Isn't Tegra Xavier designed for cars though, not for mobile devices?
From what I've read the thing sucks 30 watts, far too much for a portable system.

Yeah it is. But the same held true to the Tegra X1 (Tegra Drive CX/PX) and X2 (Tegra Drive PX2).
Tegra can scale upwards and downwards fairly well in power consumption... Tegra X1 and Tegra X2 were 20w parts in the "drive' configuration, where-as Xavier is 30w... And Tegra X1 was still forced to scale downwards for the Switch anyway.
But... In saying that, it is a massive chip, so it would likely benefit from being fabbed at 7nm which will solve the bulk of issues anyway... But the real benefit would be the big uptick in bandwidth plus a more modern and efficient GPU architecture.

I see, thanks. So when is 7nm fab expected to be up and running?
And if Xavier is a 50% increase over the X2 in power and X2 is 50% stronger than the X1, would we be talking about 2.25 times the performance of the X1 in a mobile configuration? And would the claimed 127GB/s of bandwidth be viable in a mobile version, or would that have to be dialled back?
