It's quite useful for things like skia or piet-gpu/vello or the general category of "things that use the GPU that aren't games" (image/video editors, effects pipelines, compute, etc etc etc)

would it also apply to stuff like the Switch, and relatively high-end "mobile" gaming in general? (I'm not sure what those chips actually look like tho)

there are also some arm laptops that just run Qualcomm chips, the same as some phones (tablets with a keyboard, basically, but a bit more "PC"-like due to running Windows).

AFAICT the fusion seems likely to be an accurate prediction.

    Switch has its own API. The GPU also doesn't have limitations you'd associate with "mobile". In terms of architecture, it's a full desktop GPU with desktop-class features.

      well, it's a desktop GPU with desktop-class features from 2014 which makes it quite outdated relative to current mobile GPUs. The just released Switch 2 uses an Ampere-based GPU, which means it's desktop-class for 2020 (RTX 3xxx series), which is nothing to scoff about but "desktop-class features" is a rapidly moving target and the Switch ends up being a lot closer to mobile than it does to desktop since it's always launching with ~2 generations old GPUs.

Those already have their own abstraction API, and implementing a RHI isn't a big issue as FOSS circles make it to be.
