For most users, a fast single processor should be sufficient. Even then, not every Photoshop function uses dual processors as you can see by our "SP" test. Spending extra for dual processors makes sense if you are running multi-processor aware applications like Photoshop (see "MP" test above). Therefore, the meaningfulness of the comparison will remain questionable.Ģ. Plus, the G5 Power Mac can be expanded to either 4GB or 8GB of memory, depending on the model. The reality is that G5 systems have a much faster frontside bus, memory bus, and graphics slot. Until you can put a G4 CPU in a motherboard with the same frontside bus speed and same memory bus speed as the G5, we can't really say whether a G4 running at the same clock speed can match it.

Though the 2.0GHz G4 upgrade produced respectable performance, it's no match for a dual G5 Power Mac running at the same clock speed.
