Even low-end GPUs like Intel's integrated ones or Mali GPUs on ARM can use OpenGL well these days. The latest releases of Mozilla Firefox include a GPU-based rendering engine which works very well with my integrated Intel UHD 630 on a 4K monitor in full screen. If Firefox can do that (with its multitude of supported graphical elements, animations and effects), Emacs certainly can do it too.
