Techniques and mechanisms for tile prefetching to be performed based on both intra-tile stride characteristics and inter-tile stride characteristics. In an embodiment, a prefetch circuit of a processor core detects that multiple demand fetch instructions target different respective tiles of a matrix. Based on the multiple demand fetch instructions, fetch pattern information is registered and made available for future reference to facilitate detection of a later instance of the fetch pattern. Fetch pattern information corresponding to a first demand fetch instruction comprises both an inter-tile stride and an inter-tile stride. In another embodiment, the prefetch circuit generates micro-operations, based on the fetch pattern information, to prefetch one or more tiles of the matrix.
