Around PS4 performance when portable.

Around PS4 pro performance when docked.

DLSS will bring performance between Series S and X.

For games that are not CPU bound, it will be close to X.

That sounds like wishfull thinking to me.
PS5 and XSX use upscaleing too, like dlss isn't going to magically make a handheld useing 30-35watts equal to a series X or PS5, pulling 200 watts.

I wouldn't expect much beyound PS4 base level, and with DLSS maybe PS4pro range.

I would be surprised if a Switch 2, matches a Series S, in like for like graphics settings and resolution, in a more demanding 3rd party game.
Does this matter though? The step-up from a Switch, to PS4pro level, will mean all Switch games, can run 4k upscaled (if nintendo choose to do so).

Nintendo does great looking games, without being super demanding, because they dont chase realism.
They simply dont need all that hardware power, if it comes with drawbacks (price, weight, size, powerconsumption ect ect).

This exactly.  DLSS isn't magic nor is upscaling new.  

The idea the switch 2 is going to match current gen consoles is laughable.  

I'm even more confident after seeing how poorly Apple's magic chips do with modern games.

It might have been better to say that the game with ray tracing rather than CPU bound.

RT is God awful on consoles. Looks great on PC but is a fps killer. I don't see the switch 2 handling RT well. My rtx 4070 is ok at RT. I lose 30% fps with RT, sometimes more.

It won't handle it well but since it'll be using an Nvidia chip with more recent architecture it'll probably be pretty competitive with RT compared to the PS5 and Series X at least. Splatoon 4 can maybe do something with it for the ink.

I said It in the past and i will say It again. On Paper Switch 2 Will be closer to PS4 pro, but battery + Nintendo conservatism will make It run at a very low clock, so It will peform just a little above PS4.

Also prices at $399.99

If by power, we mean what level of performance will it deliver? Likely something between PS4 and Series S in terms of graphical features and prowess. Third parties will treat it as a 30fps/720p (or even lower) machine, but the image resolve will be anywhere from 900p to 4k depending on the game/developer. Visual feature set will be closer to the Series S compared to the PS4. PS4 Pro keeps being brought up but that's just a PS4 natively running games at 1440p, Switch 2 will be doing things you will not see onPS4 Pro albeit at a lower internal resolution.

Put Nintendo in charge of a PS4 level device with Nvidia's modern feature set and I'm sure we'll be getting plenty of stylised games that won't out of place on the PS5

There's no such thing as "PS4 level power" ... it's irrelevant today, I'm not sure why so many of you can't understand that PS4 power is only relevant to a system from that time period using that exact class of chip (GCN2 era chipsets which are ancient).

The moment you're talking about architecture that 3-4 generations ahead of that, the comparison becomes meaningless because modern chips can run modern engine games a PS4 can't.

Also not sure why people here fixate solely on consoles, the more relevant comparable may well be the Steam Deck, the Steam Deck runs almost every PS5-era title. Now you can whine and moan and gate keep all you want about you refuse to play games at this setting or this frame rate, but you don't speak for everyone or even close to everyone, it's like those audio elitists who look down at every sound bar because it's not a proper giant sized set of speakers. Like no one cares. Also those games on Steam Deck are not even really optimized specifically for the Steam Deck hardware, they're just PC games with settings sliders changed a bit, the Steam Deck would be able to run all those more demanding games better if the developer actually sat down with a full dev team and spent 6-8 months specifically optimizing just for Steam Deck hardware like console ports have the benefit of. This is a huge, huge difference, people are stupid if they're just going to hand wave that away. With better optimization pretty much all of those more demanding Steam Deck games would be able to run at a higher frame rate and/or resolution/effects settings. 

Steam Deck and now ROG Ally are basically their own class of machine. Engines are much more scalable today and comparing to devices that have no internal fan and are pocket sized like an iPhone makes no sense either. Switch 2 is a tablet sized portable with an active fan, it's more logical to compare to a full size iPad and a full size modern iPad would be able to run lots of PS5 games if developers wanted to port them. And even there iPads don't even have the benefit of active cooling and a "docked mode" when connected to power which the Switch 2 will have, they have to run off passive cooling all the time. 

The power of the chip is not the issue on those devices, it's the size of the system (bigger = easier to cool) and whether you have an active fan or not, the chip in the current iPhones can perform a lot higher if it was allowed to run at full performance and had active cooling.

All I know is you hyped the iPhone as something the big three should be afraid of.  And it turns out the iPhone and apple's magical chips run games sub ps4 level...  not sub ps5 level.  Not sub ps4 pro level.  But literally RE4 is hot garbage on the iPhone and doesn't touch the fidelity of the base ps4.  And here we are with hyping of mobile hardware yet again.  

Modern consoles are far more powerful than you give them credit for.  If you don't care about graphics and framerates, that is fine.  But there will be a massive gap between the fidelity of the ps5 and switch 2.
