Can someone help me understand this? According to this compilation of Geekbench benchmarks http://www.primatelabs.com/blog/2012/12/mac-benchmarks-december-2012/ the top end 2012 Mac Mini is basically within 10% of the speed of the top 27" iMac despite the fact that the Mini is using a processor that is about 2/3" the speed and a mobile processor to boot. Can someone comment on real world performance of these two machines? What I'm really after is a fast machine for photo processing, but if a Mini with 1 TB fusion drive is really so close in performance for that application to an iMac, I'm hard pressed to see why I should go with the iMac. Thanks!
