a G-what is inside?

If you ever wondered what CPU is ticking inside your Mac the [PowerPC overview][1] may help. My “Apple -> About This Mac” says that I have a

PowerPC G4 (1.1)

CPU-Geschwindigkeit: 1.33 GHz

L2-Cache (pro CPU): 512 KB

Speicher: 768 MB

Busgeschwindigkeit: 167 MHz

Boot-ROM-Version: 4.8.3f1

Seriennummer: 4H445LC8PLW

Actually I can’t match that to anything on the overview page, but anyhow…

PS: maybe it is a 74577460?!
