Product Description 1.7 Intel® Q965 Express Chipset The Intel Q965 Express chipset consists of the following devices: • Intel 82Q965 Graphics and Memory Controller Hub (GMCH) with Direct Media Interface (DMI) interconnect • Intel 82801HO I/O Controller Hub (ICH8DO) 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 ICH8DO is a centralized controller for the board's I/O paths. For information about The Intel Q965 Express chipset Resources used by the chipset Refer to http://developer.intel.com/ Chapter 2 1.7.1 Intel Q965 Graphics Subsystem The Intel Q965 Express chipset contains two separate, mutually exclusive graphics options. Either the GMA 3000 graphics controller (contained within the 82Q965 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 3000 graphics controller is disabled. 1.7.1.1 Intel® GMA 3000 Graphics Controller The Intel GMA 3000 graphics controller features the following: • 667 MHz core frequency • High performance 3-D setup and render engine • High quality texture engine ⎯ DX9.0c* and OpenGL* 1.4 + extensions compliant ⎯ Vertex Shader Model 2.0 / 3.0 (Software Only) ⎯ Hardware Pixel Shader 2.0 ⎯ 32-bit and 16-bit Full Precision Floating Point Operations ⎯ Up to eight Multiple Render Targets (MRTs) ⎯ 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 • 3D Graphics Rendering enhancements ⎯ 1.3 dual texture GigaPixel/sec fill rate ⎯ 16 and 32 bit color 27
