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.
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.
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.
Rounding off our performance here, the CrossFireX configurations deliver quite nicely. AMD’s HD 6800 series boosted up tessellation performance a fair bit, and in CrossFireX, we managed to see extremely nice framerates even at 2560×1600.
