FUD Zilla heard AMD's entry-level Radeon HD 6000 series "Caicos" and "Turks" GPUs will most likely arrive in late January or early February 2011:
This is the current plan and the codenames should we well known by know Turks and Caicos. Turks should replace Redwood, while Caicos replaces Cedar.
These will be the new chips, not rebrands, but AMD didn’t really talk much about this to its investors. From the roadmap one might conclude that Turks comes in early Q1 2011, while Caicos comes a bit later.
