  1. One of the weaknesses of Peripheral Component Interconnect (PCI) as a graphics connector is that high amounts of data can reach the CPU all at once, resulting in a graphical bottleneck that hampers performance. One of the main functions of Accelerated Graphics Port (AGP) is to clear out these "traffic jams" of data, allowing for faster speeds and more efficient processing. This is accomplished by three factors: first, there is only one AGP, and the only device connected to it is the graphics card. This prevents data from other components from clogging the way for graphical information. AGP also uses a form of data pipelining to process large amounts of data at once with no lag. Finally, it uses a process called sideband addressing to help data reach its destination faster. All three of these factors help your computer process graphics faster and more efficiently.
