I'm trying to do some research for a friend and I'm a bit baffled at what I am finding. Is it possible that a mid-2009 Unibody MBP has worse performance than a late-2006 MBP? Specifically, I'm looking at the video cards. The 2.33ghz C2D MBP has a dedicated ATi X1600 Card with 256mb of vram, while the 2.53ghz C2D Unibody MBP has an integrated Nvidia 9400M with 256mb of shared vram. Looking at Notebookcheck's benchmark site (http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html) it would seem that the ATi X1600 ranks higher at position #145 than the Nvidia 9400M at position # 161. Am I missing something here? How can Apple put a worst video card in a machine that is three years newer? I would appreciate if anyone could elaborate this. Thanks.
