Intel® HD Graphics Controller
This section details the 2D, 3D and video pipeline and their respective capabilities.
The integrated graphics is powered by a refresh of the fifth generation graphics core
and supports twelve, fully-programmable execution cores. Full-precision, floating-point
operations are supported to enhance the visual experience of compute-intensive
applications.The integrated graphics controller contains several types of components;
the graphics engines, planes, pipes, port and the Intel FDI. The integrated graphics has
a 3D/2D Instruction Processing unit to control the 3D and 2D engines respectively. The
integrated graphics controllers 3D and 2D engines are fed with data through the IMC.
The outputs of the graphics engine are surfaces sent to memory, which are then
retrieved and processed by the planes. The surfaces are then blended in the pipes and
the display timings are transitioned from display core clock to the pixel (dot) clock.

3D and Video Engines for Graphics Processing
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 5.75 3D engine provides the
following performance and power-management enhancements:

following performance and power-management enhancements:
Execution units (EUs) increased to 12 from the previous 10 EUsin Gen 5.0.
Includes Hierarchal-Z
Includes video quality enhancements
2.4.1.1
3D Engine Execution Units
Support 12 EUs. The EUs perform 128-bit wide execution per clock.
