Frankly Nintendo would likely have been better off if they had minimal hardware input into their consoles for a good long while and were just forced into doing the industry standard type of thing, most of the major hardware decisions they made for their consoles through the 90s/2000s basically hampered the console rather than helping. Crippling the SNES CPU because they planned to have cartridge chip enhancements (like why not just spend a tiny bit to have a half decent processor in the system instead?), No CDs for the N64 (it never had to be cartridge vs. CD, you could have both as a cartridge slot costs dick all) and handing all your 3rd party support to Sony, mini-DVDs and a lunchbox design for the GameCube? Who thought those were good ideas? Wiimote was brilliant but for $250 the hardware could have been way, way better than that, the GameCube was $200 just 5 years prior and a huge upgrade over the N64, but they opted not to really upgrade the hardware much and by 2010 had a console that was really looking outdated and losing sales momentum when it didn't have to, taking 9 years to make a color model of the Game Boy? C'mon, etc. etc. etc.
And yet, outside of the SNES example (I'm going to reject the Wii one outright because I feel like it), none of these relate to the core processing of the systems, which, funnily enough, is where NVIDIA's input begins and ends on Switch 2.
And to suggest that NVIDIA didn't bother to create a tailored solution for Switch 2 when:
1. We
know it has marked differences to the rest of the Orin family (and
suspect further differences still in, say, node), including a file decompressor block that NVIDIA themselves will likely never have any use for, and
2. Nintendo is one of their most important customers, representing potential sales of 100+ million units, and previously singled out in earnings calls (such as in 2021) as a significant driver of revenue. It absolutely is worth their time and resources to invest in a custom solution. And that is
aside from the ancillary benefit of furthering the reach and ubiquity of proprietary technologies such as DLSS. And for that to mean anything, they need to deliver a hell of a chip that will entice third-parties to develop for it. Which isn't going to happen so much with some binned-down Orin scraps.
Yes, X1 was off-the-shelf. But we're not talking about that system. Even if we were, we can clearly see why Nintendo would have at least some requests for NVIDIA, considering the latter shit the bed with security in Tegra X1. Further, the proposal that Nintendo is now held hostage to NVIDIA's design would necessarily mean that NVIDIA is also
unilaterally specifying such things as RAM, cooling system, board design, storage media, battery (and battery life) all things that have significant impact on both the cost of the device (and Nintendo's own profit) and the realistic viability of the SoC, in the sense that there's no sense clocking it at a certain speed if the RAM can't keep up, etc.
And that just doesn't make sense. It really doesn't. It's Nintendo that's signing deals with Samsung, Hynix, Macronix, whoever, for all these things. They're not going to have a gun to their head while they do it, just like they're not going to let (say) Samsung sell them what Samsung want to sell them, even if it kneecaps Nintendo's ambitions for the SoC performance.
For all the talk about one company's brilliance and the other company's ineptitude, I can only note that one of those companies has had significant, major, and consistent success in the handheld console business, and the other has failed to create any viable native-processing gaming platform whatsoever. We know that the switchable form factor is a major factor in Switch's success, and we know that this isn't something NVIDIA could come up with, because they didn't. Because they were selling more than one Shield device for different purposes rather the converged device that the Switch is. It's also telling that Nintendo downclocked X1 in the interests of battery life. Nintendo absolutely know the portable gaming market. NVIDIA know graphics. It's the collaboration between, "This is what we need to do to make a device that will sell over the long term" and, "this is the absolute best possible graphical capability given the constraints you've dictated" that makes up the heart of Switch 2.
