Pixel pipeline
From Wikipedia, the free encyclopedia
A pixel pipeline is a videocard part that transfers pixel information. The more pixel pipelines, the faster the video card can process pixels.
Current top-end videocards, such as the Radeon X1900 XTX and the GeForce 7950 GX2, offer 16 (effectively 48, 3 pixel processors per pipe) and 2x24 pixel pipelines respectively.
Current videocards and their number of pipelines:
