    Just wondering, with a high end 27-inch late 2013 iMac and a high end late 2015 iMac, is there much performance difference besides the 5K display? Is the SSD faster? Thanks.

    Technically...yes, like mentioned. However it will depend on your workload to determine if there is a real world gains or not.

    For example, there might be a 25% (just for example) gain when it comes to a game and a 0% difference when it comes to checking your email.

    I have both 2013 and 2015 top-spec iMac 27s, the only difference is my 2013 is Fusion Drive and the 2015 is SSD. There is not a huge performance difference but in some specific workloads the 2015 iMac 27 is significantly faster.

    On benchmarks the SSD is super fast but on many real-world workflows, SSD isn't much faster than Fusion Drive. However I slightly prefer the SSD, and there are less common cases where you notice the difference. See attached spreadsheet with tests, mostly focusing on CPU, GPU and FCPX.
