XFX HD6950 1GB Overclocked Edition Review



Testing of the XFX HD 6970 XXX edition will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. These will test the performance against many popular competitors, and comparisons will be made to cards of varying capabilities to show where it falls on the performance ladder. The games used are some of today's newest and most popular titles to provide 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 for NVIDIA-based cards. I will test the card at stock and overclocked speed to see how much additional performance gain is available. The drivers used in this test will be the 260.99 Forceware drivers from NVIDIA for all cards save the GTX 580 and the 11.2 Catalyst drivers for AMD. As previously stated, tests will be conducted at both stock and overclocked settings to gauge performance when an increase in clock speed is applied.


Comparison Cards


Overclocking this guy is done through the widely available MSI Afterburner software, which allows for full control over graphics hardware. It allows core frequency adjustment, voltage tweaking and fan speed adjustments. With the seemingly highly efficient cooler on this card, I should expect to see a good bit of overclockability of out it. With the ability to adjust voltage, this opens up an entirely new world in the limits of overclocking this card, while keeping the temperatures within reason. I was able to get the XFX HD 6950 XXX Edition to hold stable at 1002MHz on the core, and 1570MHz on the memory — all which scaled very well. These results are the fastest AMD card out of the comparison numbers, and had the fastest memory speed of all of the cards! I was very impressed!


Maximum Clock Speeds:

In the past, I had used MSI's Kombuster utility to check for stability coupled with the ability to run through the entire test suite. I have found that some game tests would still fail with this utility, so I have moved to testing with several games at maximum settings through several resolutions to verify the clock speeds that are listed below. Why the change? I have found some cards will play fine at a 4xAA setting, but fail when using 8xAA due to the increased graphics load. If it fails, then the clock speeds and tests are rerun until they pass.
