    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…

    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.

    27" i7 iMac, 24" iMac, 13" Macbook Air, iPhone 5 & 5S, iPod Nano 7th Gen, iPad 2 16GB WiFi, iPad 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.
