    A leaked slide over at the anandtech forums shows up to 35% longer battery time on video playback with a Skylake m-core over a Broadwell m-core.

    This is of course an ideal situation that might not be directly representative for "normal" use, but definitely interesting news.

    Very nice. Looking forward to the next-gen of this MB.

    Im looking forward to the bump of the integrated graphics bump! HDMI 2.0 support what what!

    Truthfully I don't really understand the slide. Does it hint at any CPU improvements?

    But it sounds like it won't be this year for sure.

    It has improvements all over the chip, including GPU/CPU and so on. Skylake is a tock, meaning a new SoC arch.

    Boardwell is just a 14nm process shrink of the same Haswell arch, that's why there aren't a lot of differences.

    Skylake is where a lot of big changes are coming, including DDR4 support which will have some power efficiency gains, especially LPDDR4 for laptops.

    But I wouldn't expect major gains in pure math throughput, expect maybe at least 2-5% gain for CPU and 10-20% in GPU. The biggest improvement is going to be the energy efficiency, they're already expecting 30%.

    Yes, all true, but DDR4 support isn't coming to the Y-series chips with Skylake, according to the Intel Roadmaps. Also, Y-series is definitely not going to be released until 2016. Lastly, it appears they are comparing to a Broadwell 5Y10 processor in the infographic according to its footnotes...hardly representative of the processors used in the current MB.

    It seems like the next rev. won't be out until 2016. Maybe a year after the MBP 13" refresh and Macbook introduction? I've ordered a 1.2/512 and will be happy with that for the next year. And then I'll most likely sell it and upgrade to rev. 2. :)

    I just bought a 2015 macbook pro and Im very pleased with it. But I will have to most undoubtably sell it and buy the new revision with skylake for a few reasons...

    1. 4k compatibility (not mst, real 4k)

    2. the gpu for gaming

    3. most likely they will up the specs on the current display (hopefully 4k)

    4. energy efficiency is nice, but less so than 1-3

    I wouldn't hold my breath. Why tax the machine with an even higher resolution if the eye won't even notice.

    I really doubt apple will put 4k on the next version of rMB for soooooooo many reasons. Just a few are power consumption, lack of such a screen on MBP.

    Also, it's Intel that puts the integrated GPU on the chip, not Apple. I doubt that Skylake M is going to have such a huge jump in GPU that it's going to suddenly be a gaming machine. Again, better GPU takes more energy and Apple and Intel have to balance energy usage with performance on core M chips.

    GPU with 5W TDP for gaming? Man, for real? I know you man not necessarily mean running Crysis on full details in 4k, but if you want to wait for rMB for gaming, that may take a while :D

    Next generation can do better when watching movies only if it will feature full hardware decode support for popular movie formats. For other task, you probably wont notice any change.

    From marketing perspective, I think that putting only USB-C, slower than rMBP SSD and lack of 4k output is there just to make us, customers switch for Skylake revision in the future :)

    Have we seen any roadmaps for mobile? Seems to have been a few for the desktop market...
