Product Description 1.5 Intel® G965 Express Chipset The Intel G965 Express chipset consists of the following devices: • Intel 82G965 Graphics and Memory Controller Hub (GMCH) with Direct Media Interface (DMI) interconnect • One of the following: ⎯ Intel 82801HR I/O Controller Hub (ICH8R) with DMI interconnect ⎯ Intel 82801HH I/O Controller Hub (ICH8DH) with DMI interconnect The GMCH component provides interfaces to the CPU, memory, PCI Express, and the DMI interconnect. The component also provides integrated graphics capabilities supporting 3D, 2D and display capabilities. The ICH8 is a centralized controller for the board's I/O paths. For information about The Intel QG65 Express chipset Resources used by the chipset Refer to http://developer.intel.com/ Chapter 2 1.5.1 Intel G965 Graphics Subsystem The Intel G965 Express chipset contains two separate, mutually exclusive graphics options. Either the GMA X3000 graphics controller (contained within the 82G965 GMCH) is used, or a PCI Express x16 add-in card can be used. When a PCI Express x16 add-in card is installed, the GMA X3000 graphics controller is disabled. 1.5.1.1 Intel® GMA X3000 Graphics Controller The Intel GMA X3000 graphics controller features the following: • 667 MHz core frequency • High performance 3-D setup and render engine • High quality texture engine ⎯ DX9.0c* & DX10 and OpenGL 1.5 compliant ⎯ Hardware Pixel Shader 3.0 ⎯ Vertex Shader Model 3.0 ⎯ 32-bit and 16-bit Full Precision Floating Point Operations ⎯ Occlusion query ⎯ 128-bit floating point texture formats ⎯ Bilinear, trilinear, and anisotropic MipMap filtering ⎯ Shadow maps and double sided stencils ⎯ Alpha and luminance maps ⎯ Texture color-keying/chroma-keying ⎯ Cubic environment reflection mapping ⎯ Enhanced texture blending functions 23
