Systems and methods for pipelined synchronization in a write-combining cache are described herein. An embodiment to transmit data to a memory to enable pipelined synchronization of a cache includes obtaining a plurality of synchronization events for transactions with said memory, calculating one or more matches between said events and said data stored in one or more cache-lines of said cache, storing event time stamps of events associated with said matches, generating one or more priority values based on said event time stamps, concurrently transmitting said data to said memory based on said priority values.
