    According to Notebookcheck.com, here the spec:

    GTX 560M GTX 660M

    Pixel Share 192 384
    Core Speed 775 835
    Shader Speed 1550 835
    Memory Speed 1250 2000
    Memory Bus* 192 128

    It seems like with alittle over clock on GTX 560m, you can pass GTX 660M easly, plus, because of the memory bus, GTX 560M will work better on 720P/900P/1080P, no? or I am wrong?

    Finished with my comparison!

    The 1GB GDDR5 128bit GT 650M is pretty much a 1.5GB GDDR5 192bit GTX 560M. If not better. So yeah GTX 660M will be even better than that ;)

    Food for thought:

    Memory Bandwith:
    GTX 570M/670M 192-bit: 72.0 GB/s (GDDR5)
    GTX 660M 128-bit: 64GB/s (GDDR5)
    GTX 650M 128-bit: Up to 64.0 (GDDR5 have that)
    GTX 560M 192-bit: 60GB/s (GDDR5)

    1.5GB GDDR5 192bit GTX 560M in 1080p with Heaven Benchmark 2.5

    GT 650M is always better by virtue of it being new tech. I am sure some would disagree with me though.

    DDR3 version is almost like 460M. No and No.

    Try looking at what I posted for you and ask again.

    Notebookcheck doesn`t give you any valuable information, but they guess that the GT 650M DDR3 version lies somewhere between GTX 460M and GTX 560M. They even temporarily put the GT 650M name over GTX 560M. :)

    And the numbers you are comparing is not very helpful. First of all a Kepler core is NOT equal to a Fermi core. Second, the 128bit bus doesn`t mean a thing. Which you will understand if you just read what I wrote to you (It have faster memory which makes the bandwidth bigger than the 560M) :)

    GT650M with GDDR5 will outpace the GTX560M.

    I also think something like that. Where do you think GTX 660M will be?
    Anandtech suggests a scenario where GT 650M could have 336 cores at 850MHz or 384 cores at 735MHz while GTX 660M have 384 cores at 835MHz.

    I think the 660m will perform almost as well as the 570m but I don't think it will outperform it. It will definitely consume less power though.

    GT650M type A - 835mhz, 384 cores, 128bit DDR3
    GT650M type B- 735mhz, 384 cores, 128bit GDDR5
    GTX660M - 835mhz, 384 cores, 128bit GDDR5

    You will just have to know the machine to know if you are getting A or B.

    GT cards will not support SLI.

    GT650M GDDR5 could possibly be volt modded as the core voltage will likely be a little lower, but I doubt it will use a different PCB on an MXM module compared to the GTX660M.

    Now double the clocks and bandwidth to get the GTX660M. Due to the design of the core to run that fast I would expect linear scaling.
