    AMD is launching there next gen GPU next month in October. AMD GPU's are 30% smaller than NVIDIA's GPU, thus they require less power.

    Perhaps Apple is now comparing Intel's GPU against the GPU from AMD at this moment? :cool:

    No. They're scrambling to make more 5S's. Everyone from Cupertino got flown over to Foxconn and is working the assembly line.

    Smaller usually doesn't mean less power. You can trade die area for power efficiency. Sometimes tranistor layout that is more efficient or running more excution units at lower speed usually is more power efficient than running fewer units at higher clock speeds.

    Size doesn't mean it needs less power. Just means it is cheaper to produce and can be sold for less.
    In any case the new Hawaii chips are aimed to combat the GK110 Titan chips. Not exactly mobile at around 250W TDP. AMD won't have any mobile GPUs with the new GCN 2.0 architecture ready any time soon.
    That upcoming chip might end up in a Mac Pro but not in a notebook.

    Whatever performance comparison they did for the upcoming MBPs they did months ago.

    No way with an expected release of the next 4 weeks. Maybe for next springs refresh.

    Not sure what exactly you're getting at with your last question as Intel's GPU is integrated into the CPU. Apple can't replace it with something else. Perhaps it was just a typo. :D

    By 30% smaller, I am assuming you mean AMD's 20nm process opposed to NVIDIA's 28nm process. This would suggest that AMD would be able to fit twice as many transistors into the same area as NVIDIA, and therefore should in theory be twice as fast, for the same cost. Or, just as fast for half the cost. Or, just as fast, just as expensive, but using 2/3 of the power. In practice, it won't work like that, but it should still be a fair improvement.

    Either way, there is no reason Apple cannot include a GPU significantly more powerful than even the very expensive Iris Pro, whether it's a NVIDIA 750M/760M, or new Radeon 9770M.

    That said, we'll just have to wait to see if/when/what new mobile GPUs get announced.

    Considering the Mac Pro is using two AMD GPU's I wouldn't discount the possibility.

    My opinion exactly.

    The new chip is also still 28nm. 20nm is coming in 2014 at the earliest. Some sources even claim it will take till late 2014.
    It is just a smaller more tightly packed chip on the same old 28nm. I think the design was initially planned for 20nm and they could use it but 20nm isn't there yet. This whole tranistor shrinking game is slowing down, only Intel sits on enough R&D Budget to keep up a good pace.

    Most people of the Waiting for Haswell MBP Mega Thread considered it unlikely, but AMDs Crystal mobile series are an option. The release date is not a problem. AMDs Hawaii series will be launched in october. And WCCFtech earlier reported, that the correspondig Crystal mobile series would launch sooner than the desktop version. The online seminar for OEMs has been avaible since july. So manufactures already have testing samples.

    Then there's nVidia's executives' intemperate Apple-bashing comments to the tech press over the past couple years, and the company's own foray into tablets.

    Apple might be having a tough time divorcing itself from Samsung as a supplier, but nVidia would be much easier to kick out of bed. And frankly they've been askin' for it.

    I am sure that Apple has had access to both AMD Volcanic Islands and Nvidia Maxwell hardware samples for some time now. On his blog, netkas notices that references to these cards are already present in 10.9 drivers.
