    Did Intel put you up to this?

    I might just get one of those GE60 or 70s. They look like pretty sleek machines and the 650M seems to be the GK107 sweet spot. We'll see what else appears next week. :)

    The more media versions of the gt series, weaker graphics, one hdd slot and no flashy lights. however they are cheaper and lighter.

    This 28nm process is really interesting... small increase in voltage = exponential increase in power... :)

    AMEN! I can't believe this. Wasn't Kepler supposed to offer twice the performance per Watt?! 660m is rated at the same wattage as 560m! So much for using the 660m for sub 15" notebooks
    What gives Nvidia? Your whole angle for Kepler was a vastly improved TDP and thus feasibility of higher performing chips in smaller notebooks, as opposed to greatly improved performance.
    I guess the lesson is don't believe Nvidia's marketing if they're going back to Hyperbole and lies.

    if this is so, wouldn't it make more sense to just add more shaders to 660M instead of more Mhz? By the way, I have a notebook with 3.0a mxm slot, will i be able to upgrade to 650M at least?

    Folks, stop ignoring GPU boost which bumps up the TDP.

    If 660m's TDP is 75W then I'm disappointed, since the 650m GDDR5 is only 45W and it's not much weaker.

    I wonder if there is a GT 650m with MXM 3.0 lol.

    They don't have the desktop cores out to harvest a mobile Kepler part with more than 384 shaders at the moment. Eventually I expect defective and cut down 680Ms (GK106) to find a place between the 650M and 680M. Maybe not until the 7XXM series though.

    I feel you pain Cloudfire. 75 watt for the 660M! I waited months for 660M and didn't get Sandy Bridge + 670M when Clevo shipped out because I was expecting lower TDP. I saw 75 watt listing a couple of days ago for the 660M on Eurocom's website too, but I thought they made a mistake. Eurocom will sell 660M for the same price as the 670 too. So you're paying premium for newer technology, but lower performance. If this is true then I might have to settle with 670M + Ivy Bridge.

    650M is probably the only worth while card for this whole 6XXM series. It's just too bad that it's not MXM otherwise I am happily sacrifice some performance for lower TDP.

    That would be true but the problem is that 670m still has more shading power. At least when overclocked.

    They should have made the 660m a stronger performer, not the same chip as 640/650m. And also 192bit bus.

    Why do you assume 650M won't be released in MXM format? I guess that some manufacturers will solder the chip to the mainboard and other will use the MXM interface. Also there is AMD 7870M which is better than 660M as for perf/W goes. It may even be as fast as 670M while consuming only 50 W or so.

    Does anyone know if the 660M is under NDA? It would be weird if it still is since it is available to order with Asus G75. I want one with a Clevo, but it seems like nobody is offering? Logic Blue Online is offering, but I don't live in Australia.

    If its available right now, especially if Asus is selling theirs, its not under any NDA. That said its impossible to find any benchmarks of the 660M except from the thread in the Asus forum. Strange :)

    I figure. I guess the parts aren't available yet at least may be the MXM version anyway, since somebody said that Asus' 660M is soldered on.

    I asked a few resellers but it seems like nobody has an ETA. I don't want to settle for the 670M since 660M run much cooler with slightly less performance.

    On that same Asus thread I think they are saying dell might've been wrong about 75W TDP, it might actually be 45W, thoughts?

    the 660m would be much more competative if it was 45w

    Guys , I’m confuse with the GT 640M, GT 650M and GTX 660M core clocks.

    On Nvidia sites, the graphics clock
    GT 640M: 625 MHz
    GT 650M: 850 MHz (GDDR3)/735 MHz (GDDR5)
    GTX 660M: 835 MHz

    As we can see NVIDIA Control Panel screenshots by other reviews too, its show the GT 640M, GT 650M and GTX 660M all have same 405 MHz Graphics Clock and 810 MHZ Processor Clock.

    Also I understand that Kepler has no more hot clock. I’m missing something?

    Nope the 660m is 75 watts. If you go to the Alienware site and check out the graphics cards (help me choose) it lists the 660m as 75 watts. I'd give a link but internet is slow as heck for me at the moment.

    Nope, no hot clocks.

    Just GPU-Z does not support it yet.

    Some manufacturers are using 3.0b MXM form factor for 660M , which means its power consumption excedes the maximum power consumption allowed by 3.0a (55W). Otherwise there would be no reason to use bigger pcb and heatsinks. For example :

    http://web.eurocom.com/EC/ec_components(225)

    Plus, this one also lists the 660M as 75 W

    Hot clocks traditionally meant the shader clock in fermi type cards (amd before) so i would not use it.
