    Is it true that the GTX 260m is actually an slightly overclocked 9800m GTX and doesnt use the new technology like the desktop variant of it?

    Ive seen a laptop coming out soon with an HD4870, will it be much faster then an GTX260m?

    Which laptop? i know the alienware has true 4870s (i think) but the gddr3 models (asus) are about the same speed as gtx 260m.

    The GTX 260M is an OCed and 55nm 9800M GTX. It does not use the desktop technology. The HD 4870 in all laptops (except the Alienware which uses GDDR5) are just OCed HD 4850 and perform around the same as the GTX 260M. Haven't seen benchmarks of the Alienware system but it should be much better than the GTX 260M.

    Hmm, not really overclocked 4850s, they are based off the r770 though and there core extentions (r770xt blah blah) and the ati counterparts are based off there desktop ones, but Nvidia really tend to shrink dies and blow the clocks/shader units up some more and there set.

    The difference btw HD 4870 GDDR3 and HD 4850 GDDR3 are the clock speeds and nothing more, so that's why I consider it an OCed version.

    I'd say from the specs, significantly. Haven't seen benchmarks but it would be highly dependent on resolution, I'd speculate anywhere from 0-100% better (low resolution already at like 100+ FPS vs. high resolution you can finally get a playable 40 FPS on some games). GDDR5 effectively doubles the bandwidth, ie. 256-bit GDDR5 ~= 512-bit GDDR3, which is huge.
