There's no real point in using other consoles with architecture's that are like 8-10 years older and from completely different companies (AMD).
You have as good of a direct comparable as you're going to get in the RTX 2050 laptop GPU. It is the same exact architecture as the Switch 2 with similar numbers of CUDA cores, it has 25% more CUDA cores, but it has less RAM (only 4GB), and even less bandwidth (20% less with 96GB/sec versus 120GB/sec for Switch 2).
That's why Digital Foundry did a whole video testing a downclocked RTX 2050 on various games, to simulate a Switch 2. That's going to give you the closest idea of what Switch 2 could do, 2050 has a bit more CUDA cores but it has worse RAM and worse bandwidth.
