I don't want to sound like a complainer, so I want to start off saying I don't hate the new Mac Pro. I'm okay with the aesthetics and I like the specs. But I am disappointed because it feels like Apple created a new pro that is no longer for me. I'm heart broken because it feels like a "breakup" is going to happen soon where I really don't want to.
I own Mac Pros for a while. G3, G4, G5, 2009 Mac Pro (with 8 cores). My first 8-core Mac Pro cost me $3000+ (I forgot the exact amount I paid for it). and I never regretted it. I upgraded with Sapphire Radeon GPU, and even with the OWC's PCIe SSD. It was heavy as heck! My only complaint was I hated moving it. 2013, I saw the "trashcan" Mac Pro and upgraded to the 8-core model for a little under $5000. I knew then I needed to start saving up for my next Mac Pro when this one inevitably gets obsolete in 5-7 years. It's almost that 6-year mark and I've saved roughly $6k for my next upgrade... but I really needed more cores not more IO. My workflow is to run VMs (windows VM). I'm beginning to feel a CPU pinch in my VM's performance and would have really liked it to give more virtual cores to my VMs.
MacOs Fusion with Windows VM + Unity provided me one of the BEST VM desktops I've experience, and I used Windows as my host, Linux (Redhat, Ubuntu, Elementary-Loki)... With Linux I've been really testing my productivity with various Linux flavors with VMware Workstation Pro (and KVM and VirtuaBox) -- VMWare still provided me the fastest performance even on Linux. But my own evaluation of Linux is still much less ideal than Mac OS.
I was really hoping $4999 - $5999 would be a 16-core SKU, and not an 8-core SKUs... and that AMD Ryzen zen3 CPUs would have help drive down cost where $5000 would get us 16-cores easily. But at $5999+tax and I still can't even get more core-count meant I may need to look elsewhere to spend $5K (though I was saving for $6-7k). I'm not very hopefully even for $7k (after tax) I can get 16-core from Apple's Mac Pro.
With Threadripper at 32-core/64-threads, and Zen3's 12-core/24-thread, it's making me think I'd have to force myself to use Windows10 host (with painful process of locking down custom security and disabling the annoying Windows update), and run my VMs that way off VMware Workstation.
Had $5999 been a 16-core SKU, I would have easily upgraded to this new SKU so that I could stay with the MacOS hostOS. I haven't finalize my decision yet... still conflicted, I need to see if AMD really would release a 16-core Zen3 CPU or not, and/or see what $5000 could get me in terms of threadripper. I really want something in mini-ITX form factor (easy to move around). I do have an old HP BlackBird002 gaming chassis I saved that I can convert to threadripper.
But Windows 10 Pro/home... uck (I like Windows 10 Enterprise a lot though... no forced auto-updates, and it leaves me alone to be productive and never cost me loss of work).
