Sapphire HD 7970 Dual X Review

» Discuss this article (7)


Unigine Heaven Benchmark 3.0 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.



  • 4x AA
  • 16x AF
  • Shaders = High
  • Tesselation = Normal
  • Measurement = FPS











Higher = Better


In the Unigine testing, the Sapphire HD 7970 OC again is neck and neck with the XFX 7970. It shows some strength in overclocking when competing with the GTX 680 and crazy overclocked Sapphire 7950 OC.
