GeForce 6800 GPU's pipeline dissected

The folks at 3DCenter have published the first installment of their look at the NV40 pipeline. This article focuses on the pixel shader units, explaining what they do and how their internal organization differs from those of other GPUs. This quick examination of the parallelism inside NV40's pixel shader units helps explain how NVIDIA's new baby can sometimes match or beat a Radeon X800 while running at lower clock speeds.
Tip: You can use the A/Z keys to walk threads.
