The first thing I notice when having he machines side by side is the HD on the G5 seems to be louder than the G4 .. it’s not a bad noise .. it’s more of a SCSI HD type of sound .. quite pleasant actually,, especially i your an old timer like me who always loved SCSI drives 😀

The G4 is faster to boot ?, but the G5 is quicker to shutdown .. hehe

Some o the little things I noticed was things like extracting a large (15mb) file with stuffit,, it was over 2x faster on the G5, I will let the bench tests below speak for themselves.

I am no professional tester, I just setup the machines on a identical boot, with no programs running in the background.

On next page I tested XBENCH .. some tests do show the Ti4600 is a superios card to the 9600 .. I will redo the tests once I get a better card, I also noticed some discrepancies (like FSB speed) on XBENCH that made me wonder if it’s at all optimized to run on the G5.
