    Core i7 Dual Core? I'm pretty sure its a quad core since it has 2 physical and 2 virtual cores..
    But great find I think people come here for coupons a lot

    Cores are different than threads. This one has 2 core, 2 thread on each core. So 4 virtual cores, but only 2 physical. Threads share bandwidth with each other, but cores do not.

    True i7's have 4 physical cores, 2 threads on each core, resulting in 8 virtual cores.

    Regardless my point was that its not a Dual Core as described, it has 4 threads

    It is a dual core as described. Thats what we call dual core computers, dual cores. It has 2 cores. Threads are irrelevant, their impact on performance is nothing next to threads, hence why they arent listed as quad cores.

    A dual core cpu with hyperthreading like that i7 is far less superior than a quad core cpu, even if it only has single threads.

    Think of it this way. When we say a cpu runs at 2.0 ghz and has 2 cores, each core runs at 2ghz. If it has 2 threads on each core, 2 threads "share" the 2 ghz. So if one is processing stuff at 1ghz, the other cannot use more than 1 ghz.

    Dual core refers to # of cores thats it.
