Is an Intel i3 processor for a laptop necessarily better than an Intel Core 2 Duo processor with a higher clock speed? Could the best i3 processor be better than some i5 ones?

No CPU is "better" than another unless you specify what you want it to be good at. You will find every possible benchmark from Intel on their website. – slhck Jun 26 '11 at 9:39
@slhck is right. What do you want from it: efficiency, sheer raw computing power, extra features (eg AES-NI), multithreadedness, price? – Lukasa Jun 26 '11 at 10:02
In terms of sheer computing power, how do these brands overlap? – Michael Parks Jun 26 '11 at 10:47
