Macbook Pro i7 - But Not Quad Core?

    I'm deciding between which used MBP to buy, and yesterday, it was brought to my attention that older i7 MBP's may not actually be quad core.

    If you look on the official Apple Specs page (How to identify MacBook Pro models), Only the Early 2011 and newer MBP's have "Quad Core i7" processors, and the rest are just "i7". I also checked a benchmarking site (Mac Benchmarks - Geekbench Browser) which confirms this, and the pre-2011 MBP's with faster clock speed i7s are showing significantly lower benchmarks than the 2011-on MBPs. However, when I google the model of the processor, on sites like NewEgg, it states quad core, so I'm hearing both sides.

    What is actually the case here?

    2009 and earlier MBPs used C2D dual core (no Hyperthreading) CPUs, 2010 MBPs (except the 13" model) used i5 and i7 dual core (with Hyperthreading) CPUs, 2011 and 2012 MBPs (except the 13" model) use quad core i7 (with Hyperthreading) CPUs.

    Old news. Apple skipped nehalem quad cores, which were a bit hotter. i7 doesn't mean quad core. On mobile chips "qm" means quad mobile. It's not like they ever claimed quad chips where they weren't used.

    You are correct:

    2009 and earlier used the mobile C2Ds.
    2010 used the Dual Core mobile i7s.
    2011 and later used the Quad core mobile i7s.

    Every year they became better but the QC models came after 2011.
    Also 13in models does not have QC only dual.
