Just for context, this is the heat-sink on the PS5. 

And the fan. 

This is what the heatsink on the Steam Deck looks like. And below it you can see the fan. 

PS5 maxes at about 197 W total power consumption, and averages around 100W in games. Steam Deck maxes 45W. Both PS5 and Steam Deck are on 6nm process node and started on 7nm with their original models.

On average, with each die shrink we're seeing about 15-30% performance gain per watt. Assuming 20% on average, it would take about four die-shrinks to get average PS5 level of performance in a Steam Deck form factor when it is maxed out plugged into the wall. Assuming a docked Switch 2 pulls about half of that at max it would take something around six or seven die shrinks. Now of course, in reality there are also new innovative architectural gains that surpass just the efficiency gains from shrinking the die, but if you wanted PS5 level performance in a 20W package, you'll wait almost a decade from release. Shouldn't expect anything like that until 2030 at the earliest. For a 45W package you could expect that around 2027 maybe. 

There are other considerations of course (ARM vs. x86, Nvidia vs. AMD), but roughly that seems about right given how we've seen performance gains in the past, and how advancements have slowed down with Moore's Law also slowing. 

Obviously, Nintendo was never going to go "cutting-edge" with Switch 2 but settling on noticeably dated tech would also be a mistake. This actually sounds pleasantly surprising and better than expected, judging by most of the comments here. All things considered, it sounds to me like Nintendo has gone fairly "modern" for this form-factor's performance and it should prove to be one of the biggest (perceivable) jumps that Nintendo has made from one system to the next.

Just to add a bit of context for the people in the thread (and you probably know this), most of those games are accurately described as barely playable on PS4/XBO, but SF6 runs well on PS4, since fighting games basically have to run at a stable 60fps, or the framedata of the moves get messed up, etc. Which makes it more difficult to port to weaker hardware since you can't cut the framerate in half like you can with most games.

Well, the way I see it is that not all leaks are equal.
It's one thing to have a random post on 4chan claiming something, and completely different when its coming from someone with an impeckable track record.

The Nvidia leak for example has proven over and over to be correct as more and more games that were on the list keep getting announced.

Midori on Twitter with Sega/Atlus leaks is another example.

In the case of the reports of Switch Pro being planned, but then cancelled (presumably due to the semi conductor shortage at the time) this was corroborated by several reputable outlets, but in particular by Digital Foundry / Eurogamer.
They were the ones who first broke the news on what the original Switch concept would be, and its specs. They did the same for PS4 Pro, and were spot on again, etc.

That said, I don't recall what the specs were supposed to be for Switch Pro, if they even mentioned any. It's possible that the specs mentioned prviously in this thread came from a different source, and should not be mixed together with Digital Foundry's report in that case.

Best thing EA did was not bother trying on Switched. Saved me money on my other systems and ignored their micro transaction infested games.

EA is still stinking up the joint with FC '24 (I keep calling it FIFA) on Switch, but there are actually a few smaller games released in a decent state worthy of  respect like It Takes Two and Tales of Kenzara: ZAU.

Not sure if anyone replied, but they did sell the original 3DS at a loss after the price cut, and if memory serves even the WiiU was sold at a small loss at launch (Don't ask me how lol). But I don't expect this to be the case here.

My only complaints about the Switch are the low quality joycon sticks and the power. If this is truly substantially more powerful than a PS4, it's looking like a great start.

I'm confused as to why this would be sold at a loss this isn't a steam deck which only sold 2-3 million in 2 years. If the rumored specs are true we are looking at basically a cut down version of a 2050 a gpu released in 2021, I'm sure Nintendo got a sweet deal considering the switch sold 140 million So the chip will be mass produced for nintendo.

woah now.... lets not get too ahead of ourselves :P 

4090 performance for Switch 2 should be more than enough. :)
Could you imagine a 500 watt tpd handheld?

(also isnt a stock 4090 like 83 tflops? of fp16.... did you overclock that bad boy?)

Switch 2 needs to use hall effect joysticks.
