A method and system for determining an energy-efficient operating point of the platform or system. The platform has logic to dynamically manage setting(s) of the processing cores and/or platform components in the platform to achieve maximum system energy efficiency. By using the characteristics of the workload and/or platform to determine the optimum settings of the platform, the logic of the platform facilitates performance guarantees of the platform while minimizing the energy consumption of the processor core and/or platform. The logic of the platform identifies opportunities to run the processing cores at higher performance levels which decreases the execution time of the workload and transitions the platform to a low-power system idle state after the completion of the execution of the workload. Since the execution time of the workload is reduced, the platform spends more time in the low-power system idle state and therefore the overall system energy consumption is reduced.
