With the release of the Cayman GPU, the new GPUs don't perform as well against the competition as they did when Cypress was announced. Radeon HD 6970 accelerators are able to compete only with the GeForce GTX 570, but not with the flagship of the "green" - GeForce GTX 580.
It's been a little over a month since Advanced Micro Devices introduced Barts-based Radeon HD 6800 mid-range graphics cards, and the company is now releasing two of its most powerful Cayman-powered single-socket solutions.
AMD has launched a decisive attack on Nvidia's position in the segment of mid-price discrete graphics cards, announcing the delivery of the Radeon HD 6870 and Radeon HD 6850 models.
