Abstract
Embodiments are generally directed to a multi-phase architecture for multiple rate pixel shading. An embodiment of an apparatus includes one or more processor cores, the one or more processing cores including a graphics pipeline and a memory to store data for graphics processing, the data including pixel data. The graphics pipeline includes a multi-phase shader for processing of pixel data, the multi-phase shader including multiple rendering stages, the rendering stages including at least a first stage for a first granularity and a second stage for a second, different granularity, the second rendering granularity being a finer granularity than the first rendering granularity. The multi-phase shader is structured to provide a hierarchy for image rendering, wherein pixel data is received at a rendering stage having a coarsest rendering granularity, with remaining pixel data being provided through the hierarchy to one or more rendering stages having finer rendering granularities.
