Because that's what a 200 MHz PowerPC 603 gives you. Checking the BogoMIPS howto will show you one report of a 603, running at 100 MHz and giving 66 BogoMIPS, which is at par with our results. > I still think that the correct value is 400. Unless you have tried other 603-based sytems you have no reason to think so.
