While we might have previously called these upcoming parts R870 or Evergreen, the two working designs are actually being given names of Evergreen trees. The high end part will be dubbed “Cyprus” and the mid-range GPU will be called “Juniper”. Obviously AMD is putting trees in preferential order now.
So, what are those code names? They are Cypress and Juniper. Cypress is the big chip, and Juniper is the mid-range part. ATI strongly hinted at the conference that the wafer was a Cypress, but I don’t recall if a chip code name was explicitly stated. It it was Cypress, die size estimates in the 180mm^2 range should make Nvidia very nervous. If the wafer was a Juniper, Nvidia should be far more nervous.
In the end, if you see people calling any specific part Evergreen, they don’t have a clue and are making things up. This was a very clever move on ATI’s part, it likely will gain them at least 3 levels of cunning when they level up.
