PowerColor Devil R9 270X Review


Powercolor Devil R9 270X Testing:

Testing of Powercolors latest edition to the Devil family the Devil R9 270X 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 first test the cards at stock speeds, and then overclocked to see the effects of an increase in clock speed. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. The NVIDIA comparison cards will be using the 330.58 drivers while AMD-based cards will be using the Catalyst 13.11 beta drivers with the R9 290X running 13.11 Beta 8. The GTX 780 Ti will use the launch driver 331.70. The results generated in my testing were reached by utilizing the latest FCAT tools to illustrate the true picture of the gaming experience. To do so will require a second PC setup to capture the data stream generated by the compared video cards. We have tested the R9 290X in Uber mode to eliminate the clock speed inconsistencies we found while running the card in "Quiet" mode to show the best case scenario for this architecture.

  • Powercolor Devil HD R9 270X : Core 1223MHz, Memory 1592MHz

When I looked at the PowerColor Devil HD 7870 I found that the core really would stretch its legs once you started adding voltage to the mix. Unfortunately the only way to see any boost at all was by increasing the power limits to +20. Using that adjustment as a baseline I adjusted the fan speed to 100% to keep the components including the core, memory, and 7+1+1 phase power system cool to maximize the clock speed potential using the installed cooling solution. By using this method I was able to gain an additional 43Mhz over the rated boost clock speed of 1180Mhz. Kind of a disappointment when you see just what the architecture can do. However that disappointment in the core clock speed is tempered with the massive boost in memory clock speed that helps offset the performance deficit. A gain of 192Mhz in memory clock speed does help drive performance but not as much as core clock speed. Right from the factory Powercolor put a big tune on this card to allow it to perform at a level above the competition. By doing so they did not leave a lot of meat on the bone for the enthusiast. At least with the core clock speed. Once we get some voltage tuning ability on this one we should see the card spread its Devlish wings.


Maximum Clock Speeds:

Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for 30 minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were rerun until they passed a full hour of testing.
