AMD Radeon HD 6670 and 6570 Mainstream GPUs


Test Setup & Unigine Heaven v2.1

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

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.

As of this writing, Radeon HD 5770 and NVIDIA GeForce GTS 450 cards can be found for prices ranging from about $79 to $119 (after rebates), so we've included performance numbers from those two cards as points of reference throughout this piece.

The numbers show the new Radeon HD 6570 and HD 6670 trailing the previous-gen cards by a fair margin in the Unigine Heaven benchmark.
