That 12 core, 2012 Mac Pro was what, $3800 when it went on sale? In 2019 money, according to some inflation calculators, that's under $4300 in 2019 U.S. money. I think Apple got boned by Intel's inability to compete with AMD and we are stuck with old Xeons. Workhorses, but expensive workhorses that don't acknowledge AMD's products.
This Mac pro is stupid expensive at the low end, and the base GPU in that model is a bad value. I imagine at the high end it's very competitive if you edit super high def video. Now that Ryzen 3 exists, and soon a new version of thread ripper, it will fill that mid range nicely and I feel that many Mac users will make the switch to save money while more than doubling the GPU performance vs spending over $5000 for the anemic performance of the base nMP.
The best news to me is that Redshift announced support for the Mac. Cool beans. I may be able to ride out my iMac a while longer.
I would have killed for Nvidia support, though. Just drivers and eGPU support, and I would go on my merry way, oblivious to super high end workflows.
If you spend $1000 on an Apple monitor stand, though, you will be cursed by lovecraftian old gods.
