Hello Freida,
There will be a full RDNA2 stack in time. The RDNA1+ is, therefore part of this stack launch in September.
It means higher clocks.
He's quite positive re: the 5700XT. It's a card that hangs with the previous gen 1080Ti!!!!! If it had launched a year ago on iMac? I'd have bought that model. No question.
With RDNA1+, it could eclipse the 1080ti, potentially. ( I think the 5700xt is around90-95% of a 1080ti.)
But the problem is. It's a year late on a Mac. And the only place to get it? Is a Mac Pro at £6000 plus the 5700XT as a BTO option which further increases the madness of accessing this card as a Mac desktop customer. Outrageous.
AMD Big Navi GPU has been decoded – at least 10 variants are expected. AMD Navi 21 For the past year or so, we have been hearing about Navi Refresh. For a long time those rumors have been treated with a certain amount of skepticism, but as soon as AMD themselves confirmed that they are […]

Here is the 5700XT1+ as part of the stack. 'Decoded.' It will be a little bit faster than the current RDNA1 5700XT. The longer this goes on, Apple will likely use this as BTO in the iMac. And marketing dicatates we won't get the RDNA2. They may reserve that for the iMac Pro. But with AS silicon muddying the waters....we can't be certain that this is the case.
ie. If they give the 5600M to the Macbook. We may get a custome 6700'M' (RDNA2) for the iMac.
It depends on what Apple offers. Last year's gpu tech' customised.
or. RDNA2 Progressive Raytracing tech' for the future. Cusomised.
What made sense in March or WWDC. Doesn't make the same sense in September. it's relative to what else the market is doing, the PC, teh PS5.
Apple charging 5 times the price of a PS5 for old gpu tech' vs a £499 RDNA2 based console. Sure. It's different markets. But we're on the cusp of new tech'. Across the board. AS14s...in iMacs. With cpu single and multicore that will turn imac 21 inchers and the mac minis into very 'old' looking tech' indeed. Throwing £2k at an iMac that has year old gpu tech' when the PS5 with RDNA2 is imminent is jarring.
And whilst some will throw themselves on Apple's altar claiming macbook keyboards didn't suck or that ipads don't bend or that iMac fusion drives are still relevant...I won't be one of them. I will say the RDNA1 is going to be sound news for the iMac. However, caveat. It's late. Apple will likely charge you £450 for it. More than the PC counter part...and I'll be impressed if it performs better in an iMac enclosure than a PC tower. And that £450 might be better going to a eGPU enclosure and RDNA2 in addition to the internal gpu. Especially if you do stuff like Maya. GPU rendering or 3d window stuff.
The least Apple can do this close to RDNA2 is offer a custome 5600 style 'M' for the iMac.
I'm a mac head. But I call out Apple when they say premium and don't do premium.
As for exact information on the RDNA1+ clocks. Probably 10% higher than the current RDNA1 is my guess. But it will be buried in Ray Tracing and efficiency and performance by RDNA2.
And that's the dilemma for iMac buyers. For Mac desktop buyers.
That's why I wanted my iMac to hold out until 'fall' this year. Because you could see that GPus, PCs, PS consoles etc plus the spectre of AS iMacs was going to form a cloud over any buying decision.
Hard to see, the future is...

He makes a great point here...which I feel is at the heart of the Intel legacy vs the Mac ARM debate.
'People confuse fast with smooth.'
And that's where the AS is going to give the Intel a sound thrashing. The beating of a life time.
ie. 3 4k streams. 10 million polygon shaded Maya scene....1080 Tomb Raider... 'Smoothly.' It's not always about raw monolithic speed.
See GPU future with chiplet future? And the SoC is where that kind of thinking is going.
It's about the experience. And Apple have chops in that regard. I have to give them that. That's why I 'do' Mac OS.
