Definitions

• Fragment Rate: Fragments/sec from Rasterizer

  • Typical numbers for hardware accelerators range from 30M to > 100M
  • Depends on number of triangles rendered per second and average number of pixels per triangle

• FrameBuffer Update Rate

  • [1/(Mem Access Time)] / 2
    • Blends require src pixel and dst pixel so need both a read and write; this is why divide by 2.
    • optimistic, does not account for video access.
