As the procs are CMOS, power consumption would be a linear function of processor frequency, for a given device geometry. As device geometry was shrunk, so also was power consumption. > And these figures – I'm guessing – are only for the processor, not the > complete > processor module. The cache would add a tad to the total power consumption. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
