    摘要: Methods and apparatus to optimize package level power state usage are described. In one embodiment, a processor control logic receives a request to enter a lower power consumption state (such as a package level deeper sleep state). The control logic determines the time difference or delta between a last entry into the lower power consumption state and the current time. The control logic then causes the flushing of a last level cache based on a comparison of the time difference and a threshold value corresponding to the lower power consumption state. Other embodiments are also claimed and disclosed.

    摘要: Techniques are disclosed involving techniques that may dynamically adjust processor (e.g., CPU) performance. For instance, an apparatus includes a counter, an efficiency determination module, and a management module. The counter determines a number of event occurrences, wherein each of the event occurrences involves a processor component (e.g., a processor core) awaiting a response from a device. The efficiency determination module determines an efficiency metric based on the number of event occurrences. The management module establishes one or more operational characteristics for the processor component that correspond to the efficiency metric. Other embodiments are described and claimed.
