Intel has been promising their advanced graphics port during the year. Now, with the release of new chipsets Pentium-II LX, it's finally here. AGP is a new type of bus design. On the computer motherboard, there are two types of expansion slots, ISA and PCI. ISA is an ancient form an expansion slot, and the majority of expansion cards today use the new PCI bus. With Advanced Graphics Port, Intel has developed a slot only for graphic cards.

Prior to AGP, most video cards use the PCI bus with several older graphics cards on the bus ISA. PCI bus running at 33 MHz, half of the system speed (66 MHz). Running at 33 MHz, PCI can have a maximum transfer rate of 132mb / with Advanced Graphics Port runs at 66 MHz, providing increased data transfer speed 266mb / s (referred to as x1). In addition to a x1 speed data transmission, AGP uses a new technology that doubles the bandwidth by transferring to the rise and fall timings 66 hours MHz to get 532mb / s (referred to as x2). Another advantage of AGP over PCI bus is that the special bus, unlike PCI, which may have other devices occupy its capacity. Increase speed of CPU and memory allow for increased speed of graphics operations (mostly 3D operations).

Another main feature of the Advanced Graphics Port "Direct Memory Run (or DIME). It allows the video card to use part of main memory for texture memory with 3D-graphics. Usually video cards have four megabytes of RAM, with some having eight. DIME allows for 12, 16 or even more accessible to memory by allocating some of the main system memory. Increasing the memory speed increases during the high-resolution graphics with 3D-scenes. Before AGP, high-resolution 3D scene is almost impossible to use with a decent framerate. There were several cards PCI, which offer up to 32 MB of RAM on board,
