I won't get my hopes up just yet. Want to see what the developers can do after they've had much longer with the dev kits first.

Yes DLSS requires more resources than just rendering at a lower resolution but the whole point of it is it takes less resources rendering at a low resolution and upscaling compared to rendering at that higher resolution in the first place. If it didn't there would be absolutely no reason for it to exist because of upscaling artifacts and frame timing issues etc. It's a free lunch compared to rendering at a high native resolution. It's quite possible the chipset for the Switch 2 has some functionality which optimises and reduces the load of DLSS upscaling on the main system anyway. When the Switch came out it was unknown whether it would succeed and the Switch basically had a slightly cut down and downclocked version of the standard Nvidia X1 but now Switch 2 can have more effort put into it with the expectation of high sales. So they can afford to design in more new features even if ultimately they want a low price for each manufactured unit as Nintendo like high profits from hardware even on day one.

That said I'm still expecting it to be a very capable unit but I think there will be a greater distance between docked and portable performance level than the original Switch. It will be a better home console in comparison to the portable side. We shall see but there is so little power going into the portable side maybe 1/4 of the power or maybe less. I can't see how the console can create 1080p 120fps visuals without heavy use of DLSS upscaling.

Ultimately very happy to be proven wrong though.  

According to a Korean outlet thelec, the Switch 2 is on Sammy 5nm. Not sure about the source, but if true would make sense given what we've seen with regards to performance-per-watt.

Functionally that is an acceptable level of compromise given the enormous gap between the Switch 2 and modern PC hardware - a good GPU's shaders already idle 80-90% of the time with ShadPS4, for instance. The main issue will likely be how to handle its interactions/requests to other system modules.

I'd expect the docked CPU will be the slowest component and need a lot of HLE hacks to work at first... though I'm not sure how heavy or not ARM emulation is in C++, to be honest, especially with SSE/AVX support. Apparently ARMv7, at least, runs well.

5nm Samsung would make some sense for sure. 

Apparently SuperMetalDave64, the Youtube Nintendo fan says Digital Foundry counted pixels and Metroid Prime 4 is 4K native 60 fps on the Switch 2. That's pretty darn impressive if true. 

It also hits 1080p/120fps in performance mode apparently.

On Switch 1 it's 900p/60fps, so it's about x6 higher res in 4K mode on Switch.

Split Fiction (PS5/XSS next-gen only title) compared on PS5 Pro Vs. Switch 2

Interesting comparison. Sometimes the faces feel like they look sharper on Switch 2, but overall with background and texture you can see they are less refined on Switch 2.

Before they ran the side by side and slow mo comparison and just played each footage one after another they did feel very similar. So a good effort on Switch 2 that many won't even care there is a difference.

Looks good here in single screen comparisons, the actual split screen gameplay looks a lot blurrier on Switch 2 though but that's not featured here.

I think Starwars Outlaws will be the first proper indicator of how the average current gen only game will fare. We have Wild hearts too but that game was already a fuzzy mess on PS5/Series X

Borderlands 4 is another current gen only console release that's hitting Switch 2, and an Unreal Engine 5 title as well, like Split Fiction.

The footage of that shown in the direct, assuming it was Switch 2, looked very solid.
