Reduced bitcount polygon rasterization

Techniques are disclosed for carrying out rasterization of a given graphics workload, wherein portions of the workload associated with relatively high bit count operations are processed via a first process path, and portions of the workload associated with relatively lower bit count operations are processed via a second, relatively faster process path, in accordance with an embodiment. In a more general sense, maximal bit count associated with a given primitive can be identified and compared to a threshold to determine which one of multiple available processing paths can be used.
