Now after installing #MacOS9 on an #Apple #iBook G3 600MHz I did some benchmark against my #MacMiniG4 also running MacOS9 (via the ROM hacked image).

The #PowerPC G3 in this iBook surprisingly slow. I expected half of CPU performance, of the G4 not less than a third compared to the 1.2GHz #PPC G4 in the Mini. And it's rather close with the built in reference result of a #Powermac G3 300MHz.

The FPU benchmark looks better though...
