    Today's modern CPUs put out less heat per cycle and exhibit less heat   
   per "MHz" of "operating speed".   
      
     The Athlon family and the Cell are perfect examples of more work done   
   with less heat than a 66MHz Pentium, so I am quite sure that they are   
   using more advanced CPUs than that.   
      
     Link budget is what matters, and is the main argument for wanting a new   
   constellation of military networking satellites.   
      
     I think eventually, they will put up a new string, but right now, we   
   have bigger (slower) fish to fry, and our frying pans are doing just   
   fine, albeit showing signs of being taxed.
