Test Setup & Unigine Heaven v2.5

How We Configured Our Test Systems: We tested the graphics cards in this article on a Gigabyte GA-EX58-UD5 motherboard powered by a Core i7 980X six-core processor and 6GB of OCZ DDR3-1333 RAM. The first thing we did when configuring the test system was enter the system BIOS and set all values to their "optimized" or "high performance" default settings. Then we manually configured the memory timings (DDR3-1333, CAS 7) and disabled any integrated peripherals that wouldn't be put to use. The hard drive was then formatted and Windows 7 Ultimate x64 was installed. When the installation was complete we fully updated the OS and installed the latest DirectX redist, along with the necessary drivers, games, and benchmark applications.

Unigine Heaven v2.5 Benchmark
Pseudo-DirectX 11 Gaming


Unigine Heaven

Unigine's Heaven Benchmark v2.5 is built around the Unigine game engine. Unigine is a cross-platform, real-time 3D engine, with support for DirectX 9, DirectX 10, DirectX 11 and OpenGL. The Heaven benchmark--when run in DX11 mode--also makes comprehensive use of tessellation technology and advanced SSAO (screen-space ambient occlusion) It also features volumetric cumulonimbus clouds generated by a physically accurate algorithm and a dynamic sky with light scattering.

The HIS Radoen HD 6990 performs at essentially the exact same level as the reference Radeon HD 6990 card in this benchmark, but neither can keep pace with the GeForce GTX 590. NVIDIA currently has a distinct advantage in terms of geometry and tessellation, and it shows in a benchmark like this that uses a ton of tessellation at the options we used for testing.
