Ok, I have what is perhaps a really dumb question. I have a 2011 iMac with a 4-core 2.7ghz i5 processor. The latest 13 inch macbook pro has a 2.7ghz i5 2-core processor. Despite the fact one has twice the cores as the other, their geekbench scores are almost identical. Obviously the newer iteration of the i5 is more efficient, etc. and... I know that a lot more than processor speed has to do with real world performance, but ... just isolating the processor, is there any reason to think one or the other has some kind of advantage over the other, given the fact that one has twice as many cores as they other ... despite the fact that their geekbench scores are identical? My guess, of course is that there is zero difference in how fast these systems will handle processor related tasks, but I thought it was worth asking the question.
