Granted, I am giving time odds to the clones, and I did not play a >large enough number of games. Does the 3X factor sound correct? Why don't you just set up the starting position, put Genius 5 in the analysis mode, and count the number of nodes for say 5 minutes. Then do likewise on the other machine. This should give you another, and I think better, comparison of the speed ratio of Genius 5 on the two machines.
