<p>A 3D graphics pipeline includes a prefetch mechanism that feeds a cache of depth tiles. The prefetch mechanism may be predictive, using triangle geometry information from previous pipeline stages to pre-charge the cache, thereby allowing for an increase in memory bandwidth efficiency. A z-value compression technique may be optionally utilized to allow for a further reduction in power consumption and memory bandwidth.</p>
