Hello Freida
AMD's Arcturus GPU 'Radeon Instinct' which will feature the CDNA architecture and aim the server market has been spotted, featuring 120 CUs.

It has been rumoured that AMD are going 'Gaming' vs 'Compute' (think iMac vs iMac Pro...)
The Radeon Vega and Vega VII were perhaps 'good' at gaming and 'excellent' at compute. (From what I'd seen of the Nvidia mainstream cards, 'Excellent' at gaming and 'good' at compute.)
It's been muted by the rumours that AMD Radeon are going this route for this 'next generation' of cards. So 'Big Navi' is the 'gaming' card optimised for that. And Arcturis is the 'compute' card specialising in that arena. Radeon has done well in compute so it makes sense they'll keep specialising in that. This has implications (possibly for the iMac Pro...) and even more likely for the Mac Pro.
So it really depends on what kind of creative work you are doing and wish to do. I think the iMac Pro was, in some ways, a 'brave' machine by Apple (though it could be accused of being the path of least resistance to mask their 6 year Mac Pro debacle of incompetence...) But it's a sound machine. And any upgrade (compared to the Mac Pro) would be enticing to those that want 'that bit more' than the iMac can offer. My only argument with the iMac Pro is that it is 3 years out of date and really, it's starting price should be more like £3k. (That's what's it's worth now, in my view. Tops. 8 cores. Pretty standard. GPUS now midrange at best. And the sound system being 'better' is ironic as they downgraded the iMac 27 incher 'tear drop' speakers from those in the 24 inch iMac...and the base wasn't as good in my view, either...)
The key to the iMac's (Or iMac Pro's) value is to lose the monitor (£1k value?) and see what you have left for the price being charged. Clearly the current models are old rope for today's money.
Back to your question.
If you want to game. I'm sure any RDNA1 card will deliver whilst STILL offering good compute performance that rivals that of the 'current' iMac Pro Vega 64/56. In the context of current iMacs, a substantial boost. eg. 5600-5700s as standard would make the rx580 seem very old hat. Add that to SSDs, more ram and 8 cores. The value of the current iMac improves greatly....but only in terms of bringing them up to date.
The real action? Is the imminent launch of the PS5. Why? Because RDNA2(?) and Ray Tracing come to that...and that means it's probably coming to an iMac Pro later this year. When you get 'that' level of performance whether it's good at gaming or compute is probably largely academic. It will be light year's ahead of what's in the iMac or iMac Pro. Any RDNA1 update to the iMac will be eclipsed dramatically by an iMac Pro with RDNA2.
My argument is that Apple should give the lower RDNA2 stack to the iMac (to bring it up to date and back to the future...) and have the higher stack for the iMac Pro. So they both have cutting edge performance.
And then it's a case of letting your wallet decide on the value case of a £1700-£3560 vs a £5k plus machine.
Hope that helps somewhat.
The value proposition. The proof will be in the pudding. And whether we can see what the iMac offers (be happy with that...?) and whether those with machines already, want to wait to see what the iMac Pro offers before pulling the trigger. Only then can we decide if the iMac Pro is worth the extra £1500. (But that £1500 could go towards buying a whole other machine, PC or Mac to cut the 'cake' (workload) in two.)

No kidding.
Vary rarely, though I did get my 24 inch iMac in a sale. (£1200-ish I think it was...and I plumped for some extra ram at the time...)

True. But they're going to get pushed when the specs improve and they occupy the former mainstream 'Mac Pro' price territory of £1500-£3k-ish.
And they should be able to hack it without 'jetting off to hairdryer' land.
It all adds up to doing something substantial in design and/or cooling. At the least, drop the iMac pro's cooling in there.
Otherwise we're paying for components that will be down clocked and thermally throttled.
