Wow. I used to think folks on Mac forums understood technology. Guess I'm mistaken. Some of you do, but holy cow, the rest of you?
Do you know what a workstation is? Do you know the difference between Xeon and Core CPUs? Do you even know what ECC RAM is?
Apple has built a kick-ass workstation here, at an incredible price (it's about damn time). This is NOT an iMac Pro sans display. It's in a completely different category. This Mac finally competes with the likes of HP and Dell workstations, and bests them in many ways (i.e. gobs of Thunderbolt ports, 10Gb ethernet, "Afterburner" accelerator card option, MPX module options, etc.).
Run on over to hp.com, and custom configure yourself an HP Z4 (single socket Xeon CPU box) with identical specs to Apple's entry level config (or as close an equivalent as possible) and then ask yourself if you have any clue how much workstations cost!
I did that very thing... Matched up each component to exact or near exact items in new Mac Pro. The result? HP Z4 = aprox $7200.00.
Time to educate yourselves.
