Abstract A method and system for managing bandwidth demand for a variable bandwidth processing element in a portable computing device ("PCD") includes monitoring bandwidth requests of a plurality of constant bandwidth processing elements and monitoring bandwidth requests of a variable bandwidth processing element. The variable bandwidth processing element may be either a graphics processing unit (GPU) or a central processing unit (CPU). The method may include determining if the variable bandwidth processing element needs adjustment to its bandwidth for a bus. Next, a message may be communicated to an aggregate bus driver indicating a level of adjustment for the variable bandwidth processing element. Based on the minimum frequency set for the entire PCD and the level of adjustment for the variable bandwidth processing element, the aggregate bus driver may set a new bandwidth value for the predetermined threshold of the bandwidth limiter for the variable bandwidth processing element.
