Ryzen is another league, but Switch 2 will be most likely released 2-3 years after PS5/XB2, so must likely we will comparing newer ARM CPU compared than Ryzen in PS5/XB2.

And in 2-3 years Ryzen will still be in another league.
There is such a massive performance delta between the latest and greatest ARM socs and high-end x86 parts it's ridiculous, that gap isn't going to close in just a few years.

Well that assumption, but with point that Nintendo already using ARM most likely they will stick to ARM with Switch 2 also. Nvidia itself said they will have partnership with Nintendo that will last at least 20 years, we talking about very strong relationship, so it's very possible they will make custom SoC for Nintendo needs where Nintendo will choose what they want.

Perhaps Nintendo will choose nVidia again.
However, nVidia's ARM CPU efforts aren't anything to write home about.

We dont know that, we dont know how strong ARM CPUs will be in few years. Like I wrote, I expecting in any case that PS5/XB2 CPU will again be stronger, but that Switch2 will have comparible CPU for its need, in this case that runs 4K PS5/XB2 games at 1080p at least in docked mode.

I have a fair idea as I have been following ARM CPU development... Along with the likes of PowerPC, MIPS, x86, SPARC, Transmeta, OpenRISC and so on just to name a few.
ARM CPU development will continue along it's current roadmaps and general yearly improvements, that goes without saying, no one refutes that.
But the part you are missing is that... Current generation consoles are using Jaguar. - Which is an evolutionary update to Bobcat, this was AMD's absolute worst CPU at a time when AMD's entire CPU lineup was absolutely horrific, their fastest was hot, slow and a waste of time... Which hopefully puts Jaguar in perspective of how bad it is.
And Jaguar still gives the ARM cores in the Switch a run for it's money.
Roll on to today and AMD now has Zen, this fixes AMD's performance deficit from top to bottom, ARM isn't even in the same league anymore, ARM is still being compared to Core 2 Duo's, Jaguar and Intel Atom, let alone Zen, it will be years before you mainstream ARM chips can even think about hitting that performance level.

We can bet they will have higher clock than current 1GHz, Nintendo preferred lower clocks because they couldn't had higher currently, in this case we most likely talking 7nm vs 20nm if comparing Switch 2 and Switch.

Yes they could have had higher clocks this generation.
You forget the Switch SoC is old. - It's built at an ancient 20nm fabrication process, that is the reason for the lower clocks.
If it was built at 14nm/16nm though, there is still no guarantee that Nintendo would have increased the CPU clocks above 1ghz though, Nintendo might have spent all of it's extra TDP budget on the GPU side of the equation, maybe then the console wouldn't have games under 720P so often.

Yes, 3GHz still didn't used for ARM CPUs in devices, but 2.5GHz is used, I dont see why will not see 3GHz also used in few years. Also even Switch uses 2GHz with much more modern and stronger CPU with more than 3 available cores for games, compared to current Switch CPU, we talking about huge difference in any case.

What?
|
Ryzen will still be in another league, but future ARM CPUs will be stronger than current ones in any case.
Its almost certain that they will chouse Nvidia + ARM also, they were clear they dont want to have different tech/archcture every new gen, and Nvidia very confident said their partnership will last at least 20 years, it obivous they have plans for future, and its not hard to imagine they making some custom SoCs for Nintendo instead using just available on market like they did with current Switch.
Difference is that Jaguar in PS4 is 8-core CPU that runs at 1.7GHz while A57 is 4-core CPU that runs at 1GHz. If I recall, A57 vs Jaguar core vs core on same clocks had similar results in benchmarks.
PS5/XB2 will have huge update in CPU, but possible Switch 2 will also have huge upgrade in CPU side in any case, I mean if just now curently imagine for instance A76 6-core CPU running at 2GHz compared to current A57 4-core CPU runing at 1GHz, we talking about huge difference, and Switch will most likely using more stronger and more advance CPU than latest ARM CPU for potential Switch 2 that would most likely be released in 2023, and that would be most likely enough to runs 4K PS5/XB2 games at 1080p at least in docked mode.
No I didn't forget, I actually wrote its 20nm, and 20nm is reason why they couldnt go with higher clocks, higher clocks with X1 thats 20nm would mean higher heating and less battery life.
If they for instance used Tegra X2 you can bet they would use higher clocks for CPU and GPU. Biggest bottleneck for Switch is CPU not GPU, and that was obvious from day one.
I think I was very clear with my last paragraph in my previous post, but if you dont think like that, what exactly part isnt clear?
