Important information Today it’s in my opinion a bit obsolete to talk about “pixel pipelines†when talking about the latest generation of video cards (R5XX and G7X). This is why I have decided to include: pixel shader units, TMUs, ROPs (z compare units are a part of a ROP) and vertex shader units. â€A Pixel shader unit calculates different effects for a displayed pixel to create realistic materials and surfaces. In general one could say that the more pixel shader units exists the better the performance would be. Not all games uses the same amount of shaders, therefore the performance will fluctuate between them†â€The most basic explanation of the fuction of a Texture Mapping Unit (TMU) is that it uses a 2D-image to “clothe†a 3D figure. â€A Render Output Unit or Raster Operations Pipeline (ROP) is one of the final steps in producing the final result. The ROP takes care of the transformation of information stored in the GPUs memory into pixels which are displayed on a monitor. The basic task for a ROP is: AA, blending (just explained) and z-buffer de-/compression.†â€The basic task for a vertex shader unit is to control the behaviour and appearance of the corners to the triangles which 3D-objects are build upon†â€Unified shader unit (called â€stream processor†by nVidia) can do pixel, vertex and with time geometry (a DX10 feature) shading.†|
