I just bought a new iMac with the i3 processor. On my MacBook Pro with a C2D, iStat showed two graphs for my processor cores, which I expected on a dual-core CPU. But now on iStat, it shows four graphs. I am pretty sure the i3 isn't quad-core. Does anybody know why iStat would do this? I know I read that the i3 does hyper-threading, but I don't think that would simulate four cores. Thanks for any answers.
