   That is then plainly wrong.

   It may be run as fast as a 68040 clocked at 120MHz, bit it *is not clocked*   
   internally at 120MHz - that's the thing about being superscalar.   
      
   There is an important difference: a superscalar CPU will only get that   
   performance some of the time - it is not always 2* speed, it depends on the   
   mix of instructions - only some can be dispatched to the second execution   
   pipeline.

   This *is* the documentation for the real hardware - you won't get it any   
   more exact than from the manufacturer of the CPU.
