Is it true i5 and i7 is only 30% increase in speed over core 2 dual?

Is it true i5 and i7 is only 30% increase in speed over core 2 dual?

Some one was saying to me i5 and i7 is only 30% increase in speed over core 2 dual?

Is like that with most i5 and i7 ? Or is only some i5 and i7 is going be 2 or 3 times fater than core 2 dual and is it going be very costly?

Do you believe everything you hear without doing any of your own research?

I, for one, do! It is so much easier than thinking or searching.

That is still a secretive matter, and the following site I link to should be kept a secret too: Mac Benchmarks by Geekbench

PS: There are dual-core i5 and i7 CPUs, there are quad-core i5 and i7 CPUs and some of those even support HyperThreading, but then again, you did not specify what CPU you actually mean and
