EDIT

Apparently this video is 3 months old.

I am glad that Nintendo choose NVidia with the Switch. They are the leading business when it comes to graphic technology.

Tegra Xavier (Volta) based Switch in 2020 or so is the next step I think (in terms of a significant hardware revision, not just die shrinks). 

The way they could ensure compatibility is the could make the current docked mode the new undocked mode. So the "new" Switch could run at 450 GFLOPS undocked (1 TFLOP docked).

For people with older Switch units, Nintendo could make a battery pack add-on for certain advanced games, so that they'd be able to run at 450 GFLOP mode for 3 hours even portably. Really the reason the Switch can run full clock in portable mode is because the battery would die too quick, but that could be alleviated if Nintendo made an official "portable battery dock" for the original Switch. Battery packs are cheap. But the 1 TFLOP performance mode would be just for the new Switch.

So? They've been a pretty poor console business partner in the past and since most people in "the industry" use OpenCL anyway, it makes no difference whatsoever.

There is more than just "moar flops" going into Volta.

Nintendo could have used a more energy efficient display, used a higher capacity battery using a different chemistry, have the chip fabbed at 14/16nm FF, cut some of the faster CPU cores off which would have increased battery life and allowed for an increase in performance. - But they decided to cut costs in those areas.

And price!

This video is months old.
Would have been nice if you did a short write-up as well.

Lol, I didn't noticed at all.

Generally speaking though if they can get something that is 2.5x the current Switch in a couple of years ... they likely stand to have a flood of developers wanting to bring PS4/XB1 content to the platform. 14nm/16nm is likely coming too, they probably got a helluva deal to use 20nm Tegra chips for a set number of units, once they are clear of that they can move on to die shrinks if they wish I would imagine. 

Maybe they will use a more energy efficient display in future models, my feeling Nintendo's future is going to be Switch models at different pricing tiers, so $299.99 as a pricing tier will remain, just with new hardware cycled in at better specs, while older models move down the chain in the lower cost categorey, especially when the 3DS is completely gone. 

You have to think goal oriented, not input oriented. What could be the purpose of a new chip? 4K gaming is not in reach so no bueno. The 720p display is small so more powerful graphics add nearly nothing for the end consumer for mobile gaming. The only realistic option right now is energy saving for the few that use a Switch long term outside.

The possible advantages of a new chip would be.

Better battery life, higher resolution (for games that are sub 720p/1080p), higher/more consistent framerate, other graphical improvements, lower load times, more responive OS.

But really the main reason they won't be sticking with the X1 for the next 5+ years is it'll eventually be cheaper and more practical to use newer chips anyway.

Why not a SLI dock?
