Systems, apparatuses and methods may provide a way to track graphics pipeline operations. More particularly, the systems, apparatuses and methods may provide a way to track operation dependencies between graphics pipeline operations for blocks of pixel samples and stall one or more of the pipeline operations based on the operation dependencies. The systems, apparatuses and methods may further provide cache pre-fetch hardware to monitor processing of blocks of pixel samples and fetch a next block of the pixel samples from the memory into a cache before completion of processing a current block of pixel samples based on one or more of the pipeline operations or a surface state of one or more regions of a screen space.
