3D and Video Engines for Graphics Processing
The Gen 7.5 3D engine provides the following performance and power-management
enhancements.
3D Pipeline
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.
3D Engine Execution Units
• Supports up to 20 EUs. The EUs perform 128-bit wide execution per clock.
• Support SIMD8 instructions for vertex processing and SIMD16 instructions for
pixel processing.
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*.
