Difference b/t mobile processors?

post #1 of 3
Thread Starter 
Hey guys, looking to buy a laptop w/ sandy bridge CPU in the next 2-3 months.

One question I have is what is the difference between all the dual core Core i3/i5/i7 processors besides the frequency?

I'm specifically talking about all the 2C/4T processors that have 35w TDP. Like the i3 2310M, the i5 2520M, and the i7 2620M. Does the i7 perform better clock for clock compared to the i5 and the i3? Or is the only difference between these the default/turbo clock?

The amount of Cache is one of the main differentiating factors between those processors. The i7 Dual Core variations have 4 MB of cache vs. 3MB found in the i5/i3 variations. Although technically the 2 core i7 is faster clock per clock.....not by much. If you're going to fork out the money for an i7 SB mobile laptop, spend a little bit more and make it a quad core version. Otherwise, I'd go with the i5.

Thanks, that's what I thought. Online vendors charge a lot more for the i7, so I'll probably just go w/ the i5.
