AMD's 28nm mobile graphics roadmap leaked

By on
DonanimHaber has published a presentation slide that outlines AMD's mobile GPU roadmap for the next year. The company launched its 40nm Radeon HD 6000M chips (codenamed Seymour, Whistler and Blackcomb) last November, and that lineup will remain in play until later this year and early next year as AMD ramps up production and distribution of its next-gen mobile graphics.

The Radeon HD 7000M will be manufactured on a 28nm process and features four GPUs: Thames, Chelsea, Heathrow and Wimbledon (least to most powerful). Slated for release in November 2011, Thames will have a slightly higher TDP of 15-25W than Seymour (6400M) and it pack twice the performance, which is partially thanks to a 128-bit memory interface (up from 64-bit).

AMD appears to be blurring the lines between its mainstream and performance segments. Chelsea will operate in the 20-30W range and also features a 128-bit bus. Nonetheless, it should bring a 30% speed increase over existing Whistler products (6600M/6700M). It's also due in the last quarter of this year, presumably alongside if not soon after the arrival of Thames-based chips.

AMD is preparing two enthusiast GPUs representing different thermal levels. Heathrow will have a TDP above 35W and will be offered in 128-bit/192-bit variants with 1.5GB/3GB of VRAM. Meanwhile, Wimbledon will represent the series flagship, featuring a 256-bit interface and a 65W TDP. Heathrow should land this year while Wimbledon is coming in the second quarter of 2012.

In other company news, AMD has announced an initiative dubbed "Project Mjölnir" that focuses on "increasing performance and providing improved stability of the AMD Catalyst software."
