QUICK REFERENCE GUIDE TO INTEL INTEGRATED GRAPHICS

Chipset Naming Conventions

Chipsets are classified broadly based on the platforms and the intended market segment that they would be used in. Currently, we have desktop, notebook, server and workstation, embedded and consumer electronics chipsets. In this article, we would be concentrating on the desktop and notebook chipsets and detailing the differences between the Intel Integrated Graphics solutions offered in these chipsets.

The following Intel chipset products page would be a good starting point to learn about the various chipset offerings and their detailed technical specifications.

Intel GMA 3x00 and X3x00 Series Graphics

The following table illustrates the growth of the graphics capabilities supported by the 965 series chipsets. When combined with the Intel Core Duo Processors, the Intel 965 series chipset delivers fast system-level performance and responsiveness. Table 1 provides a detailed breakdown of the 3D Graphics features supported by the chipsets that contain the GMA 3x00 and X3x00 series graphics core.

Table 1: Intel GMA 3x00 and X3x00 series 3D Graphics Features

The Intel GMA X3000 provides the ability to perform 32-bit floating-point operations for vertex and pixel shaders and texture operations. With the introduction of the latest drivers (August 2007) for the Intel GMA X3000 series, we get full programmability of hardware vertex processing and vertex and pixel shaders supporting Shader Model 3.0. While the hardware support for Shader Model 4.0 is present for Intel GMA X3100 and X3500, the software driver support is expected in the first quarter of 2008.

Today's digital home consumers are demanding high-quality video playback and sharp image quality from their PC. Intel Graphics with Intel Clear Video Technology provides advanced processing capabilities to enable a richer entertainment experience. Intel Graphics also support the latest in high-definition formats including HD DVD and Blu-ray. Table 2 provides a detailed chart of the video features supported in the latest Intel Integrated Graphics offerings.

3 - HD-DVD or Blu-ray disc media playback requires the use of a third-party decoder card and appropriate software drivers.

4 - Intel Clear Video Technology, including improved video playback and quality are available only on the Intel G965, G33, and G35 Express Chipsets, and the Mobile Intel GM965 and GL960 Express Chipsets.

5 – HW accelerated MPEG-2 VLD not currently supported on Windows Vista* due to OS issue (to be resolved in Vista* SP1).

6 - HW accelerated WMV9b/VC-1 not supported on Windows Vista* until August 2007.

7 - Ability to play back AVC/H2.64 content is dependent on system configuration, content bitrate and resolution.
