    Okay so I understand that desktop processors are faster then notebook processors, My question is will the 2011 iMac's quad core processors be comparably faster then the 2011 Macbook Pros quad cores?.

    For example the desktop version of the Intel Core Quad i5 processor would be faster then the notebook version of the Quad Core i7?

    There is alot of speculation that the new Quad i7 will not make it into the 2011 iMac's, so will the new 2011 quad core i5 desktop processors be faster even though they are not i7 processors?

    Sorry, I am usually a technical person, I understand the basics, but when it comes down to these newer processors it gets tricky!

    Thanks,
    Frankysavvy

    Now who said that. And yes the next iMacs will no doubt be faster than the macbookpros. The macbookpros made the jump to sandybrdge while iMacs have not.

    i5 and i7 are just model names, they do not refer to the performance when comparing mobile and desktop CPUs. The slowest desktop i5 is as fast as the fastest mobile i7 (when excluding HT).

    That's not necessarily true when comparing different generations of processors. For example, the i7-860 (2.8GHz desktop Lynnfield/Nehalem) is definitely slower than the i7-2820QM (2.3GHz mobile Sandy Bridge).

    But it's definitely true overall that desktop Sandy Bridge will be faster than mobile Sandy Bridge and that the i7-2600 (the most-likely high-end processor for the next iMac refresh) will kick the snot out of the i7-2820QM in the high-end MacBook Pro.

    When comparing different micro-architectures, only benchmarks matter. All other numbers are pointless (including core count, frequency, cache, model number, price...). I was assuming we talk about the same generation of CPUs.

    I figured that's what you meant; I was just trying to clarify for the OP.

    Most likely not i7 because there is only one i7 model (i7-2600). You must leave something for the high-end too.
