You can be specific about what part you disagree with. A fourm is about discussion, after all.
I was gonna respond, but what you are saying is so FAR removed from reality that I didn't even know where to begin.
eg.
The major issue with PS5 is that the IP on the chip is terrible. It's Zen2/RDNA2 on N6, both offer terrible perf and features/area.
first of all, PS5 launched on 7nm, not 6nm. Secondly, at the price point, fab process, chip size, you couldn't possibly have made a more powerful console in 2020 than what Sony did, and in part, MS. Both approached using the best hardware they could at that price point in slightly different ways. And the entire industry actually commended sony on their lean and efficent design strategy, and the benefits of that has been showing itself all generations so far.
Also, you also need to look at what you can get for the same money, what other $400 device from can match what the PS5 could do? None? Then you can't possibly say the stytem design was flawed.
This is because sony pursued a "commodity maxing strategy" where they made up for the bad performance/area by packing cheap plentiful commodities (16GB GDDR6 and a 1TB PCIe 4.0 SSD). now those commodities are killing the BoM.
Again, I don't know where you are getting this nonsense from? What bad performance per area? How are you arriving at that???? To say that with any degree of fact, then yu have to point out something that was made in 2020... hell, even 2021/2022/2023, that for the price or APU size of the PS5, could give you better performance.
And don't forget, AMD did not even have ML hardware at the time the PS5 came to market.
And what do you even mean cheap plentiful commodities? What does that mean... going with GDDR6 and 16GB was not them being cheap, or evn them being expensive, its what you need to have in a console that is supposed to be capable of doing 1080p-4K in the graphical envelope they operate in at 30-60fps. Thats the minimum you need to have "good enough". There is a reason why a switch 2 that released almost 5 years after the PS5, doesnt and cant even look as good as a base PS5. And that's because you are in two completely different worlds with the tech and design goals for that tech.
On one hand you are making a machine with an APU that can push 250W. On the other you are making something that should be able to do 25W.
Nintendo otoh went with a Nvidia Ampere+ SoC, which is much better than RDNA2, they then chose the cheapest process node imaginable for it. Thus Nvidia's superior technology made up for the process's shortcomings. That's how Switch2 is beating the daylight out of Steam Deck.
Do you have any idea how much an APU from Nvidia would have cost for Sony and MS for the kinda hardware they are trying to build? Do you realize that they can't switch from an x86 architecture to an ARM one without completely breaking backwards compatibility? Lol at Nvidia's superior technology, any technology is only as good as its ability to meet your needs. eg. The steam deck, has an X86 APU, because it wants games made for desktop PCs... to just work on it. And Nvidia doesn't make any low power APU that is X86. As I said, tech is only as good as what can meet your needs.
They then proceeded to use bottom bin garbage for commodities. (12GB LP5-6.4 + 256GB PCIe 2.0 class phone storage). Resisting game developer calls for more.
Ok... now do that for something that's supposed to be driving 4K IQ and fidelity on par with a PS5. Nintendo didn't do anything smart here... they simply just built a handheld. Nothing more, nothing less. If I were designing a handheld, I would have done the same thing.
And what's crazy is that you don't realize that's the same point you are making, albeit through rose-tinted glasses, but you are helping make the point that Nintendo just built a handheld.
