XFX HD6970 3-way CFx & HD6950 CFx review

Unigine provides an interesting way to test hardware. It can be easily adapted to various projects due to its elaborated software design and flexible toolset. A lot of their customers claim that they have never seen such extremely-effective code, which is so easy to understand.

Heaven Benchmark is a DirectX 11 GPU benchmark based on advanced Unigine engine from Unigine Corp. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. Interactive mode provides emerging experience of exploring the intricate world of steampunk.

Efficient and well-architected framework makes Unigine highly scalable:

• Multiple API (DirectX 9 / DirectX 10 / DirectX 11 / OpenGL) render
• Cross-platform: MS Windows (XP, Vista, Windows 7) / Linux
• Full support of 32bit and 64bit systems
• Multicore CPU support
• Little / big endian support (ready for game consoles)
• Powerful C++ API
• Comprehensive performance profiling system
• Flexible XML-based data structures

We test at 1080p so that all video cards can be compared throughout our reviews. Obviously driver updates might enhance performance slightly over time, but as a rule, its a useful way for us to present the findings.

The nVidia GTX580 is the fastest single card in this tessellation heavy benchmark with the single HD6970 in second place, trailing by under 7 frames per second. Crossfire scaling is very strong for the new cards, with the XFX HD6970 in 3 way Cfx delivering a staggering 133.5 frames per second average.

We have included a video of the XFX HD6970 in 3 way Crossfire X rendering the Unigine Benchmark at 1080p. Keep your eye on the FRAPS counter top left.
