Almost everything you said was wrong.
1) We don't know the memory bandwidth of the Switch 2. It hasn't been unveiled.
2) Steamdeck is 88GB/s, but also has a 102GB/s variant, it's ideal resolution is about 720P.
3) Legion Go is -not- 29.98GB/s of bandwidth. It's 120GB/s or there-abouts.
4) Rog Ally is -not- 25.6GB/s of bandwidth. It's 102.4GB/s.
Z1 Extreme supported memory/bandwidths:
DDR5-4800 DDR5-5600 LPDDR5-6400 LPDDR5X-7500 |
76.8 GB/s 89.6 GB/s 102.4 GB/s 120.0 GB/s |
The reason why the framerates drops when resolution increases is because they are fillrate limited, fillrate needs lots of bandwidth.
These devices are ideal for 720P/800P resolutions for modern titles that are pushing a ton of effects.
Remember the Playstation 4 had 8GB GDDR5 with 176GB/s of bandwidth and couldn't guarantee 1080P... And that console wasn't pushing Ray Tracing or other modern effects.

Teraflops is a useless metric and doesn't tell us anything about it's gaming performance.

TechPowerUP's GPU database is accurate up to a point... However it's only representing a 64bit memory bus, these devices aren't using a 64bit memory bus.
This is why it's important to have things in context.
Grabbing random numbers and running with it has always been an opportunity to get things wrong.
