The AMD Radeon HD 7800 series is the third and final entry in the Southern Island series. AMD is pitching it as a replacement for the exceptionally popular AMD ATI Radeon 5800 series, the first DX11 card in the world and the one 28% of STEAM gamers still use. The AMD Radeon HD 7800 series uses the codename Pitcairn for its consumer design and, like the Cypress boards, there are two variants available at launch: Radeon HD 7870 a.k.a Pitcairn XT, and Radeon HD 7850 a.k.a. Pitcairn Pro. This is a preview launch, a paper launch, with actual card availability coming March 19th. AMD tell us this has nothing to do with yields or board supply issues, but to give most exposure to the product in a very busy month - Game Developers Conference and CEBIT are March events, and AMD wants the 7800 in the mix with all the other announcements. Make of that what you will ...

AMD Radeon HD 7850 Specifications:
The pricing of the 7800 series puts the cards in the performance enthusiast sweet spot - traditionally defined at $200-300USD but, capitalizing on the success of 5800 series, stretching toward the $400USD mark. The cards are priced at $349 for the 7870 and $249 for the 7850, lining them up against the GTX 570 and 560 Ti respectively. Expect custom models and reseller markups to push the prices up by about $20 or more.
As you can see the Radeon HD 7870 is an AT 1GHz edition, like the HD 7770. Notably, the HD 7850 only requires a single 6-pin power input. Pitcairn looks to be the spiritual successor to RV770, with high performance/watt with a low absolute power use, given the segment.
