Alder Lake

Zen3+ won’t have any IPC gain. They will be factory binned parts to have slightly faster default clocks. Like the XT. I very much doubt AMD is spending any resources in refining the zen3 architecture for 7nm production. and if any refinement is to be gained, it will be for the Zen4 production.

Isn't Zen3+ rumored to be AM5 part with Zen3 cores and DDR5 memory controller?
Memory side of it could bring small IPC increase.

I think the memory boost will be marginal and will help with respect to latencies etc. But IPC gain in the architecture unlikely.

overall zen3+ if rumour is correct in terms of new socket and DDR5 adaptation then can have as much as those reported figures. Who knows

the Zen4 is interesting tho.

It will, DDR5 will have much higher Memory Bandwidth and lower latency, i think a solid 5% and 10% in gaming is on the cards from just moving to DDR5, that will put Rocket Lake back in its box.

DDR5 will have the same memory bandwidth and higher latency. Don't hold your breath for it ;)

The first DDR5 modules will be no better than DDR4-3200, while Intel's Z490 chipset boards support up to DDR4-5000.

That would be very surprising to me as it wouldn't it be expensive and time consuming to reconfigure a chip to use a different memory controller?
To do that 6 or 9 months before Zen 4 is out seems odd as it's not as if they need to try that hard to compete!
Maybe they are doing it to cover Alder Lake as that could be a better 8C chip than Zen 3 8C.
Seems unnecessarily desperate considering their general dominance.
Maybe it's all about catering for the gaming market which is a big deal for AMD.

AMD used to have their own foundries, they sold them, they are now Global Foundries.

The problem with having your own foundries is trying to keep up with the much larger commercial foundries like TSMC, as Intel are now finding out its extremely difficult and expensive, better to let someone like TSMC spend the tens of billions in R&D and buy from them.

Still there are lots of advantages to having your design and manufacturing vertically aligned as you can control the process, reduce costs and make the production more efficient.

AMD don't want to be taking their foot off the pedal, right now fighting Intel at every turn is exactly what they need to be doing, its about mindshare, people need to see AMD challenge Intel at every turn. And phonological warfare, Intel need to feel like no mater what they do AMD are right there with an answer for it, like everytime they punch AMD punch back harder.

Relentless, not an inch given.

That seems the main reason to do it.
If Alder Lake is the 'best gaming CPU' even for only 3 to 6 months, it plants seeds of doubt and they lose market share.
I'll only believe it when I see it though as still sceptical.
 
Thinking about it, having Zen 3+ on AM5 means that AMD will have AM5 CPUs on both 7nm and 5nm.
That gives them more flexibility to assign more wafers to AM5 chips which helps them role out the platform more quickly.
That seems like a very smart move.

2023 as earliest. Q4 2021 would be Zen 3 refresh Warhol.

Meanwhile:

Intel 10nm Alder Lake 16 Core & 24 Thread Desktop CPU Tested, 2.2 GHz Chip On Par With A Core i9-10900K In Engineering State
Intel 12th Gen Core Alder Lake Desktop CPU Spotted With 16 Cores, 24 Threads & 2.20 GHz Base Clocks (wccftech.com)

These GeekBench leaks are getting a little tiresome TBH, i want to see how it does in more real world applications.

I also hate the way WCCF put 2.2Ghz in brackets, as if to emphasis "oh its only running at 2.2Ghz and look how fast it is" 2.2Ghz is the base clock, in reality its more like 4Ghz which they do state in the text is the boost clock. its like putting 3.8Ghz in brackets next to the 5800X. Or 3.7Ghz by the 10900K.
