New Dual 1.42GHz G4 CPU Upgrades Announced by Giga Designs

The dual 1.42GHZ and 1.4GHz G4 CPUs will fit the original 2002 "Mirrored Drive Door" Power Mac G4s through those released subsequently in 2003 and cost $699 according to Giga Design's press release. The module uses a copper heat sink and a quieter fan than those in the original Power Mac G4s.

Check out our October 2003 Dual 1.42GHz G4 vs Dual 2GHz G5 Power Mac comparo for some idea of relative speed--the G4 did surprisingly well--and our original Dual 1.42 GHz speed test in July 2003 that compared it against a G4 Cube upgraded with a single 1.2 GHz G4 CPU.
