Reply to comment by ThatGenericName2 in ELI5: Why do computers need GPUs (integrated or external)? What information is the CPU sending to the GPU that it can't just send to a display? by WeirdGamerAidan

And before integrated GPUs or even discrete low-powered GPUs the User Interface was rendered using the CPU itself (software rendering). This was a long time ago, back in the old days of text interface in CGA and simple 2D sprites. (1980s)
