A method and system for deferred coverage mask generation in a raster stage of a graphics processor. The method includes receiving a graphics primitive for rasterization in a raster stage of a graphics processor and performing a bounding box test on the graphics primitive to define a bounding rectangle for the graphics primitive. A combined coverage mask is then generated after the completion of the bounding box test. The combined coverage mask indicates a plurality of pixels that are covered by the graphics primitive. The combined coverage mask is divided into a plurality of sub-portions. The sub-portions are allocated to a plurality of raster components to determine sub-pixel coverage for the sub-portions.
