And to all of you fellow nerds back there who also like to know how things work and why - bless your heart. Actually, I don't fully follow the explanations, but clearly the 603 core is not able to execute a single looped dbnz once per clock, so 263 BogoMIPS is a reasonable number for a 396MHz 5200. The number does not have anything to do with bus speed, which is part of what was bothering me (2 x 132MHz, you know). I won't pester you all with this any more but if anybody else wants to discuss further I'd welcome your emails (not discuss BogoMIPS necessarily, but details of 5200 performance - I've got some very challenging requirements to hit and any insights will be welcome).
