Why is it that apple owners think that any thing made by apple is magically better than any thing else made by other venders?
A Xeon is a workstation/server process but it is still standard off the shelf component. So are all the parts that a mac of any type is made of. There is not nothing special in any mac book or mac pro.
In fact looking at the specs for the mac pro cylinder, these parts are mostly from 2013. Not only is there nothing special here, these are all "old" parts. The high end mac pro is still supporting a PCI 2.0 bus.
If you want to pretend that macs are magically better than PC"s because they have a magic apple on them, then fine. But from the specs and hardware point of view they are nothing more than high end PC's. Over priced PC's.
