PowerColor Radeon HD 7870 Myst Edition Crossfire Testing:
Unigine Heaven Benchmark 4.0 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.
- 8x AA
- Tesselation = Extreme
- Measurement = FPS
At stock speeds the GTX 660Ti combo is the higher performing combo. When overclocked it evens the playing field. The narrower memory bus on the NVIDIA cards contribute to the lower scores once you reach 5760x1080.
