Here it is, the AMD Radeon HD 6870, all dressed up to go to work. There has been quite some speculation surrounding the naming scheme AMD is going to adopt with the HD 6000 series, but fresh information suggestively lays some of that to rest. Firstly, Radeon HD 6800 series is built around the "Barts" GPU, not "Cayman". Barts is a new performance GPU, though isn't the highest-end single GPU from AMD (which is reserved for Cayman). Barts "XT" is Radeon HD 6870, and Barts "Pro" is HD 6850. Pictured below is the HD 6870. At a purely subjective glance, the HD 6870 reference design card seems to be as long as the HD 5850 reference.

The new Radeon logo has been Photoshopped on to the fan, so the products in market will definitely do away with the older ATI logo. The rear panel resembles that of the Radeon HD 5800 series, except that the exhaust grille seems slightly wider, there are two DVI-I connectors, one standard HDMI, and two mini DisplayPort connectors for a change. The connector output sharing scheme isn't known right now, it could be 3 or 4 head Eyefinity, or all-out 5 head Eyefinity, a yet to be detailed "Eyespeed" feature is mentioned. We will definitely know more about this card in the weeks to come.
