    I was looking at the new lenovo Y580. It is supposed to have a GT 660m with 2GB of VRAM. I wanted to know how the 660m will compare to the older 500m series?

    Also right now in my laptop i have a AMD 6750m. How will it compare to that?

    What about the 560m with 1.5GB of VRAM?

    Thanks.

    I do believe the 660m, provided it has GDDR5 (is there even going to be a gimped version?), will be sitting between the performance of the 560m and the 570m of the older cards. It should definitely be a solid upgrade over your current 6750.

    Yeah, while the card has been announced, I don't believe there are any laptops with the card available yet so no benchmarks yet.

    slightly slower than a 570m, significant upgrade from a 560m

    amd 6750m doesn't really compare, these cards are in a separate league.

    The 660m will likely be about 15-20% slower than a current BIOS-flashed 570m (if we take nvidia's word for relative comparison using the 670m as a guidepost)

    The current flashed 570m's are more than double the performance of a 6750m. (as mentioned, completely different league)

    No card can be both of the things you have laid out.

    Wrong. According to Dell it's a 75 watt card.

    835mhz core clock, 384 shaders, 128bit GDDR5 @ 1250mhz (5000mhz effective)

    Certainly it's going to be ahead of the 560M.

    Core counts aren't possible across radically different designs. From what I've seen the 660's better than the 560, but not radically so. I mean it's a good chip though.

    TDP != power consumption. Case in point: The GTX 680 has a 195w tdp. The GTX 465 has a 200w tdp. But the GTX 465 consumes 35w less under load.

    You're assuming that TDP is the maximum amount of heat that the GPU will give out. It's not. It's an arbitrary number set by the manufacturer, not an actual measurement of anything.
