We haven’t talked about it beyond a passing comment, but AMD still has some Radeon 6000 series cards that are OEM-only. We are of course referring to the Radeon HD 6770 and Radeon HD 6750, AMD’s Juniper-powered 5770 & 5750 rebadges for OEMs. While we’ve only recently seen the rest of the Northern Islands lineup launch in the retail space, in the OEM space the last-generation Juniper GPU has been filling out AMD’s lineup between Turks (6500/6600) and Barts (6800) based video cards.

The rationale for OEM space is rather straightforward: OEMs want/need something new to sell. More RAM, a Sandy Bridge CPU, a SSD – their 2011 computers need to look better than their 2010 computers, as they certainly don’t want to be seen as selling last year’s model for anything less than a steep discount. It was perhaps a foolish hope that these shenanigans would remain in the OEM market, as so far AMD has continued to keep the 5770 and 5750 even after the rest of Northern Islands has launched. But here we are, out with the old and in with the old: the 5770 and 5750 are getting rebadged in retail. Say hello to the Radeon HD 6770 and Radeon HD 6750.
