Abstract: Systems, apparatuses and methods may provide for a smart power manager that dynamically activates or deactivates the individual lanes of each link of a router based on the allocated power limit and the connected applications. The smart power manager may optimize the router throughput for a given power limit dictated by a global power manager, and use a fine grained credit mechanism to track active lanes. The router power manager may also adjust the number of active lanes for each link individually so that highly utilized links will have more active lanes than links that are idle.

The data may be collected continuously, and may be used to alter the frequency, speed or other operating characteristic of the cores as well as groups of cores.
