So, I am looking at getting a pimp Mac set up. (I currently own a fairly beefy "cheese grater" Mac Pro.)

It seems that the new iMac Pro is worlds ahead of the current Mac Pro offerings available. (at least, the price point proves that out).

If you were to get a spec-maxed setup, what would you purchase???
 
The only downside is the graphics card is a consumer grade card in the iMac Pro whereas the one in the Mac Pro is a commercial grade card.

I actually thought that the downside of the Mac Pro was the graphics...compared to the iMac Pro. (gaming performance for the iMac Pro graphics KILLS the Mac Pro) Not sure if that is the end all comparison or not...
 
This is a pretty good review on the new iMac Pro. I think it's worth watching if your in the market.
 
The GPUs in the 2013 Mac Pro are both old, underpowered, and the OS and software are not completely optimised for dual GPU apps. 'Professional' GPUs have things like double precision which are mainly aimed at scientific workloads and offer little to pro-sumer workloads. A single powerful consumer grade GPU was always going to beat that kind of a setup, especially if Apple never upgraded the original ones.

Apple bet that the work load would go the other way, with heavily parallel applications coded to work with dual GPU. That was always a small market within a small market and would have required apps to be rewritten to suit it, the high prices and lack of internal expansion options made potential customers hesitant to buy but Apple then torpedoed it themselves by then refusing to upgrade the Mac Pro while maintaining their customary radio silence - only later admitting they'd made a big error in their design assumptions.

The Vega GPU in the iMac Pro is tuned to fit within the heat profile and isn't replaceable. Professionals would probably prefer to have access to a genuine PCIe 3.0 x16 slot to upgrade their own card and have software support.

It appears that Apple will go a third way by officially allowing folks to fit their own GPU (as long as it's a specific AMD one) into an eGPU box that connects via a PCIe 3.0 4x Thunderbolt connection. You take a slight performance hit 10-15% due to fewer lanes and Thunderbolt overhead and some may balk at the price of adding a better GPU.

What kills the the 2013 Mac Pro is:

1. Only Thunderbolt 2, no official support for eGPU.
2. GPUs are old and have known problems.
3. You might be able to upgrade the (old) RAM but the storage SSD doesn't use a standard connector.

On the flip side, purely on account of being new, the iMac Pro is decent value for money if you needed the 5k screen, the RAM, CPU and the GPU and weren't overly bothered about the relative lack of expansion. If a new Mac Pro came out it could be assessed on a level playing field but we're not there and the massive gap in the Apple lineup for a more affordable headless Mac remains untapped.
 
The only downside is the graphics card is a consumer grade card in the iMac Pro whereas the one in the Mac Pro is a commercial grade card.

The GPU in the 2013 Mac Pro is a (pair of) consumer Radeon 7xxx with a RAM expansion, and a firmware that misrepresents its identity as a FirePro when viewed in macOS.

Hey from my experience it will weigh heavily on what you are planning to 'do' on the mac. I am about to take an iMac pro (base model) back to apple, as my 10 year old Mac pro 3,1 actually handles some stuff better and not far behind in others. I'm really confused what to wait for now, as i expected the iMac Pro to be such a beast all round, but its just not noticeable against a decent running system if you already have one.

the iMac Pro is fast for render and export, and compared to my cheese grater it's about 2x speed (after effects) i think if you're in final cut you'd add zeros to that, but AE doesn't make use of the iMac Pro power. For me the render is time to make tea, go to the loo, go to sleep etc, so its not much difference to me at that point in the job. You could even get two i7 5k iMacs, and just switch machine when render time hits, this could be my next plan, as also i7 will be better for AE i think ...

So in actual normal day to day use, its hardly noticeable the difference, the timeline updates slightly quicker but not much. and in illustrator the iMac is super laggy dragging around a mid sized document, that is totally fluid to drag around on screen on the 3,1. pretty disappointing for a 10 year wait and £5k

I think these 5k screen just use so much GPU power that the equivalent Gb per Pixel means my 970 4Gb card on a 30 inch (2560x1600 screen) is actually more powerful. thats the only reason i can think that things move more swiftly on my old tank. The problem increases if you use display scaling on the iMac Pro as you're just asking it to work even harder to deliver more content to the screen.

I think my issue is that a) i'm not using Final cut where gains would be made, and b) ive upgraded the 3,1 a fair bit over time so it has PCIE boot drive, couple of SSD drives for current work files + a load of HD for storage, 32Gb ram, and a GTX 970. so it all runs well and those upgrades were not super pricey.

The other thing - and i think this is the main thing for me, the screen seems tiny! I currently have a 30 inch apple display (and a 2nd one plugged into the pc next to it). but the 27 inch imac just seems like i'm penned in, and the scaled resolutions don't help much. the half way setting between 'standard' and 'more space' where it says "looks like 2880x1620 (apples description)" is the closest useable setting to me ACD appearance, in terms of what windows you can fit on screen, but its still physically smaller, so going back to the ACD seems like stretching your legs, its so much nicer, even with the 'fuzz' of non retina. I just have to stop looking at the iMac until it goes back and my ACD seems fine again. despite having thought 30inch were too large for the last 10 years, i now see they are a glorious large desk or workspace, and im so glad i plonked the money down for them when they first arrived. These and the cheese grater are the best money i ever spent!

sorry i think i might have gone a bit off topic...
in conclusion, i'd pimp that mac pro until something suitable comes along for you, unless you are doing lots of final cut rendering...
 
iMac Pro is better in every way... If you can get past the fact that you're stuck with the built-in screen for life, and you can't upgrade components.
I personally can't get over those annoyances, so I won't be caught dead with an iMac Pro. But it's still an undeniably powerful machine....
Personally, I'm waiting for the modular Mac Pro for one more year. If it's not announced within a year, I'm just jumping ship altogether.

I know it personal personal preference, but I can live the the 5K Retina Monitor annoyance. ;):D

I like having a 32" monitor minimum, so yeah, for me the 27" is a huge deal breaker. Can't wait for the modular Mac Pro... if it's actually happening....
