    1. Opening up the POWER architecture

    2. Power Systems

    3. So what??

  • 2015 IBM Corporation

    Moore's Law meets the law of physics

    Moore's law is the observation that, over the history of computing hardware, the number of transistors in a dense integrated circuit doubles approximately every two years.


  • 2015 IBM Corporation

    For almost 5 decades we have relied on exponential technology change
