By most definitions, AMD’s Radeon HD 6900 graphics cards are powerful, but for those who are looking to push huge resolutions, a little more oomph might be desired. That’s where multi-GPU configurations come in, and to see what AMD’s latest are capable of, we’ve tested out both the HD 6950 and HD 6970 in CrossFireX.
Although we generally shun automated gaming benchmarks, we do like to run at least one to see how our GPUs scale when used in a ‘timedemo’-type scenario. Futuremark’s 3DMark 11 is without question the best such test on the market, and it’s a joy to use, and watch. The folks at Futuremark are experts in what they do, and they really know how to push that hardware of yours to its limit.
Similar to a real game, 3DMark 11 offers many configuration options, although many (including us) prefer to stick to the profiles which include Performance, and Extreme. Depending on which one you choose, the graphic options are tweaked accordingly, as well as the resolution. As you’d expect, the better the profile, the more intensive the test. The benchmark doesn’t natively support 2560×1600, so to benchmark with that, we choose the Extreme profile and simply change the resolution.
I’m not the biggest fan of synthetic benchmarks, but 3DMark does a good job of giving us theoretical performance, and in the case of our CrossFireX configurations here, we do see nearly perfect 100% increases.
