The Power Mac G4 has shipped in several different configurations. The "Yikes!" model has a 100 MHz bus and takes the same ZIF upgrades as the Power Mac G3. The "Sawtooth" models have a 100 MHz bus, the 2001 and most later models use a 133 MHz bus, and the current 1.0 and 1.25 GHz dual processors machines have a 167 MHz bus. This page covers upgrades for Power Macs with AGP video and a 100 or 133 MHz system bus.
Moving to a faster CPU is as easy as removing the current one and inserting a new one in the zero insertion force (ZIF) socket.
Benchmark scores are supplied by the manufacturer.
The information is as accurate as I can find, but specifications and availability are subject to change; I suggest you check with the manufacturer to verify current models. Prices keep dropping, so these prices may be outdated. (Prices are in $US.) In fact, models are added and discontinued so often, it's impossible to keep track of which models are current.
Discontinued accelerators will be retained for historical reasons. Accelerators may not work in all G4s with AGP, particularly the Cube. Be sure to check manufacturer's site for full compatiblity data.
