I think the rumor is false because I still think the Switch 2's next chip may already be shipping in the new Jetson Orin Nano embedded PC, which coincidentally went on sale today and got its first preview at TomsHardware:

It's designed to replace the previous Jetson Nano devkit which uses the same Tegra X1 that went into the Switch.

Even if the GPU only works at 625MHz, it should still be an enormous upgrade over the Switch, and it might be close to the Steam Deck in performance.
