3.4 Graphics Controller
This chapter details the chipset integrated graphics engines (3D, 2D and Video), 3D pipeline and
their respective capabilities.
The (G)MCH graphics is powered by the Gen 5.0 Graphics Architecture and supports ten fully
programmable execution cores, enabling greater performance than previous generation chipsets.
Mobile Intel® 45 Express graphics supports full-precision, floating-point operations to enhance the
visual experience of compute-intensive applications.
The (G)MCH internal graphics devices (IGD) contain several types of components. The major
components in the IGD are the engines, planes, pipes and ports. The (G)MCH has a 3D/2D
Instruction Processing unit to control the 3D and 2D engines respectively. The IGD’s 3D and 2D
engines are fed with data through the memory controller. The outputs of the engines are surfaces
sent to memory, which are then retrieved and processed by (G)MCH planes.
