Since the shader count is 80% of the old grouping, there is some space saved, and on top of that AMD has had a lot of time to optimize area.
This should end up no slower than the old way for simple calculations, the overwhelming majority of the workload, but also be faster for most of the complex operations. The biggest change is in the shaders, they have gone from a 4 simple + 1 complex arrangement to a 4 medium complexity arrangement. Previously, it was assumed that a product codenamed Southern Islands would appear first using Evergreen shaders surrounded by new "Uncore" components, but more recent news suggest that AMD is jumping directly to their next generation shaders on the existing 40 nm TSMC fabrication process. Northern Islands is the next generation of AMD GPU chips that will arrive in 2010 as a successor to Evergreen.

Both SKUs use the full 256-bit memory bus width. There are 1280 stream processors available to the HD 6770 (Barts XT), and 1120 stream processors to the HD 6750 (Barts Pro). Compared to the "Juniper" die that went into making the Radeon HD 5700 series, Barts features twice the memory bandwidth thanks to its 256-bit wide high-speed memory interface, key components such as the SIMD arrays split into two blocks (like on Cypress), and we're now getting to learn that it uses a more efficient 4-D stream processor design. AMD claims that the HD 6700 series will pack "Twice the Horsepower", over previous generation HD 5700 series.

RADEON HD 6700 SERIES UPDATE
The company has admitted that it wants to update the branding of the products from ATI 57xx to AMD 67xx to reflect their standing among the current generation.Here is the slide we've been waiting for, the specs sheet of AMD's next-generation Radeon HD 6700 series GPUs, based on a new, radically redesigned core, codenamed "Barts". It's also worth noting that AMD isn't exactly trying to hide Juniper's identity crisis. The new cards have received support for HDMI 1.4a connectivity and hardware-accelerated Blu-ray 3D video playback. The 6750 is set at about $105 while the 6770 is $120.ĭespite being rebadged versions of their numerical predecessors, AMD has added a few extra features to the 6700 series. This is also reflected by the fact that the prices haven't been increased - at least judging by the current PowerColor and Sapphire 6700 boards available through Newegg. As you can see by the table below, the main specifications between the Radeon HD 5750/5770 and Radeon HD 6750/6770 haven't changed at all. Apparently, that isn't the case as a flurry of AMD's board partners have just unleashed consumer versions.ĪMD says the 6700 cards will replace the 5700 products at the retail level over the coming weeks.
Although we've known since earlier this year that the Radeon HD 67 would be rebranded 57 cards, it was believed that they would remain exclusive to system builders. First appearing in 2009's Radeon HD 5700 products, AMD's Juniper graphics processor has reemerged with a fresh disguise courtesy of the "new" Radeon HD 6700 series.
