Abstract: In one embodiment, a processor includes: a first cache controller to control a first cache memory. This cache controller may include a replacement circuit to: associate a first priority indicator with a first cache line based on storage of demand data in the first cache line and first learning information associated with a set of demand-based categories of cache lines; and associate a second priority indicator with a second cache line based on storage of prefetch data in the second cache line and second learning information associated with a set of prefetch-based categories of cache lines. Other embodiments are described and claimed.
