GPU Performance
The Core i7 also has a slight increase in max GPU turbo frequency (1.2GHz vs. 1.15GHz), however that only amounts to a maximum performance increase of 4%. For the most part there's no real impact on gaming performance, although Portal 2 showed a 17% increase - likely due to the faster turbo modes and larger cache.

I see the performance gain is not much with 13 inches i7 upgrade but can the 4 MB cache shows itself in other ways that may not be directly measured by typical performance tests? For example will it help with faster switching applications if a large number of applications are running at the same time. As an example lets say we are running XCode with many files open, Interface Builder, iPhone Simulator, Firefox, Safari, MS Word, iTunes plus some other apps. How about if I don't turn off my mac for many many days (quite typical) and there are just more and more applications which are active on it. Could it be more responsive with i7's 4MB cache rather than i5's 3 MB?ningmeng - Friday, March 23, 2012 - link
