So here are the first official
pictures of both the HD 6850 and HD 6870: Radeon HD 6870 Radeon HD 6850
The NDA for performance tests expires on Friday the 22nd. But as a sneak preview, here's something I found over @ Hardforum.com (grain of salt as always):
1920 x 1080
8x AA, 16x AF
Intel Core-i7 920, 6GB DDR3 Ram
1120 meaning 'Radeon HD 6870'
920 meaning 'Radeon HD 6850'
