Oddly enough I benched an ATI Rage 128 yesterday when I was getting my old G3 Processor based iBook (the clamshell model with the built in handle) ready for donation to a local charity.
I ran a few loops of Cinebench 2003 on it as it runs an out dated PowerPC based version of OS X (10.3.9 for those wondering) and can't use Windows or 3DMark.
The Rage 128 Mobile scored 18 on the OpenGL hardware test, just for comparrisons sake an AMD HD 5770 scored 8773. That's almost 500 times faster performance done by a mainstream card that's 18 months old.
As for the CPU the G3 433 Mhz scored a 215 while my first gen i7 sig rig at 4.0 Ghz scored 22154, that is only 103 times faster
