Actually those mip ratings are very misleading.  sure, a RISC processor will
get more mips, but then it will take more clock cycles to do a complex
instruction than the current 040, because there is a smaller base set of
instructions to work on.  in it's best form (i'm assuming simple block moves)
a RISC chip blows the pants off a CISC, but when you get down to real
processing, the effective mips drops.
