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.

ok lets say high memory speed from ATI and more wide memory bandwidth from nvidia it give same frequency, but question who give more heat and who will more effective ????
Why does my 7500 only have a pci slot?It doesnt fit in my PCIE slot?
the 2900XT is a good example of this gone wrong, that card was a complete mess late in its life
and most of the time the GTX260 was faster than the HD4870 in actual gaming
A mobilty card with 256-bit GDDR5 will assumedly be a fantastic performer, hec a 5770 isnt bottlenecked by 128-bit GDDR5 and the juniper based mobility chips are already a heap of power on the go.
