The Sapphire Radeon HD 6850 uses the Barts GPU at 775Mhz and has 1GB GDDR5 memory running at 4000Mhz. The Sapphire Radeon HD 6850 has a 256Bit Memory Interface, 960 Shader Processors and DirectX 11. The Sapphire Radeon HD 6850 faces the Sapphire Radeon HD 5850 Xtreme which has DX11 and 1440 Shader Processors. Software used for testing was 3dmark 2006, 3dmark Vantage, 3dmark 11, Dirt 3, Call of Duty Black Ops, Crysis Warhead and Hawk 2. It's going to be an interesting fight between the Sapphire Radeon HD 6850 and Sapphire Radeon HD 5850 Xtreme which has 34% more Shader Processors for that extra performance impact. The Sapphire Radeon HD 6850 also has a small advantage of a 7% Higher Core Clock Speed which should give it a small performance boost.
