Hey guys, I love my 2012 15" Macbook Pro unibody, and whilst I'm waiting for the rumoured redesign at WWDC before I make any purchasing decisions, the weight of the 15", low-res screen and general size is becoming a bit more of a nuisance for commuting etc. and I was looking to move to a 13" model with my next purchase. However, how does the performance compare between the two models? 4 cores vs 2 seems to be giving my older laptop the edge in total Geekbench scores, how accurate is this in terms of real-life performance? a noticeable impact? How does the graphic performance compare? the latest modern-iGPUs on the 13 inch Pros versus my GT650M dGPU unit and HD Graphics 4000 iGPU. I've upgraded my hard drive to SSD so will Apple's latest flash storage for the MBPs offer a noticeably faster experience than I'm currently experiencing? Cheers guys, just trying to gauge whether it's worth the upgrade cost on a performance level - or whether I'm inherently heading for a downgrade in performance by going for the smaller Pro.
