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

[Solid-Stark]

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.
