As I said earlier (and in different threads), in theory it doesn't have to be in dock, but in main unit.

For the sake of thought experiment, slap two Tegra X1 onto the same die, make it 14nm and run only one downclocked to 700MHz in hendheld mode for ~360 GFLOPS and (if my math is correct) around 10W TDP and run both @1GHz when docked for 1TFLOPs. Or slap 3 X1s for 1.5TFLOPs.

Of course, this is all just having fun with guesstimates, no idea what tech at what cost nVidia can provide, and what is Nintendo willing to pay.

you can't just 'glue' 2 processors together, that's not how it works. also having 2 processors would also increase the tdp (terrible on a handheld) and also lower the battery by a ton. all of this without even thinking about price, that would be a whole new can of worms.

the easiest way to think of it is, if it was possible to have around the x1 performance in a tablet, the x1s wouldn't have the size it does (even adding the optical drive).

regardless, for a handheld this should be plenty powerful, it should not be compared to a regular console as it wouldn't even be fair to what they are trying to do.

Actually you kinda can - and they do it. Read Eurogamer's interview with Mark Cerny on PS4 Pro - they've, more or less, just added mirror copy of PS4's GPU and built it on lower node, thus higher base clock. When PS4 Pro is in PS4 mode it simply disables half of GPU and downclocks itself.

Also, PowerVR GPUs...scalable almost like LEGOs.

Not that I said that's what nVidia would actually do with X1 successor (remember...I said "for the sake of thought experiment") - as I said, in "home" or "docked" mode full GPU is enabled and it's running at full clock. In handheld mode, half of it is disabled and it's downclocked - but it needs to deal with much lower resolution of handheld, so that's ok.

And again, this is just having fun with guesstimates, new console launches are always fun times for people who like to do such sort of thing.
