So I am gonna start my graduate college by this month end and am planning to replace my 2011 MacBook Pro 13 ( Non-Retina but with 8GB ram ). I have already ordered an iMac 5K with i7 and M295X but can't decide which laptop to get - I won't be doing anything intensive on my laptop, mostly media consumption but I still don't want it to lag after a few months! So I have couple of questions - 1- How fast is it compared to my current model? People are comparing it to 2013 Air models. 2- Can I run MATLAB on it? That's my BIGGEST concern cos I will be using MATLAB extensively - both at home and classes. 3- How big a difference is there between the base level processor ( 1.1 ) and the top end model ( 1.2 )?
