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.

The thing is though, if they make Switch 2 backwards compatible, they lose their chance to rip off consumers by making every second Switch 2 release just a rehashed full-price Switch 1 game at a higher res. I can see them axing back compat for this reason alone.

Not true, Wii had backwards compatibility with Gamecube and it still had Metroid Prime 1 &  2, Pikmin 1 & 2, Donkey Kong Jungle Beat and Mario Power Tennis ported to it.

Guess there really is no way to check greed and laziness.

As long as consumers show they are willing to buy them than there is nothing greedy or lazy about it, they are literally giving the people what they want.

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.

It's still lazy to just re-release last gen's games instead of making new content and it's still greedy to charge full price for them. Most consumers are just too stupid to know when they're being ripped off.

Is it lazy to rerelease old movies onto Blu-Ray for full price with no new content instead of making brand new movies?

Also, it's not instead of, it's in addition to. Nintendo porting Mario Kart 8 to Switch allowed that team to make a new IP in ARMS, porting NSMBU allowed that team to make Mario Maker 2

Same goes for other publishers. Porting old entries in Mega Man, Resident Evil, Street Fighter, etc did not prevent Capcom from releasing games like Monster Hunter World, Resident Evil 7, Devil May Cry, etc.

Releasing previous gen games on a current platform let's people replay games they enjoy or play games that they are interested in but never had the chance to play.
