How will be Switch 2 performance wise?

Not a leak. It's an unsubstantiated rumor. We need to start knowing the difference, otherwise people start to peddle rumor as fact.

• TSMC N4 node process (4 nanometre?)

TSMC N4 node is advertising. It's NOT 4 nanometer.

TSMC N4 is actually based on it's 5nm technology which ironically has a bigger gate pitch and interconnect pitch than IRDS 7nm definition, take that as you will.
But the scaling just isn't happening at the moment.

GA10F does refer to a Geforce Ampere class GPU.

• 12 stream multiprocessor GPU, performance ranging from 3.5 to 4.5 TFLOPs docked and 1.7 to 2.0 TFLOPs handheld

Teraflops is meaningless. It's theoretical, not real-world.

720P again confirmed? ;)

• Memory cache specifics uncertain, Tegra GPU cores may be able to access CPU cache

This has been a Tegra feature for some time.

Cache coherency is however, only 1-directional, Tegra X1 in the Switch should be able to do this.

Good luck getting 1080P happening with 100GB/s of bandwidth.
You will not get the fillrate necessary to drive that.

• Cartridge specifics unknown, but 3D-NAND may provide a cost-effective way to significantly increase storage

And will not last long.

Bitflip is a big issue with NAND, you loose data extremely quickly.
3D NAND would exacerbate that issue.

ROM is the way to go.

Steamdeck gets away with it because it's only running 720P levels of resolution.

Keep in mind that Delta Colour Compression is a technology that the Playstation 4 lacks, so that can give Tegra an extra 60% bandwidth boost if the patterns fit with DCC.

Playstation 4 level of capability but with a few extra tricks (Ray Tracing) is the most logical scenario here.

Iphone 15 pro Max, looks like it would need like 4 times its current performance, to match a base PS4 (in this game).
However.... that is still insane.... its a PHONE..... its not ment to be able to match a console, that again, draws 100's of watts of power.

Keep in mind is also running CUSTOM silicon and CUSTOM software to MAXIMISE performance.

You do NOT get that same privilege on other platforms.

You do realise that is exactly what console developers so? Essentially just move a slider?
Digital Foundry does it all the time and "adjusts" PC sliders to get an identical visual representation of the console release and gets those games running on equivalent PC hardware.

Personally, I'm expecting it to be a lot more powerful than a PS4, just like the Switch was way ahead of the PS3. It won't be as powerful as the PS5, but the power gap between the Switch 2 and the PS5 will be smaller than the power gap between the Switch 1 and the PS4.

It doesn't need to match PS4 specs to beat it.

"weaker" hardware on paper today is leagues ahead of "faster" hardware from 10+ years ago, efficiency does actually improve, which is why the Switch is able to beat a Playstation 3, WiiU and Xbox 360, nVidia Maxwell is just a significantly more efficient chip despite the "flops" not representing that visual leap.

Why would you ever run any game at native resolution on Switch 2 to begin with? There's no point when you have DLSS, undocked really never needs to go above 540p as far as I'm concerned. Yes native looks slightly better, but not good enough that it's worth forcing the system to render 4x the pixels. On top of that DLSS gives you basically a "free" form of anti-aliasing. Running at native + wasting resources on top of that for AA is just brain dead, in fact I would postulate that DLSS implementation is the automatic default for Switch 2 dev kits, the system will be designed to run with that on. 

Especially on a freaking small 7-8 inch-ish display, the regular joe, even most "game enthusiast joes" are not really going to know or care that their game is actually only rendering from 540p, shit I think you could go even lower than that. 

Yes you can move sliders around on PC games that have a performance overhead to "match" lower console settings, that doesn't really have anything to do with what I'm saying. I'm saying if the Steam Deck version of Ratchet & Clank runs at 30-40 fps, if Insomniac sat down with a team of 20-30 people who worked on the port for 6-7 months JUST for that one hardware, do I think they could get that up to a solid locked 40 fps and/or maybe even bump the settings from Low to Medium 30 fps ... yes, I do. Optimization does matter.

540p or less native scaled to 1440p or 4k is going to look terrible on a big TV.  You seem stuck talking about how games will look on a small screen....  the switch 2 is a hybrid and needs to look good on a large TV, not just 8 inch screen.

If it helps I agree on a small screen the pixel density is good enough where low resolution and low settings is fine.  Docked mode is the issue when comparing to the ps5.
