* 8/4 - which is it ?

From NVIDIA themselves: The NV30/35 runs at 8 operations per clock for the following scenarios.

z-rendering
stencil operations
textures operations
shader operations

But color + z pixel rendering is done at 4 operations per clock. This is by far the most common usage in today's games. 8-pipeline running may come into play in the future, though it's a decidedly 4-pipeline approach for today.
