摘要
Examples include a processor including a coherency mode indicating one of a directory-based cache coherence protocol and a snoop-based cache coherency protocol, and a caching agent to monitor a bandwidth of reading from and/or writing data to a memory coupled to the processor, to set the coherency mode to the snoop-based cache coherency protocol when the bandwidth exceeds a threshold, and to set the coherency mode to the directory-based cache coherency protocol when the bandwidth does not exceed the threshold.
