Information on upcoming mobile chips from AMD are beginning to filter. Good news, the chips will increase from 40 nm at present, a fine engraving appeared on the Radeon 4000, 28 nm. The first chips will come into production in the third quarter of 2011. Thames, expected in the fourth quarter, will use a 128 bit bus and should provide twice the performance of "Seymour".
As a reminder, Seyamour is the codename of the current Radeon 64xxM, featuring 160 units of computation and a 64-bit bus. Chelsea, scheduled for the same date, replace "Whistler", which is used in chip family 66xxM (480 units of computation). Finally, Wimbledon will be a high-end chip, expected in the second quarter of 2012 and has a 128-bit memory bus.
This chip will replace "Blackcomb," the GPU Radeon 69xxM. There is also a smart Heathrow in the roadmap, but it is not indicated as etched into 28 nm. It could therefore remain at 40 nm to limit costs and the memory bus would be on 128 or 192 bits.
