I may have found a large difference between old and new 1.8 GHz G5s other than the PCI, RAM, and Hard Drive. I was looking around the xbench results page to try to decide what my next computer should be when I found something very strange about Dual 1.8 GHz G5s. It was that sevral of them scored 138 - 142 on the processor test while many others scored 174 - 175. I found it very strange that there would be a large group of them testing so low and another group testing so much higher so I decided to compare the specs of the processor and for the most part the 174 - 175 ones read: "Model - PowerMac7,3 Processor - PowerPC G5x2 @ 1.80 GHz" And the 138 - 142: "Model - PowerMac7,2 Processor - PowerPC 970x2 @ 1.80 GHz" This was not always completely true but was a tendancy Have a look for yourself here Could this be because of the new 970fx or maybe because of the new set-up of the Dual 1.8? Anyway I figured someone here knows what is going on. P.S. I did a search and found nothing like this.
