G4 (dual 1.0 and 1.25 Gz) and 1.6 Ghz G5 Xbench 1.1 Comparison

The data below represents Xbench 1.1 results from my two PowerMacs, a 2001 dual 1 Ghz G4 Quicksilver and a 2003 dual 1.25 Ghz G4 MDD compared against a 1.6 Ghz G5. The G5 results were pulled from the Xbench Comparison site, and I used this particular set of data since it was consistent (same result from two runs) and seemed fairly representative. I hope to add some 1.8 G5 data to this set shortly. Hard disk test results are not included.
