The Steam Deck 30w cooler looks small and quite cheap.
Predictions that Nintendo will stick with 15w may not be as reliable as the old predictions that this generation PS5 and Series X will stay under 150w.

 Aren't most examples using the one with frame generation? 

The bolded isn't a certainty.

For example, if the Switch 2 has a Lovelace GPU (not totally out of the realm of possibility), it doesn't matter that it is mobile hardware, it will be competitive with the Series S and very likely exceed it in certain features (ray-tracing being one of course, Lovelace is just way ahead of RDNA 2 when it comes to RT, being newer and being Nvidia. Heck even Ampere is much better than RDNA 2 when it comes to ray-tracing.) So you might have a scenario where the Series S is a better rasterizer while the Switch 2 does ray-tracing better. 

And yes, while the Series S does support FSR 2.0, FSR 2.0 still isn't quite as good as DLSS 2.0. So image quality might not be that different either. A Switch 2 game upscaling from say 900p -> 1440p (using DLSS) probably would have better image quality than a Series S game from 900p -> 1440p (with FSR 2.0) and if they both target a locked 30fps, then the Series S having a better CPU probably won't matter much. Modern CPU's barely bottleneck at sub-60fps framerates, and the predicted Switch CPU (8 core A78AE) is a decent enough ARM chip that at those lowish frame-rates it wouldn't matter. 

I'd expect the Series S to be a much better system when dealing with high-FPS eSports titles, and other raster-centric workloads though. 

The Series S goes toe-in-toe with a GTX 1060 desktop GPU. I'd be surprised if the Switch 2 didn't come close to that level of performance, even with the low power-profile and small form-factor. That would be a 9 year old mid-ranged GPU by the time the Switch 2 releases. 

Does asus rog even beat the series S? from what i see they go toe to toe and the ROG is a beast with only 2 hours of battery life that cost 700$ lets be realistic here.

Does a ROG Ally run virtually every game on an XBox Series X ... yes it does. Who cares if it "beats an XBox Series S!!!!". It plays every fucking game the Series S plays does it not? Forza? Runs. Starfield? It works fine. Halo? Of course. It even runs the hilariously poorly optimized Star Wars: Jedi Survivor which is a next-gen exclusive and it runs it fine.

For people who want to say "well dur hur!!! I don't like it cuz it's not the exact same performance, its not the same rezolution and framerate!", no shit Einstein. You can bring an XBox Series X with you in your carry on luggage and try to play it on an airplane and look like a idiot, the rest of us are fine playing on a ROG Ally or Steam Deck 2 or Switch 2.

why are you so angry? the discussion here is it wont be that close to current  consoles graphics,  which is just realistic, no one is saying it won't run the games lol. Even current gen consoles are struggling u5 games properly 

This.  He said the switch 2 would run games like current consoles.  We said it wouldn't be comparable because of compromises.  He is now moving his original argument to EXACTLY what we have been saying.  

Soundwave in summary: moving goalposts 

A ROG Ally runs basically EVERY game that the XBox Series X does. Not just a few. Not a limited selection. Virtually every single game. Lets cut the bullshit on "next-gen games are magical unicorns that can't possibly run on portable hardware". Yes they can. Unfortunately for you guys Youtube exists and everyone and their grandma that owns a ROG Ally is uploading videos of it running Starfield even without optimization patches that are coming in the future and it's entirely playable and looks fine even unoptimized.

Is it the best looking version of the game? Of course not, you'd have to be fucking idiot to expect that. But it runs fine and it is the same game, not like some N64-ized version of it.  

How is it not "comparable"? What does that even mean? The PS4 version of FF7 is completely "comparable" to the PS5 version. It's the same damn game. A lighting tint difference or some mist doesn't make it "uncomparable", what the fuck kind of logic is that?

When plugged in and at the highest power profile, it gets close. Starfield on the Series S runs at 900p -> 1440p likely the PC equivalent of low-medium settings, locked 30fps. The ROG Ally at 30W TDP can do variable 35-40 fps 720p -> 1080p with FSR 2.0 at low settings. 

That is on an open-platform too, with the Series S getting closed-platform optimizations.

An RDNA 3 mini-PC like the Minisforum UM780, which has a higher power profile than the Rog Ally and better cooling, is roughly on par with the Series S in the game. Here is it playing at 1080p native low running at 40fps+.
