AMD's ATI Radeon HD 5800 line will have five models by the time it's complete, a detailed leak of data shows. The 5870 and 5850 known to be launching first are now believed by Xbit to be just upper mid-range parts that would replace the 4870 and 4850 sold today. Falling under the codename Juniper, they would use the same processor as higher-end chips but would be eclipsed by two higher-end models, Cypress and Hemlock.
