Low granularity coarse depth test efficiency enhancement
Briefly, in accordance with one or more embodiments, an apparatus comprises a processor to compute depth values for one or more 4×4 blocks of pixels using 16 source interpolators and 8 destination interpolators on an incoming fragment of pixel data if the destination is in min/max format, and a memory to store a depth test result performed on the one or more 4×4 blocks of pixels. Otherwise the processor is to compute depth values for one or more 8×4 blocks of pixels using 16 source interpolators and 16 destination interpolators if the destination is in plane format.
