honestly don’t underestimate, the power of the guys from hollywood at apple... I don’t think the 2019 is going anywhere, the price is high, they don’t loose money, they will keep producing it... music industry is covered for the next 10 years with the actual macpro.
but music is not the only business... anyone doing live video capture, or broadcast video, let alone motion picture industry need a lot of pcie slot...
for people like me the 2019 is a tool, and already paid for itself .
Please keep in mind that for some people, it is nothing more than a tool, and that we are used to buy other tools that cost way way more...
look at the price of a true 10bit reference monitor for grading... 30k for a 32 inch monitor... look at a zeiss master prime serie... look at a promise vtrack... I sometime think that there are a lot of people hating/loving apple for emotional reasons ... but actually a lot of those who give advice/their opinion /criticise... actually don’t own a 2019 macpro, nor are doing a business in witch such a machine is needed... so they miss the whole point of this machine and find it an overpriced useless piece of equipment...
now concerning what apple will do regarding MPX, once again, for the market of this machine, if you need gpu power you buy twin pro2 duo...
they don’t really care about making a mpx module with 6000 serie until amd tell them « we don’t have any chip anymore, lets go with this chip » .
what you have to understand is that in large companies who actually buy those machines, no one « upgrade » anything... if you need an upgrade, you tell the IT guy what you want, and it takes 6 month to get validated... or if you need it right now it is bought the next day...
Only a very marginal share of customers for those machine are geek like me who buy a 8 core base model and upgrade it by their own with parts bought from ebay.... and truely apple dont care about customers like me... I am ok with that...
so realistically, as I said, to me as soon as rx5700xt is discontinued, you will see a rx6000 serie on new machine, and then on apple store.
very probably a pro 6500x for entry level, a pro 6700/800 to replace the 5700, and for pro 2 duo, as soon as amd discontinue the instinct Mi60 and replace it , you will see another 7000$ top end gpu offer as a mpx...
they only need 3 gpu :
one low end for music industry that only take one slot.
one middle class - sub 1500$ after apple tax - single man band- graphic/motion designer video editor...
one top notch « money is not an issue, give me all youve got » gpu for motion picture/3d/high end motion designer /grader/editors... this will probably not be a 6900, because with apple tax it wont sale, people will buy pc ones.
so basically we need to wait that they retire the pro 5700x and the very high end will be a 7k option not for us... but we will be able to find used pro 2 duo for the price of a pc 6900 ....
