I notice the difference even when typing. The performance improvement is most noticeable for me when editing large files in vim or having a lot of tmux panes open. Alacritty and other GPU accelerated terminals perform a lot better here and things just feel smoother.

There's an older HN thread [1] on the subject with benchmarks and lots of interesting chatter. It's worth a read IMHO.

You might want to try iTerm with gpu acceleration enabled. The only caveat is you lose some visual features, like transparency, but I found it well worth it.
