It’s not often that we see a new graphics card get released that’s no different than its predecessor, but with the Radeon HD 6770, that’s just the case. We’re already familiar with HD 5770 performance, but let’s take a look at how this $140 card compares to its similarly-priced competition, including the recently-launched HD 6790.
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.
According to 3DMark 11, the HD 6770 performs best at modest resolutions, with 1080p proving to be a bit much (even with the HD 6790 that’s the case).
