Windows device driver information for SiS Accelerated Graphics Port

The SiS Accelerated Graphics Port, otherwise called the Advanced Graphics Port, is a high-speed and advanced point-to-point channel used to attach a video card to the PC's motherboard. Mainly, its job is to assist in accelerating 3D computer graphics. Since 2004, the SiS Accelerated Graphics Port has been phased out progressively in favor of the new PCI Express. In the middle of 2009, PCIe cards have dominated the market; however, new AGP cards such as the newer models of the SiS Accelerated Graphics Port are still available in the market. As computers increasingly became graphically-oriented, substantial generations of graphic adapters such as the SiS Accelerated Graphics Port began pushing the limits of PCI, a bus that contains a shared bandwidth. This has led to the introduction of the SiS Accelerated Graphics Port. The SiS Accelerated Graphics Port supports the SiS Mirage 3 Graphics.

The main advantage of using the SiS Accelerated Graphics Port over the SiS PCI is that it gives the user a more committed pathway between the processor and slot, rather than having the PCI bus shared. Aside from the lack of bus contention, the point-to-point connection of the SiS Accelerated Graphics Port allows higher clock speeds. The SiS Accelerated Graphics Port also makes use of sideband addressing, which means that data buses and addresses are separated so that the whole packet does not require to be read just to get the addressing information. This is possible by using 8 extra 8-bit buses that allow the issuing of a new AGP request given to the graphics controller. This results in an improved and more efficient AGP data throughput. It is highly recommended you run a free registry scan for and SiS Accelerated Graphics Port errors before installing any driver updates.
