Accelerated Graphics Port

hardware (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.
