Following the details regarding AMD's 28nm ultra high-end Wimbledon GPU, posted details on the full lineup of AMD's 28nm Mobility Radeon HD 7000 series. As noted, the Wimbledon ultra high-end GPU will be followed by Heathrow, Chelsea and Thames, all scheduled for Q4 2011 production.

The Heathrow GPU will have two versions, with either 128 or 192-bit memory interface. The high-end Heathrow GPU will have between 1.5GB and 3GB of GDDR5 memory, a TDP between 35 and 45W and should be 1.3 times faster than the performance class Chelsea GPU. The Chelsea features a 128-bit memory interface, 1GB of GDDR5 memory or 2GB of GDDR3 memory, 20 to 30W TDP and should be 1.3 times faster than Whistler GPU (a 40nm GPU that should show up in early 2011).

Last but not the least is the mainstream 28nm GPU, codename Thames. This one has a 128-bit memory interface, 1GB of either GDDR5 or GDDR3 memory, 15 to 20W TDP and should be 2 times faster than the Seymour 40nm GPU also scheduled for early 2011.

As noted, all of the mentioned GPUs are 28nm and all are scheduled for production in Q4 2011, except the Wimbledon ultra high-end GPU. Of course, bear in mind that these are early specifications and some things might change till the end of 2011.
