The guys over at it.com.cn have finally cleared up the controversy surrounding AMD's naming scheme that has been rumoured for quite some time, and it looks like that the new HD 6800 series performance GPU series will indeed be based on Barts GPU.
According to several leaked slides, the Radeon HD 6870 is going to be based on the Barts XT GPU, while Barts Pro is reserved for the HD 6850. Of course, AMD's higher performance Cayman and dual GPU Antilles based cards should come at a later date. The pictured card is described as the HD 6870 reference design and despite its similarities with the Radeon HD 5800 series, there are quite a few differences as well. The card appears to be as long as an HD 5850 reference card, although it's something that has still to be confirmed.
The rear panel is where all major changes are to be seen, at least on the design side. The exhaust part looks to be a bit wider, and the output selection is a whole lot different. The pixellized card features two DVI, one HDMI and two mini DisplayPort outputs. Although the precise details regarding the Eyefinity aren't revealed, there are some rumours that the card could have a support for up to five displays.
The leaked documents also list a "Eyespeed" feature that hasn't been detailed, but we are sure that more info will show up pretty soon.
