Looking At Tegra Xavier -- The Next-Gen Switch Chip

What would be the clock speeds? This would allow us to make a lot more sense of this. I saw it asked earlier but it didn't get answered. OP implies some insane clock speeds.

The PX2 has two Tegra X2s and a GPU. The Tegra X2 is capable of outputting 750GFLOPS (0.75TF) at max reference clock speed of 1465MHz with 15W TDP. Two Tegra X2s at that frequency would be 1.5TF. If the PX2 uses these clocks then this makes up part of it's overall.

Now the Tegra X3 is set to have 512 CUDA cores. To have a PS4s similar GFLOP count then it would need to clock at 1800MHz. I'm pretty sure we'd be close to the thermal headroom of a portable case.

Xavier supposedly matches the processing power of the Drive PX2 (80 watts) but can do it at 20 watts. According to Nvidia anyway. That Volta architecture must be pretty amazing. 

I don't think Nintendo would even need a full Xavier, a Xavier with half the CUDA cores for example would likely still give you PS4 tier performance in a portable device at about 10 watts, which is less than what the current Switch consumes in docked mode (15 watts).
