Actually current CPU is biggest bottleneck of Switch. Of Course that PS5/XB2 will have stronger CPUs but Switch will also have much stronger CPU, I mean we already have announced ARM A76 CPU thats miles better than A57 (after A57 we have A72, A73, A75 and now A76), who knows what we will have in around 5 years period.

Goes without saying that the Switch 2 will have a stronger CPU.
But Ryzen is in another league entirely to ARM's offerings.
And just because ARM has an A76 core on the market, doesn't mean the Switch 2 is going to use it... Why? Because nVidia might build another SoC that is based around Denver.

Also you need to realise that A57 in Switch was clocked only at 1 GHz and using only 3 cores, so imagine just how about much difference we would talk if Switch would just use A76 clocked at 2GHz with more available cores than 3. But of course Nintendo will not use for Switch 5 years old CPU (assuming Switch will be launched in 2023.) and they will use in worst case around 2 years old CPU like they did with Switch.

Still won't hold a candle to Ryzen.

It has 4 but only 3 are available for games.
Thats not hole story, A76 can also clock more than A73. Zen 2 will maybe have 3x higher IPC than A76, but A76 is 2018. CPU, Switch will most likly using ARM CPU from 2021/2022.
Thats not true, A76 can already go to 3GHz. Switch has 20nm chipset, A76 is already making in 7nm, that means that Switch 2 will most likely have 7nm chipset at least, and there is huge difference betwine 20nm and 7nm only if we talk about same CPU or GPU, not mentioned next gen and improved CPU/GPU with 7nm. So yeah, Switch 2 will most likely have more CPU and GPU cores than current Switch has, with higher clocks also.
2015. tech architecture vs 2012. tech architecture. ARM is most used CPU in world, most popular tech device (smart phone) on world in most cases works on ARM CPUs, mobile CPUs have much more space for growth than any other CPU.

Just because it can clock higher, doesn't mean it will.
Nintendo may have a preference in downclocking the CPU in order to bolster the GPU side of the equation, mobile devices need to keep power consumption check, doubly so for one that is dedicated to gaming.
Either way... Don't see 3Ghz being the norm for ARM chips anytime soon, ARM's claims of 3ghz chips before have never really materialized.

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.
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.
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.
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, 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.
