Conclusion

Such is the working – except for a few details – of the GPU. Now we know why it is the most important component of the graphics board. What is the course carried out in the GPU? A vertex contains information, and each vertex is a top of a form called Primitive. After the tesselation, all the data go through the vertex pipeline, and leave it for a series of operations improving performance. Then the pixel pipeline deals with carrying out the operations necessary to bind the pixels with their data. Then at the end of the treatment, several tests will aim at increasing performances by removing the superfluous pixels, and also at creating fog and managing transparency. Now the working of the graphics processor no longer enclose any secret for you;-).
