Nope, from what I've read they are both dual core with hyper-threading. In fact, I can't find any sources that show any real difference between them other than clock speed. Maybe someone with more CPU expertise could enlighten me - do the model numbers in Intel's mobile processors now simply denote clock speed differences? http://www.engadget.com/2010/01/07/intel-core-presser-32nm-core-i3-core-i5-and-core-i7-cpus/ http://www.engadget.com/2010/01/07/intel-core-presser-32nm-c...

Yeah, it's basically just clock speed in the mobile CPUs, and of course the higher end i7s have 4 cores (and no on-chip graphics). Some desktop versions also omit hyper-threading and/or turbo boost.

Corei5 does NOT support HyperThreading unlike Corei7

  That's incorrect. All mobile Core i5 processors have HyperThreading. http://ark.intel.com/ProductCollection.aspx?familyID=43483 http://ark.intel.com/ProductCollection.aspx?familyID=43483 In fact, there are only two Core i* processors that don't have HyperThreading support, and they're both variants of the same quad-core Core i5 desktop processor (Core i5 750 and Core i5 750S): http://ark.intel.com/ProductCollection.aspx?familyID=42912 http://ark.intel.com/ProductCollection.aspx?familyID=42912

There isn't much difference between the cpus apple is offering. The i7 has 4mb of cache instead of 3mb, higher base clock speed, and higher turbo clock speed. Here is Intel's infromation on the three chips: http://ark.intel.com/Compare.aspx?ids=47341,43544,43560 http://ark.intel.com/Compare.aspx?ids=47341,43544,43560 For some other cases, there are bigger differences between the i5 and i7, but not for these chips.
