AMD has finally made up its mind about the launch of Barts PRO and XT. These new cores will sport Radeon HD 6870 and 6850 brands, but it looks like that they will end up marginally slower than the original 5870 and 5850.
Don’t worry though, Cayman is still supposed to launch this year most likely with the HD 6890 if not 6970 / 6950 brands. We still don’t know these brands but this is something that would not surprise.
The two cards launching on Friday are the Radeon HD 6870, with 1GB GDDR5 as well as HDMI,DVI-I, DVI-D and Dual mini DisplayPort outputs, and the Radeon HD 6850, also with 1GB GDDR5, DVI-I and DVI-D, HDMI and DisplayPort.
The cards will start shipping to shops by the end of this week or early next week. You should be able to buy them in e-tail / retail shortly after launch.
