   I was having a chat yesterday with a man who was fairly involved with   
   ACORN and ARM back in the day. He put it very simply:   
      
   For a given clock speed, which is limited by the physical dimensions of   
   the chip, the smaller the transistors the less power it takes to run the   
   chips.   
      
   However fabrication limits are getting stuck at 10nm and below,  and   
   clock speeds are stuck at a few GHz which means that the   
   power-performance ratio is pretty much the same for Intel and ARM   
   architectures. Only by having fewer transistors and implicitly doing   
   less, can the power be reduced.   
      
   I.e. Moore's law has basically stopped representing reality. And ARM is   
   no longer fantastic power performance compared with Intel. Its one   
   advantage is it doesn't have to support a legacy architecture. And so   
   its probably cheaper and less buggy.   
      
   So the price performance is probably still there, but not power.
