AMD’s GTX 560 Ti Counter-Offensive: Radeon HD 6950 1GB & XFX’s Radeon HD 6870 Black Edition

The Test & Gaming Performance

For our testing we are using both AMD and NVIDIA’s latest drivers where suitable. For AMD this means the 11.1a Hotfix, and for NVIDIA this means the 266.58 drivers for the GTX 400 and 500 series, 266.56 for the new GTX 560 Ti, and 262.99 for the GTX 200 series. Compared to our previous benchmarks NVIDIA Civilization V performance is way up, and SmallLuxGPU performance is up for both AMD and NVIDIA. There are no significant performance improvements elsewhere.

For NVIDIA cards all tests were done with default driver settings unless otherwise noted. As for AMD cards, we are disabling their new AMD Optimized tessellation setting in favor of using application settings (note that this doesn’t actually have a performance impact at this time), everything else is default unless otherwise noted.

For our look at gaming performance we’re going to skip our running commentary at this time. In practice the 1GB 6950 is just as fast as the 2GB 6950 at 1920x1200 and 1680x1050 – the essential resolutions for a $260 card. It’s only at 2560x1600 and Eyefinity resolutions that the 2GB card makes a difference with most games at this time. This is likely to change in the near future, but for the time being –and as you’ll see – there’s little disadvantage to a 1GB 6950 right now.

Meanwhile we’re also including the XFX Radeon HD 6870 Black Edition in these charts. In general it’s around 5% faster than a stock-clocked 6870, which isn’t enough to cut in to the GTX 560 Ti’s 10-15% lead. At $20 less than the GTX 560 Ti this makes it a potential value spoiler, but not a direct competitor.
