MBP 13''Core 2 2.4ghz and MBP 15'' i5 2.4ghz processors , what is the different oo? both also 2.4ghz
Core 2 Duo 2.4 Ghz... vs i5 2.4 Ghz..
can say like comparing 1.8L proton engine vs 1.8L turbocharged honda vtec engine. both also 1.8L, but one is much better
also, the i5 2.4Ghz can actually go up to 2.93 Ghz

another difference between the size is the graphics processors. the 13" got 320M which is not that fast but pretty decent. the 15" has intel HD, which is very slow compared to the 320M...but the 15" got another GPU, the 330M, which is around double the speed of the 320M
if you're comparing between those two models, maybe u can share with us what are you going to do with ur notebook. that way we can give u a better recommendation
