I bet it's difficult to normalize because performance depends on so many things. CPU cycles, but also other factors like RAM speed, swap usage, CPU cache sizes and speeds, background tasks, GPU and GPU drivers, OS, display servers (X11 vs Wayland on Linux), window managers, available fonts, and probably a ton of other things are other factors that will play a role.
