Testing the Sapphire HD 7750 ULTIMATE will consist of running it and the comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance of the video card against many popular competitors. Comparisons will be made to cards of equal and greater capabilities to show where they each fall on the performance ladder, using games that are some of today's newest and most popular titles which will provide an idea of how the cards perform relative to each other.
The system specifications 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. The card will first be tested at stock speeds and then overclocked to see the following effects. The cards will be placed in order from highest to lowest performing in the graphs to show where they fall by comparison. The drivers used are the 11.12 Catalyst drivers for AMD-based cards, with the exception being the new HD 7700 series that have been tested with the latest AMD press release performance driver driver. The 290.53 drivers for NVIDIA-based cards are used for the testing.

To be honest with you, I was a little weary of overclocking the Sapphire HD 7750 ULTIMATE all that much, simply because I wasn't sure of what the passive cooler could actually handle. As it turned out, I wasn't able to use the voltage controls for the HD 7750 ULTIMATE, so the overclock didn't end up affecting temperatures at all. After seeing how well the HD 7770s overclocked, I was hoping that this card would be able to hit a core clock of somewhere in the 900MHz range. So I did what you're absolutely not supposed to do, started there, and was greeted with an instant crash! After rebooting the machine I decided that I would achieve the best overclock, by actually doing it properly. After many increases to both the Core and memory clocks I was able to achieve a fair 879MHz and 1258Mhz clock speeds, respectively. While this isn't the most impressive overclock in the world, it's not to shabby for a card that uses a passive cooler.
Maximum Clock Speeds:
Testing for the maximum clock speed consists of looping Unigine 2.5 for 30 minutes each to see where the clock speeds fails when pushed. If the clock speed adjustment fails, then the clock speeds and tests are rerun until they pass a full hour of testing.
