Remember how fast CPU's shot up during that time period, even on the Mac
side of things.  Memory increases had a lot to do with it as well.  7.5 is
where TCP/IP really started getting used, so that might effect it as well. 
The OS changed significantly during these releases.

My first Mac was a PowerBook 520c, it shipped with 7.1 installed, and images
of 7.5.x on the HD.  With only 4MB RAM base, you didn't want to run 7.5,
with 20MB RAM, it ran OK.  IIRC, my PowerMac 8500/180 that I got a year
later shipped with some version of 7.5 as well.

Additionally, I can't even imagine running these OS's with that little RAM.
