Sapphire HD6670 Ultimate, HD6750 & HD6770 Review

» Discuss this article (13)


Unigine Heaven Benchmark 2.5 is a DirectX 11 GPU benchmark based on the Unigine engine. This was the first DX 11 benchmark out 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.



  • AA = Off
  • 1xAF
  • Shaders = Medium
  • Tesselation = Moderate
  • Measurement = FPS












Higher = Better


Sapphire's HD6770 was able to sit right around the middle once again in the Unigine 2.5 benchmark, the HD6750 was trailing close to it with the two HD6670s at the bottom of the chart.
