I am pretty sure the 2020 iMac will be more than enough.
I gave you a real world way to find out. If your tasks don't take that long, then you should be ok.
Yes, I depend on this computer to make money but at the same time having a task finished a couple of minutes earlier doesn't really make a practical difference.
I don't spend that kind of money for
"a couple of minutes". But yes, if that's the real difference.
Then I probably wasn't talking to you.
Your argument is not relevant here. The OP described his use and we advised accordingly.
But you
don't know and constantly post as if you do — and
that's my point. Advice is worthless without knowing the tasks at hand.
He posted some apps that, if the files the files are large enough and require complex rendering, the differences between the two machines can be hours (if days, he needs a Mac Pro 7.1). He never mentioned mentioned anything that would let me know exactly — likewise, he didn't offer you guys any information to justify your claims, either.
Without context — and there still is none here — your pronouncements that something is or is not correct are worthless.
But how much time do you take by working of the files before launching the rendering?
Minutes, hours, days, weeks — depends on the layers, project and its length. I have access to a 28 Core 7.1 with a pair of Vega Pro II Duo + Afterburner and a $150k Maya Box for the really heavy lifting — but not here. The more I get done here, the better.
but most of the time the real, practical usage of the computer is : waiting for input. Waiting for OUR input, actions, etc.
iMac Pro is outdated and with the current specs it makes not much sense unless you go for CPU rendering and can't afford the Mac Pro.
Neither of you seem to know enough about this subject to be having this conversation with me. The 2020, iMP and 7.1 are using 3 versions of recent Intel CPUs—there's no magic here. It's a very safe bet that, as long as Apple is supporting Intel architecture, all 3 will still run the latest OS.
In three years, it's likely that all will be replaced by ARM but even then, Apple will support the last Intel OS for three years after its release — California, EU and other laws apply. The argument that the current iMP will be obsolete sooner than a 2020 using the same architecture is just silly.
Again, lost in the fog is that I have A/B'd the two machines on typical work files just last week. Then I sold my 14 Core and bought an 18 Core.
