    Question is, why wasn't there a full GM204 mobile from the beginning? It may very well be, for example, that obtaining a high quantity of fully enabled low leakage parts was at first impossible, but has now become possible. In which case even at a 100W TDP there may be a large increase in performance.
    Or it may be that fully enabled GM204 mobile was simply held back for purposes of having a refresh later, in which case, as you said, there will be no or low performance increases at 100W.

    Why would Nvidia need to out a full-die GM 204 before this point? The GTX 980M (and GTX 970M for that matter) already sit above the competitions highest performing mobile AIC, the R9 M295X.
    Seems counter-intuitive to lead with your best performer when you aren't obliged to do so - especially from amortization and refresh strategy points of view.

    Yup. I should have been more clear. There is no doubt in my mind that not releasing the full GM204 mobile was the right move for Nvidia. The question is whether they actually had any other option, due to yields of low-leakage parts.

    Quadro M5000 is a full GM204 solution with 6.6GT/s memory and 1050MHz of boost clocks (base clocks not mentioned), with a 150W TDP.

    There's your GTX 990M.


    Doesn't make any more sense than the boost clocks (which AFAIK are actual clocks and make a big difference to the actual performance).
    The base clocks for the 980M are already 1038MHz. 30% above that is 1350MHz for base (or what you call actual) clocks. It's still ridiculous.

    My point was that the GTX 980M theoretically has 70% shading, 75% texturing and 70% memory performance of the desktop GTX 980.
    The GTX 980M actually has 58-75% of the performance of the desktop GTX 980.
    There is a possibility that the 12% performance gap against the reference card arises from the GTX 980M throttling more. The performance gap against binned cards is even larger.
    No matter how you call the clocks that matter, increasing the power limit is a way of increasing actual, not theoretical, performance.

    All of that is correct, but it doesn't invalidate the fact that your post claiming up to 30% higher clocks with more enabled units on top is a completely unrealistic goal for a GM204 on 150-180W.

    It was ludicrous then and it's ludicrous now. That's my only point.

    They could have binned enough GPUs by now to do it.

    33% more enabled units. With 1.5-2 times the previous TDP + more time to bin low-leakage GPUs.
    There is a reason for the up to. If the game is already power-limited, it will be the one that gets 10-15% higher clocks. If it isn't power limited, it might get more, if Nvidia unlocks additional voltage bins.

    In the same ballpark as your 1300Mhz Fury X :)

    *cant edit yet*
    Seems theres been some discussion about Async on some previous pages, still theres some weird things going on when Devs are asked by Nvidia to disable DX12 features for performance.

    It's the GTX990M, a GM204.
    It claims 1190MHz core clock, but those values are probably only attainable with the watercooling block attached.

    So, this is essentially "980Ti" for laptops, since the mobile SKU nomenclature is usually bumped up, compared to the spec's.

    Isn't the normal 980m exactly the same chip but with shaders deactivated and at lower clocks?

    I don't understand how these laptop chips can be so small and the desktop cards so unbelievably massive. Especially considering some 980m versions have 8GB of RAM.

    Isn't the memory bus butchered tho; I only count eight chips. So, not quite full desktop class, unless I'm mistaken of course. :)

    8 chips at 32bit is 256bit, so yes, full desktop. GTX 980/970 has 8 chips too.

    They've probably been binning these chips for a long time. The margins must be crazy...
