Features
The 3D graphics pipeline architecture simultaneously operates on different primitives or
on different portions of the same primitive. All the cores are fully programmable,
increasing the versatility of the 3D Engine. The Gen 7.0 3D engine provides the
following performance and power-management enhancements:

12.7.2.1
Vertex Fetch (VF) Stage
The VF stage executes 3DPRIMITIVE commands. Some enhancements have been
included to better support legacy D3D APIs as well as SGI OpenGL*.

12.7.2.2
Vertex Shader (VS) Stage
The VS stage performs shading of vertices output by the VF function. The VS unit
produces an output vertex reference for every input vertex reference received from the
VF unit, in the order received.
