% on the core and around 8.5% on the 4GB of 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.
