Hi guys,
I think this may be a dumb question, so please excuse my lack of knowledge.
(Originally I was going to post this in the laptop section but since it's mainly about CPU's, I thought this is a more fitting place.)
Is quad-core necessarily better (in terms of performance) than a dual-core in a laptop?
To my understanding, most apps do not yet utilize anything more than 2 cores, so why buy a 4 core machine sporting an i7 processor, as opposed to a daul-core i5?
Another confusion I had is the low clock speed of quad-core i-series processors. Yes, they can overclock (or run in turbo mode rather) to a much higher clock, but wouldn't the initial lower clock gives a lower overall system performance? (compared an i7 processor at 1.7 Ghz as opposed to an i5 processor at 2.5 Ghz)
The last confusion I had is about ultrabooks. If the reason to have an i7 processor in a laptop is because it offers 4 cores (instead of 2 cores) and its relatively larger cache, why settle for an ultrabook which currently only sports a dual-core i7 processor? How is it that Apple is able to squeeze a regular quad-core i7 processor in an ultrabook that PC can't, or won't?
Thanks,
