The 3D Cache thing is an unknown quantity, its never been done before, it could be brilliant, it could just be ok and limited to a performance increase in games, only AMD know.
Yes. Its becoming clear Intel STILL cannot scale properly, it seems like their plan is to scale by adding more and more of these E cores, and this will get silly, it will get to the point where they have 3X as many E cores as P cores; still trying to convince people this is better than what AMD are doing.

The extra 3D cache will help software that does sequential operation on tightly packed chunks of memory, software that does random IO of large amounts of memory will not benefit much, if at all. Games do large amounts of sequential operations on tightly packed chunks as well as some random IO so should see some good improvements. The OS will also benefit so will probably get a small overall improvement.

Do you expect the 13900k, releasing next year with 24 cores, new architecture, improved cache, will not take the MT performance crown from the 5900X across the board? As well as improving on the 12900k's leadership in ST and some MT workloads already.
Nope, I do not expect this to occur.
It's possible that it *might* take the crown from the *next* AMD release. But comparing a chip against the second fastest chip of the release 2ish years ago isn't a fair comparison.
The 5900x isn't a fair comparison.
Well you would hope so as the 5900X will be 2 years old by then. Not sure the 13th gen is a new architecture though, think it is just a refresh. Problem you got is the 13th gen will be competing with Zen 4 which will quite probably have higher core counts then the current generations, be on a smaller node so have even better power to performance ratio, smaller I/O chip, 3D cache (assuming this) and probably other improvements to. I expect Zen 4 to beat 13th gen by 20% on IPC and regain the MT crown by introducing more cores which AMD can easily do (they will all be big cores to). Humbug has gone into detail more than once as to why Intel cannot currently scale properly and honestly it is not hard to understand

What would be at that point a 3 year old upper mid range CPU? yes. i do.
I expect AMD will continue to give Intel a tanning over the next 5 to maybe 10 years.
The Zen 3d CHIPS WILL REMAIN ON am4 yes, Zen 4 will be on AM5 though
Given that many here will say ADL isn't worth it over zen 3 Just based on the boards being more expensive yet with Zen 4 you'll have expensive 5nm Vcache CPUs which AMD will price way above Intel if they have a 20% IPC lead then the costly new X670 and also expensive DDR5 added on for good measure but with RPL You will likely get cheaper CPUs that can use older B660 or Z690 with cheap DDR4 so even if Zen 4 is faster that extra speed may not be worth the extra costs.
You are making to many assumptions, you have no idea how much Zen 4 or AM5 boards will cost. Also DDR5 should be cheaper then. Plus AM5 will likely offer several generations of upgrades. AMD tend to offer socket support a lot longer than Intel do. You seem a little obsessed with AMD pricing but seem to forget that this is teh first time for a long time Intel have actually offered value for money
Given Zen 4 will likely increase core counts, be on a higher cost node and have Vcache which will also add to the cost then if as you say it ends up holding a 20% IPC lead then there is no chance of AMD pricing it cheaply unfortunately unless of course Zen 4 flops and doesn't beat RPL.
The X670 will almost certainly release no cheaper than Z690 given they will share a lot of similar technology.
DDR5 may come down a bit but given the increased demand with AM5 I wouldn't be supprised if DDR5 shoots up to even higher levels than we're currently seeing considering supply has struggled to even keep up with Intels launch with only half the boards using DDR5 and with lower than expected sales.
fortunately Intel is here to save us lol. If Zen 4 meet all these expectations i will buy it no matter what, huge IPC increase, all big cores, better ddr5 controller, more advanced v-cache for even better gaming performance atop of IPC increase.

You do know that DDR5 chips aren't the issue though, its is the other components that are causing the shortage in supply. Every DDR5 module requires its own power circuitry (VRM) something not needed for DDR4, and Micron and Samsung have pretty much stated DDR5 isn't short in production, so once the other circuitry is in good supply then prices will drop. If anything the will be oversupply of actual DDR5 chips so spot prices will fall, and module prices will fall faster than predicted as they try to shift the excess stock.
I don't that's going to happen by the time Zen 4 is out especially given the increased demand that will also add and even then prices look to remain high for the next couple of years given the component costs that go into making them.

Well only time will tell who is right. The big factor you left out is even if these increased prices do come into play as you speculate it is still likely the AM5 platform will stick around a lot longer making it better value. For example i purchased my Crosshair Formula back in 2019, 2 1/2 years later it si still going strong and has allowed me to just drop in a 3900X and 5950X plus if i really want to (i don't) i can just drop a Zen 3D chip in. Pretty sure i could have done the same with X470 if i had wanted to also which would have given me nearly 4 years of use and 4 generations of CPU to just drop in. Now that is value for money, when was the last time Intel supported a socket for that length of time and provided 4 generations of CPU's to just drop in?
