Different computers receive different updates - that update has to include the info for every model computer.
...At least I assume that accounts for the difference.

Hello,
I think the difference in the update sizes is related to
updating X11. If you do not have X11 installed the update
will not be the larger size.

Not sure if is the right answer but prior to 10.5.2 i did a complete erase & install when i opened the software updater my update showed up as 343mb so maybe this is a large bundled update including previous updates
