iMac vs. iMac


Having upgraded from the old "lamp-style" flat-panel iMac to a new G5 iMac has given me the chance to perform some benchmark tests, comparing one machine to the other. Here's the specs on the two machines:

G4 iMac: 700 mhz, 384 MB of RAM
G5 iMac 1600 mhz, 1.25 GB of RAM

Note: All tests of the G5 iMac are made with the processor settings set at "automatic" unless otherwise noted.

Note (Feb 6, 2005): Added a few specs from a G4 Powermac.
