From Intel's site -
Intel Graphics Media Accelerator 900 (Intel® GMA 900 graphics) can deliver over 1.5 times faster performance than previous Intel graphics.¹ It also features acceleration for Microsoft* DirectX* 9 for 3D performance.
The Intel® 915G Graphics and Memory Controller Hub (GMCH) provides a variety of display interfaces. Intel GMA 900 graphics has an integrated DAC, two Intel® Serial Digital Video Out (SDVO) ports that can interface to DVI and LVDS transmitters, SD/HDTV-out encoders and additional DACs.
Intel GMA 900 graphics offers driver support for a variety of operating systems - Microsoft Windows* 2000, Windows* XP, Windows* XP Media Center Edition, Mandrake Linux*, Red Hat Linux*, SuSe Linux*, Red Flag Linux*, and IBM OS/2*.
| While the graphics subsystem for a discrete graphics device is mostly contained on a PCI, AGP, or PCI Express* Graphics card, the graphics subsystem in an integrated graphics solution, such as Intel GMA 900 graphics, uses the CPU, the GMCH, system memory, and different display interfaces. As a result, Intel GMA 900 graphics is designed to take full advantage of the power an Intel® Pentium® 4 processor brings to the PC. The CPU is used for the first stage of 3D processing (geometry operations), while the integrated graphics device handles the rest of the 3D processing. Intel GMA 900 utilizes system memory for both system and graphics usage, balancing both usages for optimal performance. |

Intel GMA 900 is the next step in the evolution of Intel graphics. In addition to running the graphics engine at 333 MHz, Intel GMA 900 has four pixel pipelines which provide a fill rate of 1.3 GP/s, enabling an excellent consumer gaming experience. The 3D graphics pipeline is broken up into four major stages: geometry processing, setup (vertex processing), texture application and rasterization. Intel GMA 900 graphics is optimized by using current and future Intel® processor family for advance software based transform and lighting (geometry processing) as defined by Microsoft Direct X*. The other three stages of 3D processing are handled by Intel GMA 900. |

| Zone Rendering Technology 3 (ZRT3) is a tile-based rendering system designed to reduce memory bandwidth consumption and maximize rendering performance. ZRT3 aims to improve texture processing bandwidth by only performing texture processing on pixels that will be seen by the viewer (that are not hidden by other pixels). ZRT3 also strives to improve memory efficiency by reducing memory traffic and texture processing. |
