Abstract
Methods, systems and apparatuses provide for graphics processor technology that determines whether a first cache line allocated for early depth testing overlaps a second cache line allocated for late depth testing, and when the first cache line overlaps the second cache line, switches the first cache line to be allocated for late depth testing, and bypasses an early depth test for the first cache line. The technology can also compare coordinates of the first cache line with the coordinates of the second cache line, where an overlap is determined when coordinates for at least one pixel in the first cache line match coordinates for at least one pixel in the second cache line. Additionally, the technology can also perform early depth testing on each pixel in the first cache line when the first cache line does not overlap any existing cache lines allocated for late depth testing.
