   The notion that some paths are critical (and those determine the   
   frequency that can be used) implies that there are paths which are not   
   critical, because they're much shorter, e.g. the low-bits of an addition   
   don't need to wait for the carry-propagation, so they're typically ready   
   long before the end of the cycle.   
      
   Do CPUs try and save power by making those paths slower (using lower   
   voltage, or slower and less power-hungry transistors)?
