Last November, game engine developer Unigine gave all Radeon HD 5000 users a fun tool to push their cards to the limit. Called "Heaven", the benchmark was the first on the market that both utilized DirectX 11 abilities and wasn't based around an actual game. Like Futuremark, Unigine builds its benchmarks with the mindset that what's exhibited will be seen in real games in the years ahead, assuring that it will remain a relevant benchmark for a little while.
Since its launch, both AMD and NVIDIA have been making heavy use of the benchmark in its marketing as a way to stress the importance of tessellation and DirectX 11 in general. NVIDIA has been making heavier use of the demo since this past January, though, since it claims that its GeForce GTX 480 soars through the demo smoother than ATI's Radeon HD 5870. You can find out later this week on our site if that's indeed the case.
