1. A graphics subsystem, comprising: a plurality of world-space pipelines, wherein each world-space pipeline is implemented in a different processing entity and processes one or more primitives; a plurality of bounding box units, wherein each bounding box unit is associated with a different world-space pipeline, receives the one or more primitives processed by the different world-space pipeline, computes a bounding box for each primitive included in the one or more primitives, and transmits the one or more primitives and one or more bounding boxes to a crossbar; a plurality of screen-space work distribution crossbar units that are coupled to a downstream side of the crossbar and receive the primitives and the bounding boxes from the crossbar; a plurality of tiling units, wherein each tiling unit is coupled to a downstream side of a different corresponding screen-space work distribution crossbar unit included in the plurality of screen-space work distribution crossbar units; a plurality of screen-space pipelines, wherein each screen-space pipeline is implemented in a different processing entity and is coupled to a downstream side of a different corresponding tiling unit included in the plurality of tiling units, wherein each tiling unit aggregates any primitives received from the screen-space work distribution crossbar unit corresponding to the tiling unit into one or more cache tile batches, and transmits the one or more cache tile batches to an upstream side of the screen-space pipeline corresponding to the tiling unit for further processing.
