What is an accelerated graphic port?
In the world of computers is one of the things that the word port can refer to, physical interface or point of access on the motherboard or system board. The port is in the form of a slot into which the expanding board or graphics card appears in the movement, which is often described as pushing toast down into the toaster. Accelerated graphics port (AGP), made by Intel®, is one type of slots that can appear on the motherboard, for example together with PCI slots (connection of peripheral components). The accelerated graphics port has been developed to show 3D graphics faster and smoother on the base computer than previously possible, but most newer motherboards have PCI Express (PCI-E or PCIE) instead.
In 1996, when the accelerated graphics port was released, the data transfer rate on the tip was one of the key differences. Until 2003, data transfer speed for PCI was up to 133 Mbps. (Megabytes per second). AGP provided the transfer speed of datum 533 Mbps. With AGP 8x was the speed of theThought at 2 Gbps (gigabytes per second). AGP also differs from the PCI in that it is a dedicated connection of Point-to-Point, which connects a graphics card with a CPU rather than connecting the bus used PCI.
The accelerated graphic port differs from PCI in several other ways, all of which tend to optimize graphics processing. First, it is a reserved port that connects exclusively with the graphics card. Secondly, graphic information from PCI is not pipe, while AGP is: with non -shaped processing the information is transmitted gradually, each detail waiting for the previous processing; When processing pipes, one request can contain multiple data packets. Thirdly, the technique of addressing the side zone has changed the way in which data packet information, acceleration processing, and reduce the width width. Another accelerated procedure of the graphic port was to allow OS (operasAinging system) to mark RAM to be reserved for using a graphics card. This reduces the load on the graphics card memory and includes more RAM in graphics processing.
