Although Advanced Micro Devices' graphics business unit yet has to release its Mobility Radeon HD 6000-series graphics processing units (GPUs) for notebooks, the first details about the post-next-generation mobile graphics adapters - which will be sold under AMD Mobility Radeon HD 7000 brand - has been published by a web-site.


The Mobility Radeon HD 7000 family of  graphics processors is projected be made using 28nm process technology, but at this point it is unknown which of the chips will be made at Globalfoundries and which will be made at Taiwan Semiconductor Manufacturing Company. It is also unclear which new features will be supported by the new line of mobile GPUs compared to the predecessors, but it can be suggested that they will use VLIW4 architecture stream cores like the Radeon HD 6900 "Cayman" does.

Some of the ATI Mobility Radeon graphics processors will enter production in Q4 2011, but some will only be ready in Q2 2012. The information seems to be in line with AMD's typical approach to start manufacturing of mobile GPUs about one quarter after desktop graphics chips with similar architecture. Potentially, this means that AMD will only be able to release some of its 28nm desktop GPUs only in Q1 2012.

Donanimhaber web-site claims that the Mobility Radeon HD 7000 family will consist of at least four graphics cores named after different places in London, England. It is noteworthy that the family, provided that the information is correct and full, will not include a low-end GPU with 64-bit memory bus. The absence of such chip is logical, given high performance of graphics processors inside AMD's accelerated processing units (APUs) that will power notebooks for performance-minded customers.

The positioning and suggested performance and TDPs look as follows:
