Power efficiency mostly. The power requirements of an exascale machine with 2010-timeframe hardware would be crazy.

  Oak Ridge still consumes 20 megawatts. However older technology was appearing to require a gigawatt.

    That really helps me appreciate the power efficiency gains! So much improvement in so short time...

      But unfortunately power efficiency of GPUs seems to be levelling off recently
