Truthfully many of the 'it will be 8nm' remarks I have read are also assuming the worst about battery life and performance as a consequence, with the framing that Nintendo are willing to give those up for a less expensive node. They are not really taking into account any power saving tech but the notion of 'this is worse in every way but Nintendo doesn't care'. I don't give them as much benefit of the doubt as I do your thought process.
I don't think most people (excluding all of my friends here on Fami, of course) are engaging in any intellectual honest way, no matter what "side" they're on. The 8nm Jets with "because Nintendo, lulz" nonsense up against the 4nm Sharks with their "My high school bully plays
Call of Duty but this will finally show them" console warring.
There is an argument to be made that sometimes Nintendo delivers overpriced, under specced products because they think they can leverage their fans to pony up anyway. But the one thing we know is that Nintendo absolutely could have gone with a smaller chip. Drake is unusually big, so whatever they're doing, it's not that.
Gaming is at an all time high, but studios are closing, people are losing their jobs. Their families are at risk, and the Art - and I believe games are Art - that they could have made is being flushed down the toilet. That might seem like a tangential rant in a discussion of process node, but the reason these things are happening is because of a corporate console war that has treated it as a scorched Earth zero sum game.
When you buy a console that
doesn't make money, Sony and Microsoft are betting all those studios - all those employees, the very existence of their games - on "winning" the console war, getting you to buy a console that they couldn't afford to make, and then soaking you later when they have a monopoly on the market. They were willing to dangle treats in front of gamers, because they were betting they could fuck them over later, and the risk was to their employees, not to themselves. It's not morally superior to overpricing a luxury item, it's worse.
We should be wanting Nintendo to prioritize a sustainable product, both in the environmental sense, but also in the sense of "making the market sustainable long term" because it's what's ethical and it's what's best for gaming. 8nm would be an incredible choice if Nintendo could make it work, it would be something akin to "lateral thinking with withered technology" if Nintendo/Nvidia could find a way to squeeze an extra generation of handheld dominance out of an 8nm die.
And the reason to believe they
didn't isn't because they prioritize bleeding edge performance, but because they
don't, because 4nm is a path to offering what we all assume Nintendo wants to deliver, a compact device with great battery life, the very thing that all their PC handheld competitors have not been able to truly do.
I get invested in my analysis sometimes, and get... over involved in defending my ideas. I admit that, and I try to be sympathetic to others who do the same. But if you've got some emotional investment in winning the console war, you're not just fiddling while Rome burns, you're pissing in the eye of the folks with the buckets. Grow up.
Fake edit: just to be clear, this rant (which sorta poured out of me, sorry about that) isn't directed at you or (for the most part) anyone else on Fami. I came to gaming as a grown man, and I shouldn't be surprised that some people, when engaging in a hobby they've had since childhood, still think in the terms they did when they were younger. But it's a perspective I've never been able to wrap my head around, or be especially sympathetic to.
