Motivation energy is king

Motivation: Energy Is King

Performance = Power * Energy Efficiency

(Tasks / Second) (Joules/Second) (Tasks/Joule)

  • Power is fixed

  • For better performance, need better energy efficiency

  • Total energy is fixed

  • For “more” performance, need better energy efficiency
