Summary:An apparatus and method for managing a frequency of a computer processor. The apparatus includes a power control unit (PCU) to manage power in a computer processor. The PCU includes a data collection module to obtain transaction rate data from a plurality of communication ports in the computer processor and a frequency control logic module coupled to the data collection module, the frequency control logic to calculate a minimum processor interconnect frequency for the plurality of communication ports to handle traffic without significant added latency and to override the processor interconnect frequency to meet the calculated minimum processor interconnect frequency.
