    100W GPU at P4500 would be an epic fail. 100W is the limit to what they can push out to notebooks. If P4500 will be the greatest they can produce right now with Kepler, they can just quit and surrender to AMD alltogether since AMD have made a P5800 GPU and there is no way people are buying the 680M.

    P4500 at 100W would mean that they will have to wait 6 months or something for a improved architecture to get up to P5800, but until then AMD have moved on to the 8000 series, rendering this new GPU useless.

    P4500 at 75-80W would make more sense because it would not combat 7970M, but have a market on its own plus it would take over for 570M.

    This is not the latest rumor. Its old and if you have been using your eyes the last 2 months you would have seen it before. That score is from a GK106, NOT the GK104 MXM you see from the same BS article from videocardz.
    The latest rumor is that Nvidia is working on a new 680M, not this old stuff you keep dragging up again.

    If you're wrong, which I doubt (I support the 680M release with more than 768CUDA but less than 1344) then Maxwell would save nVIDIA. That is according to their performance per watt graph.

    But it doesn`t make any sense. Nvidias Kepler in the desktop area is doing just fine. Why should they have trouble making the same good performance with notebooks?

    They are not stupid. They plan everything up ahead. If they come out with a 100W P4500, I just don`t see what that plan is. Catering for stupid fanboys who will buy Nvidia whatever happens? :p

    Cloud. How would you explain that GTX660M is 75W and is as weak as it is? So 75W GTX660M scores P2700 and 100W GTX680M will score P7000? Wheres the sense in that?

    And GTX680M will not be P4500 according to those leaks, but minimum P4900 and likely above P5000 with new drivers. :)

    660M and 680M likely have such high TDPs because of Nvidia's GPU boost feature.

    I still don`t believe for a single minute that the 660M is 75W like I have been saying for the last month. It is somewhere around 50W. But anyways even if it really were, you can`t compare 660M with 680M because 660M is GK107, while 680M will be GK104. Its two totally different cards. More cores but lower clocked, different turbo clocks, different memory speed, different memory bandwidth etc.

    P4900 score is also total bull. That score is from the GK106 680M overclocked. It was from the same leak where we saw the P4500 score :)

    Please stop using P#### scores, they are not the indicator for GPU. A significant difference in CPU will always yield larger changes in P score and lower changes in GPU score. At least for vantage and 11.

    Anyways, the kepler architecture scaling is a bit wonky so far, it seems to have it's current best balance at GTX670, but power consumption and performance does not scale linearly.

    I think we will see the GTX660ti, or whatever is the 1152 cuda cores, as the GTX680m. Or at least it seems the most likely since it will still be more powerful than HD7970m while not being too much hardware downclocked.

    3dM11 P scores are totally comparable. difference in CPU score doesnt affect much the P score. At least as long as the processors are from i7-2 to i7-3 mobile range, its only maximum 50points difference between the lowest and highest.
    ---

    Anyway. If this turkish reseller put GTX680M in their list then we are likey to see the true specs and scores rather soon :p
    ---

    What comes to power consumtion of GTX660M, then i can do test as soon as i get my W150ERQ and compare it to HD7970.
    GT650M GDDR5 is identical to GTX660M. Only the clocks speeds are different. This can be fixed.

    Because my math estimates the 680M (undervolted and underclocked 670) with 1344 CUDA cores @ ~123.9Watts.

    I think the 680M would have to run around 700Mhz @ .8v with 1344SP to meet the 1344SP expectation..

    He's talking about 7xxx series in general. The 7870 seems to scale pretty well, except for a few games.

    But that's FPS only, there might still be microstuttering.

    I want to break in to Nvidias headquarters and steal that damn 680M. Man I`m sick of this speculation.

    Where do you guys reckon they keep the GPU? California or some underground cave guarded by heavy military? Chopper flying around the entrance, lazers on the wall to detect movement with automatic machine guns that shoot on any movement. If there is some chinese dude who reads this who either owns one or knows somebody who do, I am willing to pay big bucks for you to ship whatever engineering crap you have :p

    i just want two and that they hit 45k+ in vantage perf setting and be able to run BF 3 at 120fps stabel on maxed out settings not ultra preset oh yea stock

    this is what i would want .
    dont care if its unrealistic ;D

    4 different scenarios guys but only 2 that fits the memory configuration of this card. Which one will it be... :rolleyes:

    #1 If the 680M have 768 CUDA cores, it is based on the 130W GK106 GTX 660 and have a 192 bit bus. That can`t be true since the turkish site is quoting 4GB. That doesn`t fit. It must have either 1.5GB or 3.0GB for a 192 bit bus.

    #2 If the 680M have 768 CUDA cores, it may be based on the 195W GK104 GTX 680 (1536 cores) but sliced in half, and have a 256 bit bus which fits the 4GB memory.

    #3 If the 680M have 1344 CUDA cores, it is based on 150W GK104 GTX 670 and have a 256 bit bus. That fits the 4GB memory.

    #4 If the 680M have 1152 CUDA cores, it is based on the 150W GK104 GTX 660 TI and have 192 bit bus which also doesn`t fit the 4GB memory.

    I don't think the 4gb thing really means much, could easily be a typo or just inaccurate information. Clevo resellers were advertising the w110er as coming with a 1gb gddr5 650m and that turned out to be wrong.

    I think, given the power restrictions, the most likely scenarios are 1 and 4.

    Or maybe it'll just be a rebranded 7970m. :eek:

    GTX 660 = 7870 according to some sites btw. So worst case scenario should be downclocked 7870.
    VGA ZOL

    If 660 TI goes, so should 670 R3d since they share the same TDP and probably the same power consumption too (?). Question is what way will give the best performance out of the two.

    GTX 660 looks to be the easiest route, since its only 130W, but that will give a pretty "MEH"-performance over the 7970M. Oh god, please don`t pick this one and let this be Fermi vs VLIW all over again. :(

    ORRRRRRRRR

    nVIDIA release 2 versions. One is 2GB and the other is 4GB with 2 different memory interfaces ;).

    Followed by the *1344* 685M.


    BTW, the card is in Texas or California.

    But 2GB and 4GB still only work on 256bit. Its gotta be 3GB and 4GB or 1.5GB and 4GB

    That 1344 may be our 685M yes but that leave #2 is our only option for GTX 680M. Well it could be that that turkish reseller got the memory amount wrong like R3d says

    113 pages of speculation with next to zero actual information. This thread is a testament to pointlessness and wasted time. Is it so you can say "I told you so" when it's actually released? How many hours have you invested so far for that chance?

    The only thing I'm sure of, is that it isn't a direct translation of any desktop GPU, and it won't be 192-bit.

    Are the shaders in clusters of 24? If yes, it would just mean that they disabled one more. Far from improbable.
    I only see 38 pages and why have you now invested in such an utterly pointless thread? Had some extra valuable time to spare, so you threw it to the peasants?

    I would hope, but it may be a little less. My computer currently runs Skyrim better than CoP, and this card only put Skyrim to ~70. Honestly though, anything over minimum 40 is fine. I can hardly tell the difference myself.

    Ahh thank you, I am looking forward to this. S.T.A.L.K.E.R. is one of my favorite series, and probably one of the more demanding titles I'd be playing. Crysis and Battlefield 3 were never really my thing.

    So you are telling us that its completely new GPU? I can bet against you on that it isnt.

    Here´s GK104:

    I dont think they are able to shut down less than single SMX at the time.
    Not physically and econimically reasonable i think. Perhaps not even physically possible.

    680m to have 4 gigs? If that's true AMD will follow and create a 7970m successor with 4 gigs. I think alienware provides the 7970m crossfire. 580m sli from the m18x gets 100 fps maxed out on bf3. :eek:

    i would love to see the 7970m in CF on a x7200 with 990x
    with max Over volt and max oc what it would do
    since in a x7200 power and cooling for the cards wouldent be a prob 2x 300w psu's
