This is for sure the case for vendor solutions, but AOSP itself is still quite the lean OS. Android also has GO variants which perform even better at low resources, (Bliss also has builds of these if one is curious). They are extremely responsive. I don’t think Bliss as A14 go builds, but we do have A13 go builds, and they are extremely responsive on very low end hardware, the bar is actually support for SSE.
Bliss currently has a hard requirement on SSE 4.2 or greater due to a load of changes (occasionally some work is made on lowering this but it’s slow and a lack of real motivation), but pretty much everything I have tested that is supported works fairly well, from my old i3 desktops, my atoms and celerons etc.
at least if the memes were good. It’s just bad man this bad man that or dementia man dementia man that.
