Forgive me for my ignorance, but I had some questions about Quad-Core VS Dual-Core and Geekbench Scores. So I currently own a 2012 13" Macbook Pro and am looking to add a desktop as well, but one that is 'faster' than my laptop. If I understand correctly, having double the amount of cores should theoretically make a computer twice as fast as one with a similar chip/processor? Yet when I compare the iMac I want to my Macbook the Geekbench scores are faster, but not anywhere near twice as fast. Am I missing something? Does having a previous generation Intel i5 chip make that much of a difference even with double the cores? (please ignore the 3rd Mac listed in the screenshot below, Everymac lets you compare 3 different Macs and it's just the default.) I want to have a desktop that's much faster than my Macbook Pro, does that mean I at least have to get one with the same year/processor for the quad-core to show that much difference than the dual-core?
