A couple people here are forgetting that it is surely going to be another handheld system.

A handheld is not going to be at the spec level of consoles that released 4 years prior. And yes, expecting it to be at or perhaps slightly above an 11 year old console is about right. But of course it'll have much more advanced stuff in it than an 11 year old console (in fact more advanced than the 4 year old consoles), DLSS is one example, that may put its actual output in the PS4 Pro area.

A reasonable expectation is that the actual output will be above PS4 for sure and maybe just under PS4 Pro. Said another way, expect the gap between handheld Switch2 and the consoles to be moderately smaller than the Switch-to-console gap was.

This is fair and likely accurate.  People are crazy if they think a 15 watt mobile device is matching the ps5.  

'The switch 2 will have mobile hardware and will not push ps5 visuals.' I think this goes without saying (to sane people anyway).

The iPhone pro is limited by power draw & thermals, it is handily outperformed by the steam deck which on paper has a less powerful chip.

Would you agree that the Switch 2 is likely to be more capable than the Steam Deck, in docked mode at least?

If yes then I think your point re. 3rd parties isn't really supported as Steam Deck runs a tonne of modern titles... If the Switch 2 establishes a decent install base, which seems almost guaranteed at this point (unless Nintendo completely shits the bed), then titles will also be more optimised than on SD.

Yes, games will look better on the home consoles but that also applies to Steam Deck - developers are still spending resources on optimizing around the SD specs for a reason.

Oh yeah, for sure the switch 2 will outclass the steam deck.  No doubt.  And for sure the switch 2 will be able to run modern games, no doubt.  Just not at the fidelity and performance of the ps5.  And most people won't care about the fidelity differences.  So switch 2 will be fine.  

Expect it to be around the PS4 (probably bit below).
With DLSS for upscaleing though, it will play games slightly better than a base PS4.
(while consuming like ~20watts)

That roughly translates to about 4-5 times more powerfull than the current Switch.

I would not expect more than that (it depends on how big, heavy, and pricey nintendo want to go though).
(if its more powerfull than I expect, then its bound to be heavier, bigger, and more expensive as well)

I expect the rumored specs to be true as its from a nvidia hack. 8x A78c cpu cores, 128-bit bus and 1536 ampere gpu cores on samsung 8nm.
But I expect the clocks to be much lower than what most people expect, 1.5ghz for the Cpu and around 450mhz for the gpu.

That gives about 0.92TF in handheld mode and probably 2x dock mode, Even though it's a modern gpu architecture it has ampere TF so around 0.5x the performance of ps4 and around the same performance in dock mode.

Nintendo fans will probably be dissapointed with the new switch but keep in mind rdna2 which steamdeck is based on is more efficient than ampere and that console is big, clumsy and has 1.5 hour battery life.

...which was over 10 years old by that time, too. And it was more powerful despite the possibilities of the Cell chip. And most in this thread agree that it will be a bit more powerful than the PS4.

Blazer, on the other hand, expect the successor of the Switch to "wipe the floor with the PS4 Pro" in raw power, which is just unrealistic if it retains the hybrid form factor of the Switch.

Surprise!

Switch 2 is a laptop, and is now more powerfull  than a PS4pro :)

just kidding.

I fully agree, nintendo needs to keep it light weight, low power consumption, low priced as well.
That just doesnt lend itself to easily going beyound where the PS4 is, for a handheld dockable device.

The Switch had four and a half node shrinks vs. the PS3, though, compared to just two for the Switch 2 vs. the PS4, maybe three if they go for the N5/N4 node. There's a huge 2.8 to 5.6-fold difference there.

Of course, the PS4 was kind of underpowered when it launched while the PS3 was the opposite except for its RAM. Or the Switch 2 could consume a bit more power. than the Switch.
