Systems and methods for improving cache efficiency and utilization are disclosed. In one embodiment, a graphics processor comprises processing resources to perform graphics operations and a cache controller of a cache coupled to the processing resources. The cache controller is configured to, in response to an instruction executed by one of the processing resources, modify an aging policy by modifying, based on the instruction, a level of importance from a first level of importance to preserve data longer in the cache for a first time period to a second level of importance for data to be evicted from the cache within a second time period, which is less than the first time period.
