Interesting conversation, rumor / speculation over on NeoGAF about the Tegra SoC for Switch.
Some of that posted below.
Before I post it though, keep the following in mind regarding Nvidia's names for different generations of Tegra processors, to help avoid confusion!
"Kal-El" - Tegra 3
"Wayne" - Tegra 4
"Logan" - Tegra K1 (Nvidia Kepler architecture)
"Erista" - Tegra X1 (Nvidia Maxwell architecture)
"Parker" - Tegra ?? (Nvidia Pascal architecture) Not officially Tegra X2 but everyone calls it X2.
"Xavier" - next gen Tegra SoC. (will use Nvidia's Volta architecture). Nvidia won't even start sampling this chip until late 2017, therefore Xavier obviously won't show up in products until sometime in 2018, most likely.
With that out of the way, here's that NeoGAF conversation:

The following information comes from Teut Weidemann, one of the first German professional game developers. He worked at Rainbow Arts, Microsoft USA, cdv Software Entertainment, Ubisoft and more. It does not seem that Mr. Weidemann is working on the Switch himself, but he is in contact with devs that have dev kits.
* Switch screen is a touchscreen that supports up to 10 points of interaction
* current dev kits are running on older hardware specs
* Switch may be based on the new Tegra X2, which is quite a jump from the X1
[strong]Cool, another source suggesting Pascal. And I'm gonna assume when he says Tegra X2 he means Parker.[/strong] Going from a base Parker chip, what are the likeliest modifications we're going to see? I've read before that Denver cores have no business being on a console, so I imagine they'd go.
Another source calling it X2, however, I can understand why they would. The Tegra Parker was made for auto-driving cars, ergo it's name (IT'S A CAR PUN!). So calling it X2 makes more sense, but it's probably the exact same thing as the Parker, albeit with custom assets for the Switch (more focus on GPU than CPU functions maybe?).
[strong]It's actually named Parker after Peter Parker. The X1 was Erista (Wolverine) and the next one will be called Xavier.[/strong]
Nvidia have been using superhero codenames since Tegra 3/Kal-El.
"Worst" case scenario is it X1 as base with heavy customization, maybe that's why some devs are saying it's probably closer to X2, which wouldn't be a surprise since Nintendo went all out including active cooling, something I never thought they'd include.
he main issue with X1 is that it uses the 20nm fab process which is pretty much obsolete with everybody skipping it and go for 16nm.
Parker itself (the current official name for X2) gets 750GFlops in FP32, 1.5TFlops in FP16. It's unknown exactly how much game code can be FP16 (and it would vary wildly game to game), but speculation puts us at somewhere between 20%-50% being possible in FP16. I don't think that translates exactly to up to 1.12TFlops, but it should perform a decent amount better than the 750 number indicates.
Nice so we could be looking at something quite close to XB1 which is 1.3TF right?
In pure flops? No, that would be unlikely. It's possible in this type of form factor but it's likely too expensive for what Nintendo wants to charge.
But Nvidia typically has better tools and software that end up getting better performance out of their hardware, at least on PC (which is apparently where we get the whole "Nvidia flops are better than AMD flops). We don't know if that will be the case on a console though.
So we really don't know what the real world performance will be, but it's likely much closer to XB1 than Wii U.
I think it will be fully custom and probably better than parker to be honest. With some of the things they learned building Xavier.
