Abstract: Briefly, in accordance with one or more embodiments, a processor performs a coarse depth test on pixel data, and performs a final depth test on the pixel data. Coarse depth data is stored in a coarse depth cache, and per pixel depth data is stored in a per pixel depth cache. If a result of the coarse depth test is ambiguous, the processor is to read the per pixel depth data from the per pixel depth cache, and to update the coarse depth data with the per pixel depth data if the per pixel depth data has a smaller depth range than the coarse depth data.

Abstract: Described herein is a data processing system comprising a memory device to store a multisample render target and a general-purpose graphics processor comprising a multisample antialiasing compressor and a multisample render cache. The multisample render target can store color data for a set of sample locations of each pixel in a set of pixels. The multisample antialiasing compressor can apply multisample antialiasing compression to color data generated for the set of sample locations of a first pixel in the set of pixels. The multisample render cache can store color data generated for the set of sample locations of the first pixel in the set of pixels. Color data evicted from the multisample render cache is stored to the multisample render target.
