   And the fact that all the RISC processors ran rings around the CISC ones.   
   So they wanted to promote that "hey, we can go fast too!"   
      
   Ok, AMD dropped the "risc" prefix 25 years ago.   
   That didn't change the way it works internally.   
      
   They still use the term "micro op" in the Intel and AMD Optimization guides.   
   It still means an micro-architecture specific internal simple, discrete   
   unit of execution, albeit a more complex one as transistor budgets allow.
