Accelerated Graphics Port
AGP
AGP graphics

    (AGP) A bus specification by Intel
   which gives low-cost 3D graphics cards faster access to
   main memory on personal computers than the usual PCI
   bus.

   AGP dynamically allocates the PC's normal RAM to store the
   screen image and to support texture mapping, z-buffering
   and alpha blending.

   Intel has built AGP into a chipset for its Pentium II
   microprocessor.  AGP cards are slightly longer than a PCI
   card.

   AGP operates at 66 MHz, doubled to 133 MHz, compared with
   PCI's 33 Mhz.  AGP allows for efficient use of frame buffer
   memory, thereby helping 2D graphics performance as well.

   AGP provides a coherent memory management design which allows
   scattered data in system memory to be read in rapid bursts.
   AGP reduces the overall cost of creating high-end graphics
   subsystems by using existing system memory.
