AGP
AGP stands for Accelerated Graphics Port and designates an expansion slot on the motherboard that is used to connect a display adapter. What is special about AGP is that it makes system memory available to the graphics card for storing display data.
More precisely, a direct connection between the memory on the graphics card and the system memory is reserved so that data can be transferred between the two memory areas directly.
This enables images to be displayed more quickly and smoothly than in conventional systems where data is transferred over the standard bus (usually the PCI bus).
Another advantage of AGP is that complex image elements such as textures can be stored in system memory. With conventional graphics cards, on the other hand, these elements had to be stored in the memory on the adapter itself for rapid access, and more dedicated memory was necessary.
AGP graphics cards, therefore, can get by with less dedicated graphics memory. The AGP's clock speed is 66 or 133 MHz (the PCI bus runs at only 33 MHz). Data transfer speeds can reach up to 533 MB per second. In order to use AGP, a special system board with an AGP chipset is required in addition to an AGP display adapter.
