Actually Mojo is not a very good benchmark because it contains Intel and PC optimized code. There is no counterpart of alti-vec optimized code for the G4 in mojoworld. I know the lead programmer and he knows how to get every ounce of horsepower out of the PC. The Mac version is a port to something like xwindows (not written by him) and it is rather crippled. If a direct version were written for the Mac it might be a fair comparison. You might want to stop cackling now.
