    I ordered my macbook pro with an i7 processor thinking that this was a quadcore processor, as stated on the intel website: http://www.intel.com/products/processor/corei7/specifications.htm

    This processor is a quadcore, but with hyperthreading it acts like an octalcore.

    However, when I looked in system profiler, I noticed it naming my processor i7, but only detecting 2 cores. When I looked on the apple website, it appeared that apple sees the i5 and i7 as quite the same, both dual cored who could act as quadcores with multi threading. When I called the apple store where I bought my macbook pro, they confirmed this.

    When I use iStat pro and click on activity monitor -> cpu I clearly see 4 cores, all 4 in use luckily.

    I was wondering if this is apple hyperthreading 2 out of 4 cores, or that really all 4 cores are in use...

    I noticed that 2 out of 4 displayed cores are rarely used, both by system and user. This means that these are 'hyper threaded' cores, or that activity is not nicely balanced over all cores...
