    Hi all

    So got my new 2015 fully maxed out 15" rMBP. Now its lovely and fast but rather larger than my old 13"

    I really wanted the dGPU just incase and spending more than £2k I could get the UK VAT back. So saying me £400 in tax which worked out the same price as the 13" so it seems liked a good idea

    But i'm struggling to get used to the size. The 13" is such a nice size

    The main reason for the laptop is to pair it to my new 24" 4K monitor at 60hz. But was worried the 13" iGPU would lag

    When the 15" is plugged into the 4K monitor the dGPU is used.

    I see the 13" uses a different iGPU to the new 2015" The IRIS pro rather than the IRIS 6100

    So what is quicker the 2015 13" iGPU or the 2015 15" IGPU ? Which seems to be the same as my old mid-2014 13" iGPU

    That old mid-2014 wouldn't do 4K at 60, only 30

    I'm just wondering if the 13" would do smooth 4K at 60hz

    From my limited understanding the iGPU in the 15" is actually better than the iGPU in the 13" even thought he 13" has broadwell.
    The 15" gets the pro version, the 13" does not.

    Not a very technical answer i know but from my research the 15" is simply better. imagine if they released the 13" with a better iGPU than the 15" @@ although stranger things have happened...

    Many people on here seem to be running a 4K with a 13 incher no troubles at all.
