I've been using the iMac Pro for a week now. It really is faster than my old 2015 iMac for everything, even though it's basically using the same processor just with four extra cores. They're both using SSDs, so it's not like it's Fusion Drive v SSD. Sure, the old one had 16gig RAM and the new one has 64, but the old one never really struggled for memory.
The difference in general architecture seems to make more difference than the list of components.
The Vega56 is also excellent. I'm getting 75FPS in F1 2023 at 4k resolution in Bootcamp.
I'd be surprised if the vanilla 2020 iMac is any faster than the 2017 iMac Pro in general use personally, even though I know the benchmarks show the 2020 faster on occasion.
