    Specs:
    13 inch Macbook Pro Retina, 2.7ghz, 128gb SSD
    iMac i3: number of cores?
    How many cores does the i3 have? (the one in the base model of the iMac)??

    I'm asking because when I open activity monito, right click on its application icon and choose CPU usage as the dock icon it has 4 bars (representing 4 cores)…I thought the i3 only had 2 cores…

    Specs:
    2013 MBA 13" - OS X 10.12.latest
    i3 has 2 cores each capable of running 2 threads.

    I'm not an expert, but maybe that's where the 4 bars are coming from.

    A computer lets you make more mistakes faster than any invention in human history - with the possible exceptions of handguns and tequila.
    The bitterness of poor quality remains long after the sweetness of low price is forgotten.

    Specs:
    27" i7 iMac, 24" iMac, 13" Macbook Air, iPhone 6S, iPod Nano 7th GeniPad 3
    The i3 is the successor to the Core2Duo and thus has two cores.

    I have the 27" i7 iMac and when I ask for the CPU Usage monitor, I get 8 bars which makes since I have 4 cores and 4 more with hyper-threading..

    So the 4 bars doesn't make sense on the i3..even on the i5 it should only show 4 bars since that one is a quad-core which lacks hyper-threading..

    Regards

    All the iX series of processors support hyper threading, not just the i7's.

    So a dual core i3/i5 processor has the ability to hyper thread into 4 threads. Your 4 bars is just showing the 4 threads possible because of hyper threading.
