Don't know why people jack off about this nonesense.. Really think Nintendo is going to stick a 1660m in a switch without a $800 price tag?
There's a silicon sshortage, the success of the switch originally was the use of a mass production chip that made mass production easy, and that's more important than ever this time.

Don't know why people haven't noticed this but they made a dev kit suffix with "NX" (the switch codename)separate from the other TX models.
The "Jetson tx1 NX" has the exact gpu, mem, and cpu, with added Denver which they probs deactivated.
The only other NX model they've made is the Xavier NX, which is a 384 core vollta chip with 48 tensor cores. 8gb with double the bandwidth.
It's possible that they've got a sneaky one on the way, but given the previous NX model was bang on, this makes perfect sense, it's powerful enough to run 1080 and had ai for up scaling (because only an idiot would a totally believe they'd pull 4k rendering when the ps4 pro used 1440p)
As I said, this would also alleviate the issues with supply as the XNX board has already been mass produced for cars and would enable them to drop the pro at a far more accessible price point.
A 2048 core switch.... Seriously kids....
