    Will the 480M be nearly as good as the desktop 5870 or far from it

    Quite a ways off. The 480M is a GTX 465 with a severe downclock (around 30%), and the GTX 465 is roughly 10% slower than the desktop HD 5850, which is in turn roughly 15% slower than the desktop HD 5870.

    Like lackofcheese said, it will be a fair ways off, but that's not to say it's any slouch. When it's available, and when we start seeing it in a few more laptops, I'm sure quite a lot of enthusiasts will pick the GTX 480M over the Mobility Radeon 5870 as it will outperform it by a fair bit, from what pre-release benchmarks are showing. Considering the MR 5870 is a downclocked desktop 5770, that's pretty impressive for a notebook GPU.

    i would say GTX480M should be 10% more powerful than 5870M but the 50% greater power cosumption IMO isn't worth it.. can't imagine how much SLI will consume..

    Compared to the 5870M, I'd expect a ~20% advantage in DirectX 10 games, though possibly a lead of as much as 40% in tesselation-heavy DirectX 11 games. However, that second lead stands to be reduced to some extent when AMD starts using its SPs to help with tesselation.

    So far we know it will be better, but there are not any benchmarks yet. So it is anybody guess what will be the real difference.

    He said desktop 5870, not laptop 5870.

    Desktop 5870? I wouldn't have thought it would come close. Better than the mobile 5870 for sure, but not the desktop one.

    EDIT: Looks like I got ninja'd.

    Yep, I misunderstood for the laptop 5870, not the desktop. And it seems I wasn't the only one confused :p

    Still there aren't any benchmarks to compare how different are the cards.

    Read the other threads, it doesn't consume 50% more power. nVidia's TDP figure encompasses everything, while ATI only is the core. And without any real benchmarks to show anything, I'd question everything you've said.

    If he was comparing the official TDP's, he'd have said 100% more power. If we assume that the HD 5870 consumes around 70W all up, the figure would be 43% which isn't far off 50%.
