AMD Turks-Architecture based video cards will be powering the Radeon HD 6670 and Radeon HD 6570, replacing the Radeon HD 5670 and Radeon HD 5570 respectively, both based on the older Redwood-Architecture.

Compared to the Radeon 5500-5600 series cards that the 6570 and 6670 replace, the performance increase is app. 10% for the 6670, while the Radeon HD6570 is very close to the Radeon HD5670.

Compared To:

Over 30 graphics cards ranging from the AMD Radeon HD 4870 to the HD 6970 and NVIDIA GeForce GT 220 to the GTX 580.

Benchmarks Tested:

Test Setup:

• Mainboard : Asus Rampage II Extreme
• Operating System : Win 7 Ultimate x64
• Processor : Intel Core i7-920
