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?

7nm fabs are up and running now, nVidia just needs to work with TSMC and bring the design over. (Not as simple as it sounds sadly.)

Yeah. Easy doubling in performance with lowered clocks+voltages+binning over the X1 at the same TDP.

On the bandwidth front, I would assume Nintendo would make a few cut backs there, Half of 137GB/s is still a respectable 68.5GB/s of bandwidth, which is still a substantial increase over the current Switch.
