Sites that like to have fancy scroll or background effects are generally awful if you don't have a graphics card. I browse on a Celeron J4105 or a Pentium Gold sometimes (I use it to build some x32 bins) and JS-heavy sites cause full tab lockups that take minutes to resolve until anything is usable at all.

Think of devices like this: https://www.bluproducts.com/devices/studio-x10-2022/ This is a 2022 model, with 1 GB ram. On a Samsung Galaxy A03 if I swap between tabs in browser, HN will appear near instantly, I assume because it hasn't been evicted from memory, but anything heavier will take a few seconds and be a full page reload.
