As for the resurgence of X2 / Pascal rumors, that's about the upper limit of what I could ask for from a portable system, which makes me suspicious since Tegra X1 sounds much more Nintendo's style of tempered expectations. A newer chip would make more sense though from a power efficiency standpoint, but then wouldn't that increase price? Maybe a Tegra X1.5 is more likely than a full X2.
Going back to the SemiAccurate rumor from May and how it relates to these new rumors, the entire reason Nintendo chose Tegra is because Nvidia's offer to Nintendo was a steal. Margins on gaming platforms apparently aren't great, but that isn't the value of it which Nvidia learned the hard way after getting ditched by Sony and Microsoft. First, it makes the company look worse than AMD if it loses contracts to the competition. Second, Nvidia presumably wanted a product that it can regularly showcase to other companies what its technology can do. That's what its own Shield product was supposed to do except nobody cared/bought it.
The thinking behind the original SemiAccurate rumor is the Tegra division was basically told, "Figure it out or go home," so Nvidia's plan was to sell Nintendo on Tegra. Nintendo isn't the end goal here though I wouldn't be surprised if part of this rumored deal is Nvidia insisted on a "Powered by Nvidia's Tegra" or something of the sort on packaging and actual unit. If margins on gaming devices are minimal, why bother? You do it for brand visibility, to increase the value of the product, and ultimately to reach out to other companies with products that will have greater margins.
What this means for Nintendo is it'd get a great deal on a pretty advanced technology which is just about the only way Nintendo would do such a thing.
Just being honest here guys, Tegra X1 and X2 would need to be extremely downgraded to have any good battery life. Wii U portable? Meh
X1, yes. X2, no. The entire point of going with X2 is Nintendo would get better performance than the best X1 with greater efficiency. X1 is about twice as powerful as Wii U. X2 with decent battery life is expected to be in that range.
About bringing Third Party games to NX: "one that's easy to program and work on" no Third Party would port to Tegra
Porting to Tegra isn't that difficult. Just about all middleware supports ARM.
That may be but amd had socs Nvidia does not, this is reason to believe it'll be amd for the home console.
Maybe I'm misunderstanding you, but Tegra is a system on a chip. If you're talking about contracts again, it's conceivable that Nintendo asked Nvidia not to announce anything as it would out NX immediately. If Nvidia were to announce a semi-custom design wins as AMD had, everyone would know it was Nintendo as both Sony and Microsoft very publicly jilted Nvidia.
I'm not really sure why you're so vehemently against Nintendo going with Nvidia's Tegra. I've been #TeamAMD for years now, but in light of everything above, it makes sense. If Nvidia offered Nintendo a deal that AMD couldn't match financially and/or technologically, I don't see why Nintendo would ever not take that deal.
