While one core is inactive, this feature allows one of the processor cores to temporarily operate at a higher frequency point than HFM when the operating system requests increased performance. This higher frequency is called the opportunistic frequency and the HFM frequency is called the guaranteed frequency. The opportunistic frequency has a bus ratio of (N+1):1, where N is the guaranteed frequency bus ratio.
