What matters is how easy it is to create an out-of-order implementation of an ISA, there isn't a 680x0 equivalent of the Pentium Pro.

They produced variants up to 300mhz if I recall but then relegated it mostly just to microcontroller market and then stopped developing it. It was too late, and just oh-so-slightly incompatible with 680x0. But I suspect if the ISA used in ColdFire v4 had existed in 1994, 1995 that perhaps Apple's honestly disastrous foray through PowerPC could have been avoided.
