    Is there place you see the speed in graphics and CPU comparing the two? Got the maxed old iMac about a month ago. Like see comparsion of old CPU and new skylake performance wise.

    Thanks,

    Chris

    I did hear the force touch magic track will work with older iMacs w/El Cap installed.

    Other area of interest is the differences in the video cards and screens themselves.

    For a rough idea of how CPU performance compares check out Anandtech's Skylake desktop CPU review.
    http://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/18

    In short, the CPU performance difference between a 4790K 4Ghz i7 in a 2014 Retina iMac and the 6700K 4Ghz CPU in a 2015 Retina iMac is generally insignificant (between 2-5% on average with a few outliers).

    For GPU performance it's somewhat harder to speculate, as even though the m395x isn't that much faster than the m295x on paper, Apple and AMD may have managed to get the thermals under control this time around which could result in a nice, albeit not earth shattering performance increase.

    So then have how much better is the monitor and how much is the force touch track pad used in OS. If real handy I buy the new track pad.

    I have read that the new Force touch trackpad is only compatible with the new iMacs with bluetooth 4.0. Not sure if its true but I read it on a tech website. Can anyone confirm this?

    On paper the M295X and M395X are identical. Allegedly.

    AMDs data is just a reference point. The M295X used in the previous riMac was clocked at 850 MHz, and M395X will probably be clocked even higher. Apple can and will play with the MHz, don't forget that.

    It runs 3 to 7 degrees cooler. That's great. Perhaps less throttling this year

    EDIT: referring to skylake versus haswell
