Here is my final prediction:
If GPU is Tegra T239:
The performance level to expect when docked (assuming 18-20W total power target) would be about 85%-90% (in terms of framerate) of a RTX 2050 mobile 25W.

The performance level to expect when portable would be slightly better than the base PS4, but of course with more modern features (i.e ray-tracing.)
Over time the Switch 2 would outperform the 2050 mobile because it would have much more video memory available.
As far as desktop GPU's are concerned, it would be somewhere between a GTX 1050ti and GTX 1650.
IF GPU is a Lovelace Tegra or if power target of the T239-based platform is loosened to 25W-30W total:
The performance level to expect when docked (25W-30W power target) would be somewhere between an RTX 2050 mobile 25W and RTX 3050 mobile 35W 4GB, likely closer to the latter.

A roughly comparable desktop GPU would be the RX 570 or a GTX 1650.
This would put it at about (or very slightly below) the level of a Series S when docked, with the Series S more like a GTX 1650 super/GTX 1060/RX 580.
When portable, I'd expect between PS4 and PS4 Pro performance.
EDIT: DLSS isn't magic, but it can in many cases bridge the gap between a budget/performance half-tier or even tier (i.e GTX 1650 level -> GTX 1650S level; RX 570 level -> RX 580 level; GTX 1050ti level -> GTX 1650 level, etc.) Half-tiers/tiers tend to be about 5%-15% more performance than the iteration they improve upon. That's in the realm of what gains the Switch 2 would expect to get for using DLSS over FSR and slightly decreasing internal resolution (say internal 800p instead of internal 900p/1080p by using DLSS rather than FSR; 30%-50% reduction in internal pixel-count for similar image-quality target.)
EDIT 2: I'd expect most Switch 2 games to upscale from 720p-900p -> 1080p or 1440p in docked mode and from 540p-720p -> 720p-1080p in handheld mode (depending on the screen resolution mostly.) Some simple 2d/2.5d titles would do 1080p -> 1800p or 4k. VRR would be nice, but if there isn't VRR then we'll probably have a 60fps target for simpler games, and 30fps for graphically demanding ones, dependent on genre too of course.
