a G-what is inside?

If you ever wondered what CPU is ticking inside your Mac the PowerPC overview 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 7457/7460?!
