Mid-Range AMD Graphics Card Round-Up (HIS 7770 GHz / HIS 7850 / Sapphire 7850)

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 use the following settings: 1920×1080 resolution. Anti Aliasing: off. Anisotrophy: 4, Tessellation: Normal. Shaders: High. Stereo 3D: Disabled. API: Direct X 11.

Unigine's Heaven benchmark shows more of the same; Sapphire's 1GB 7850 is slightly faster than HIS' 2GB version, albeit by just 1.3%.

The performance deficit of HIS' overclocked 7770 GHz Edition increases to 9.7%, in comparison to the Radeon HD 6870.
