AMD Mobility Radeon HD 7000 Series Reality by Q4-2011
Shortly after finishing off the top-order of its Radeon HD 6000 series desktop discrete graphics processors (GPUs), AMD is letting out information about its first line of GPUs built on the 28 nanometer fabrication process. The first products carrying the Mobility Radeon HD 7000 series brand identifiers are notebook GPUs in the MXM 3.0 form-factor. AMD is planning an entire lineup top-to-bottom to address almost all mobile computing market segments. At the very low end of course would be its Fusion accelerated processing units with GPUs embedded. On top of that is what follows.
The lineup begins with "Wimbledon", an ultra high-end mGPU. It has a 256-bit wide high-speed GDDR5 memory interface, 2-4 GB of dedicated memory, and 65W TDP. The DirectX 11 GPU will be about 25% faster than "Blackcomb", the Mobility HD 6000 series flagship. This is slated for Q2-2012. Next up is the high-end "Heathrow" mGPU, which has a 192-bit or 128-bit (selectable between variants) GDDR5 memory interface, 1-3 GB of dedicated memory, up to 45W TDP, and 30% higher performance compared to "Chelsea". This is slated for Q4-2011 (this should tell you that Radeon HD 7000 series will be in existence towards the end of 2011).
Going down, there's "Chelsea" itself, with its 128-bit GDDR5 memory interface, 1-2 GB memory, 20-30W TDP, performance 30% higher than "Whistler", production starting in Q4-2011. Lastly, there's "Thames". This mainstream mGPU will have 128-bit GDDR5 with option of GDDR3, 1 GB memory, 15-20W TDP, and 100% higher performance than "Seymour", Radeon HD 6000 series' mainstream mGPU. Production for this starts in Q4-2011, as well.

am I the only one confised, maybe I missed a news report about the Mobility 6000's...
It takes 2 years to plan, design, simulate, test, order samples, take delivery of samples, test more, refine, reorder, etc... for a GPU or CPU architecture change. Look how long we have been waiting on bulldozer.
(basically when ever they actually get bulldozer out the door)
I'm not sure how to do the math but I'm sure that's around/over 200gb/s but also Hynix has made GDDR5 chips that can run at 7GHz effective speed, how many hundreds of gb/s bandwidth is enough? :p
And besided MXM SUCKS!! It can only provide a max of 75W to the interface....They should make revision C asap.
If companies saw the MXM form factor as a way of making profit out of laptops, don't you think it would be more evolved than it is now?
I got a pseudo-MXM card on my toshiba and I'm very upset about not being able to replace it with something better.
Test the waters with low power samples before they go with the higher clocked and power hungry desktop series.... why not
they always stick to 256-bit~
at least use like they produce in 2900XT which has 512-bit bus witdh~
with the incriment of the bus witdh i think ATI can beat nvidia gpu's~
