We received some details about the name of the chip that ATI codenamed Cypress which we have called RV870. The internal generation codename is Evergreen and this name represents the entire DirectX 11 generation of ATI cards.

The top card is named Radeon HD 5870 but the company plans two versions, one with 2GB memory and one with 1GB.

The Radeon HD 5870 1GB should sell for $399 at launch, while Radeon HD 5870 2GB should sell for $449. At the same time, the slower Radeon HD 5850 with 1GB memory will sell for $299. The launch date for all three cards is September 23rd in Europe whereas in the US we are talking about the 22nd.
