It doesnt relate to framerates.
It relates to how much details textures can be on screen.
That was why the UE5 demo was impressive.
It showed hollywood movie quality assets, of scanned objects loaded, as 8k textures used on a massive scale.
"Does loading 16GB/s into the ram leave room for other tasks?"
Neither the Xbox SX or the PS5 will fully use that for games.
Nor is loading things into ram a static thing, esp now with the SSDs.
Thats the entire logic behinde the claims that the PS5 SSD is so fast, you dont need to keep nearly as much things loaded in the ram anymore.
You can simply load anything on the fly, when needed so fast, it can basically happend as your character is turning around (ei. things out of view, can be loaded in and out of memory, as you move the camra view of your character around).
Basically Ram pool size is more than doubled, and smart techniques and the speed of the SSD IO, will enable you to use ram much more effeciently than before.
So even if in actual terms its only perphaps "twice" as much (8gb->16gb) to developers, it will feel like its alot more than that.

so you get the same performance cost with 30fps as with 120fps?

SSDs are too slow to matter in the context of a single frame. The PS4, for example, can pull about 3 gigabytes in the timespan of a single frame (176 GB/s RAM compared to 5GB/s PS5 SSD). If you recall how during the PS1/PS2 days, the disc would not always be spinning, it's because only at certain points in the game does data need to be read from the disc (or HDD in PS4s case / SSD in PS5).
The SSD is not likely to make an impact when it comes to visuals. It can allow game assets that are stored in RAM that are no longer needed to be swapped out for assets at a much faster rate, but that's generally not a bottleneck, and the only times you would notice it is occasionally in open world games or some poorly optimized racing games when you are going too fast and the world pauses for a second to load in the surrounding area.
