    My 2011 MBP has 16 GB, and a 500 GB SSD. Can I expect much of performance increase doing Photoshop, Lightroom, and Excel if I upgrade to a current 13 rMBP?

    Thanks!

    5-10% increase in some tasks that are heavily reliant on CPU, depending on your current CPU speed.

    The SSD would be much faster, but once you get to SATA 3, you're really at a point of diminishing returns.

    I'd say it would be significantly more than 5-10% in a number of tasks as the newer CPUs additional instructions in hardware for some tasks. Anything that makes use of OpenCL (in the future) will end up much faster as the integrated GPU which OpenCL can make use ofis much, much faster.

    Battery life is much better, when not being pressed the 2015s don't even turn the fan on, it sits on 0 rpm.

    SSD speed is insane yes, 1400 megabytes per second i have measured...

    Not really no. They're still both a dual core.

    There should very notable increase in GPU, I believe the 2011 13" utilize the HD 3000 which are abysmal at the time of release and Intel has significantly improved their Integrated cards (HD 4000 was when they started to be barely good, 5100 Iris was when they became acceptable, though the extra 8 Eu on the 6100 helps a lot with the retina resolution). Additionally you might see increased performance due to the improved cooling in the 2012 redesign and Broadwell architecture running cooler than the Sandy Bridge architecture so the Turbo Boost speeds will be held longer. The 6100 Iris also supports one 4K display at 60 Hz and has partial support for H.265 if that matters.

    Never mind that one core is 4-5 years newer with significant architecture improvements...


    edit:
    and yeah, on GPU stuff, which more media apps are starting to make better use of (and this trend will continue) it isn't even close.

    As above the CPU benchmarks are 20% or so faster. GPU is several orders of magnitude faster in GPU compute.

    Artificial benchmarks rarely translate into real world performance. You'd be hard pressed to notice any performance difference between both processors in real world usage.

    I do agree wholeheartedly about the GPU though.

    OP:

    You're probably wastin' your money to upgrade from a 2013 to a 2015. The "improvements" will seem marginal, unless you've got $$$ to burn.

    Perhaps when the -new- MBPros come out within the next couple of months (maybe even sooner), there will be enough improvements to warrant a new one.

    Or... just hang in there another year until 2017...

    2011 to a 2015 not 2013 to 2015.

    Yes quite a boost for anything GPU wise (around 2-3 x) about 20% for CPU performance. However your usage will benefit more from PCIe.

    To be honest it will be PCIe ssd's and better bandwidth and ram that helps your use case.

    However wait for skylake (should be in the next month or so for the 13 inch) the GPU boost could be 20-40% over Broadwell
