Old vs new Mac Pro and iMac

I have been thinking about upgrading my MacBook Pro to either an iMac or a Mac Pro. I had been thinking about a Mac Mini but some responses I got on some forums concerning the power in the Mini made me decide that it would not be a good fit for what I needed.

I configured both iMacs and Mac Pros on the Apple website and got prices but, out of curiosity, I decided to check the same configurations at some of the Mac vendors. I specifically looked at both B&HPhotoVideo and Adorama because that is where I buy some of my camera stuff and I have been satisfied with their responsiveness and customer service.

While the Mac Pros were considerably less expensive on the websites I noticed that they were listed as late 2013 models. The specs seems the same as now (3.7GHz i7 chip, 8-16GB RAM, etc) but they were running Mavericks. That made me wonder if there were any hardware changes between late 2013 and late 2015 in the Mac Pro. The same question would apply to the 27" iMac Retina although the vendor versions of those were not quite so old.

Can anyone tell me if I can assume that the hardware in a late 2013 Mac Pro is the same as in the current Mac Pros? And what about a 2014 iMac compared to the current version? I don't mind saving some money but I don't want to do so by buying outdated hardware.

Thank you for any help.
