As I still contemplate which 2011 MBA I want to keep (the 11" with i5 1.6/4GB/128 GB or the 13" i5 1.7/4GB/128 GB), I'm wondering why I see such a huge difference in benchmark scores for the processors? I mean, it's only a 0.1 GHz differnece, but the Geekbench scores are like 20% higher for the 1.7 for some reason? And for further comparison, the MBP 2.3 i5 is then only 7% faster than the 1.7 (even though it's an additional 0.6 GHz faster processor). Am I just missing or not understanding something? Thanks!
