Abstract: A graphics processor includes a rasteriser, an early depth tester, a renderer, a late depth tester, and a depth test data buffer that stores depth data values for use by the early and late depth testers. When a fragment is to undergo an early depth test to update the depth buffer, it is first determined whether the fragment should undergo the early depth test to update the depth buffer without waiting for any other fragment to undergo a depth test, or whether the result of a late depth test on a fragment that is still to undergo a late depth test should be awaited before performing a depth test to update the depth buffer on the fragment.
