Testing:

Testing of the Sapphire HD6870 DiRT 3 Special Edition 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 equal and greater capabilities to show where they fall on the performance ladder. The games used are some of today's newest and most popular titles to give you an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing, with the exception of the 3DMark Vantage testing, where PhysX will be disabled in the NVIDIA control panel, if applicable. I will test the cards at stock speeds, then overclocked in order to see the effects of any increases in clock speed. The cards are placed in order from highest to lowest performing in the graphs to show where the cards fall by comparison. The drivers used are the 11.7 Catalyst drivers for AMD-based cards and the 275.27 for NVIDIA-based cards.

Overclocking:

  • Sapphire HD6870 DiRT 3 Special Edition | GPU - 1040 MHz | Memory - 1250MHz

With so much time from release to perfect the product, I expected great numbers from the card right from the get go. I set right in to it, using Furmark to warm up the card. I then used AMD's de facto Catalyst performance section to begin pushing the clocks up. After I maxed out the Catalyst utility with the card still purring along, I opened up Sapphire's own TriXX overclocking utility. With the TriXX utility, I was able to achieve a new OCC high clock on the 6870 series of 1040MHz on the core. The memory was also able to achieve an impressive clock, coming in at 1250MHz. This should be pretty fun to watch in the testing.

 

 

 

Maximum Clock Speeds:

Testing for the maximum clock speed consists of looping Crysis Warhead and Unigine 2.5 for 30 minutes each to see where the clock speeds will fail when pushed. If the clock speed adjustment fails, then the clock speeds and tests are rerun until they pass the full hour of testing.
