So the newest "leak" (from Famiboards) seems to be a 560 Mhz handheld clock known from data-mining. Not bad, not bad, if true. Should probably allow it to run games similar to Steam Deck graphics quality settings, but with DLSS & more memory bandwidth it would be capable of reaching slightly higher effective image quality.
And again, the Switch 2 would be able to do this at lower power-levels because it takes a wide (many core) and slow (low clock-rate) architecture, which is more power-efficient than the Steam Deck's few-core, high clock-rate repurposed APU. That and the fact that it doesn't need to depend on a compatibility layer, and it has an ARM chip.
Assuming the docked mode is about 1.66 times the handheld clock-rate (akin to the original Switch's 768Mhz vs. 460Mhz) we're looking at a 896Mhz dock mode. For those of you interested in the TFLOPs that is about 1.72 TFlops in handheld, and 2.75 TFlops in docked mode. (See Edit) Probably would put the Switch 2 (docked) at roughly half the Series S in terms of raw raster-capability given how RDNA2 and Ampere compare, flop for flop. Closer to the Series S when talking about ray-tracing/raster mixed workloads.
EDIT:
Same leaker is saying 1007.3 Mhz for Docked mode. So 3.1 TFlops. 54% of Series S "raw rasterization" assuming Ampere vs. RDNA2 relative raster-unit/TFLOP.
