OpenGL ES 2.0 and DirectX all define the depth test step after pixel shader stage, it will cause time consumption and memory usage, so that increase the power usage. Therefore, many mobile GPU vendors likes PowerVR, Nvidia attempt to adjust the graphics pipeline of these APIs. PowerVR provides Hidden-Surface-Removal(HSR) in tile-based-render and Nvidia's ultra low power( ULP) GeForce support the early depth test.
