Abstract: Methods, systems and apparatuses may provide for hardware sampler technology that determines mip region dimensions of a feedback map based on a description of the feedback map, identifies accessed texels in a texture based on a view of a resource that is paired with the feedback map, and records the accessed texels in the feedback map based on the mip region dimensions.

Abstract: Position-based rendering apparatus and method for multi-die/GPU graphics processing. For example, one embodiment of a method comprises: distributing a plurality of graphics draws to a plurality of graphics processors; performing position-only shading using vertex data associated with tiles of a first draw on a first graphics processor, the first graphics processor responsively generating visibility data for each of the tiles; distributing subsets of the visibility data associated with different subsets of the tiles to different graphics processors; limiting geometry work to be performed on each tile by each graphics processor using the visibility data, each graphics processor to responsively generate rendered tiles; and wherein the rendered tiles are combined to generate a complete image frame.
