Re-reference aware tile walk order for primitive binner

A method to process tiles of a screen space includes determining a tile-processing order for tiles of a first batch of primitives based on a tile-processing order for a second batch of primitives in which the second batch of primitives are processed prior to the first batch of primitives. The tiles of the first batch of primitives are processed based on the tile-processing order determined for the tiles of the first batch of primitives. The tile-processing order is updated as tiles of the first batch of primitives are pushed to a backend processing portion of a graphics processing unit. In one embodiment, determining the tile-processing order for the tiles of the first batch of primitives include arranging the tiles of the first batch of primitives that have a same screen-space as tiles of the second batch of primitives based on a most-recently-processed-tile-to-a-least-recently-processed tile order of the second batch of primitives.
