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