8 nm would be interesting. Consume more energy, less efficient, generate more heat and slower.... we shall see soon enough. But if true, expect downclocking speeds.

The discussions here have ruled it out long ago. https://famiboards.com/threads/future-nintendo-hardware-technology-speculation-discussion-st-read-the-staff-posts-before-commenting.55/

Stop using fake and/or 2 year outdated information. With 12 sms, it would be terrible inefficient at 8nm. It will be 5nm.

Lol i don't care what some Nintendo fans on a Nintendo board with wishful thinking have to say. To me 8 inch screen plus koplite sayingits 8nm and df saying it's the most likely scenario plus the leaked documents saying saying 8nm means it mostly likely will be a 8nm but hey if I'm wrong I'll eat crow and  but I hope you are prepared to the same.

So you don't know if Kopite "does this for a living." All you know is that there is buzz around their leaks and that they are often (but nowhere near always) accurate. 

There are many reasons to add an 8 inch screen that have nothing to do with wanting a bigger device because you use an inefficient process node. 

Switch's aren't necessarily pocketable, and batter life is much more important to portability. A larger device allows more battery real-estate. Many complaints from the Switch's mostly adult male users was that the size was too small and cramp. 

One notices that other portable gaming devices are much bigger than the Switch. And Nintendo can always release a Switch 2 mini or lite for the children demographic. 

I think now that the switch 2 will be closer to steam deck performance

Other portable devices are bigger but switch is destroying them in sales along with being extremely dated tech. Think about it for a second and how Nintendo works they could have easily made oled switch 2  with a 7 inch screen and really fixed the biggest gripe with the switch which is the lcd screen but you expect them make  the screen bigger because a few male gamers complained when the Switch is probably gonna end up the best selling console of all time. A big bulky device is not gonna be good for sales but with 8nm they have too and they will release a mini and oled screen a the smaller chip in 2 years.

We have no idea how Nintendo works under Furukawa, hardware under Iwata was very different from hardware under Yamauchi. 

A huge complex chip is nothing like the Wii, Wii U, DS, 3DS, etc. either, that whole line of logic goes down the toilet at 5nm or 8nm it doesn't matter. Those old Nintendo systems were compact, low power, and yes cheap devices. This chip even at 8nm wouldn't be that. It's a huge chip, almost the size of a XBox Series S.

If Nintendo wanted to be cheap they would have used 8SM max, even 6SM probably.

The Nvidia leak says nothing about 8nm either. It says 12SM ... 12SM is shit ton of graphics cores and frankly way overkill for supposed "PS4 only!" performance. This is not going to be a cheap system.

Why they are using so many graphics cores on such a massive chip is a giant question mark right now, if we believe its 8nm. It doesn't make sense from even a cost perspective, you could easily cut the system down to 8SM and have PS4 performance if that's all you wanted to do and saved money. 

If having a small sized form factor mattered as much as you suggest (i.e. it is the reason why Nintendo outsells handheld PC's*) then Nintendo wouldn't go with an 8NM chip. They don't "have to" go with the chip if they think it is a burden to their sales potential. 

Again, battery life matters more than a slightly bigger size anyway. People want handhelds that last longer between plug-ins, not necessarily pocketable ones (which the Switch isn't.)

*It is not the reason why Nintendo's platform sells better. Exclusive titles and price are.

It doesn't really even make sense cost wise.

Why even use 12SMs (1536 graphics cores) but then really not make much use of the graphics cores because you're going to clock them ridiculously low (like maybe 400 MHz docked? 200 MHz undocked?).

You could get the same performance from 8SMs (1024 graphics cores), clocked them a bit higher and have saved money.

If you were interested strictly in making the cheapest system possible, you're paying more for this absurdly large (at 8nm) chip for no real gain. Tell me again how this is the same as the Wii, DS, 3DS, etc? 

Digital Foundry also believes The Matrix Unreal Engine 5 demo on the Switch 2 did indeed happen, so if you're going to accept everything they say as gospel, guess you have to accept that one too. 

It would quite literally be easier to use 8 sms at higher clocks to achieve the same or BETTER results as 12sm on 8nm.
