An apparatus and method for adaptive spatial accelerated prefetching. For example, one embodiment of an apparatus comprises: execution circuitry to execute instructions and process data; a Level 2 (L2) cache to store at least a portion of the data; and a prefetcher to prefetch data from a memory subsystem to the L2 cache in anticipation of the data being needed by the execution unit to execute one or more of the instructions, the prefetcher comprising a buffer to store one or more prefetched memory pages or portions thereof, and signature data indicating detected patterns of access to the one or more prefetched memory pages; wherein the prefetcher is to prefetch one or more cache lines based on the signature data.
