AMD Radeon HD 6970 & 6950 Debut: Enter Cayman

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 v2.1 Benchmark
Pseudo-DirectX 11 Gaming


Unigine Heaven

The Unigine Heaven Benchmark v2.0 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), and it also features volumetric cumulonimbus clouds generated by a physically accurate algorithm and a dynamic sky with light scattering.

The new Radeon HD 6970 and 6950 are a huge step up over the Radeon HD 5870 in terms of performance according to the Unigine benchmark; the 6970 even manages to outpace the dual-GPU Radeon HD 5970 here. NVIDIA's GeForce GTX 500 series cards have an advantage, however, at the extreme settings we used to test. Geometry processing was a big focus for NVIDIA with Fermi and it shows in this test.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
