Unigine Heaven Benchmark 2.5 is a DirectX 11 GPU benchmark based on the Unigine engine. This was the first DX 11 benchmark to allow testing of DX 11 features. What sets the Heaven Benchmark apart is the addition of hardware tessellation, available in three modes – Moderate, Normal and Extreme. Although tessellation requires a video card with DirectX 11 support and Windows Vista/7, the Heaven Benchmark also supports DirectX 9, DirectX 10, DirectX 11 and OpenGL 4.0. Visually, it features beautiful floating islands that contain a tiny village and extremely detailed architecture.

In Unigine Heaven 2.5, we see some pretty close performance to the ASUS GTX 560 Ti which can be had for around $200 now for the 384-core version. With these numbers, the HD 7770s only fall about 15% behind. If you've kept track with the two HD 7770s' performance against each other, you have noticed that the numbers are a mixed bag and they perform quite closely.
