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.

Unigine Heaven 2.1

While Futuremark is a well-established name where PC benchmarking is concerned, Unigine is just beginning to become exposed to people. The company’s main focus isn’t benchmarks, but rather its cross-platform game engine which it licenses out to other developers, and also its own games, such as a gorgeous post-apocalytic oil strategy game. The company’s benchmarks are simply a by-product of its game engine.

Unigine Heaven 2.1

The biggest reason that the company’s “Heaven” benchmark grew in popularity rather quickly is that both AMD and NVIDIA promoted it for its heavy use of tessellation, a key DirectX 11 feature. Like 3DMark Vantage, the benchmark here is overkill by design, so results here aren’t going to directly correlate with real gameplay. Rather, they showcase which card models can better handle both DX11 and its GPU-bogging features.

The HD 6790 once again takes a rather demanding lead here, and again, at 1080p or higher, the HD 6770 begins to struggle.
