The graphics/video features are divided into two sections:

• 3D Graphics Features
• 2D Graphics Features

• Full OpenGL* 1.3 ICD (Installable Client Driver)
• Compatible with DirectX* 9.0, 8.x, and 7.x
  • Not all of the new features of DirectX 9.0 are supported
• 32 bpp True Color 3D Support
  • Allows for high quality textures and rendering
• 3D Performance Features
  • 200MHz Core Graphics Clock
  • Support for DDR SDRAM memory improves 3D video memory performance
    • DDR SDRAM gives a large performance boost in 3D, which is even noticeable between PC1600 and PC2100 memory.
    • Since the frame buffer, depth buffer, and textures must all share memory bandwidth, increasing the bandwidth gives large gains in 3D performance.
  • Zone Rendering Technology
    • Renders the 3D scene in pieces to reduce the required memory bandwidth for a given scene
    • Zone Rendering White Paper
• 3D Setup and Render Engine
  • Triangles, Strips, and Fans
  • Pixel Accurate Fast Scissoring and Clipping Operation
  • Backface Culling
  • Anti-aliased Lines (OpenGL only)
  • Sprite Points
