AGP

(Accelerated Graphics Port) An earlier hardware interface from Intel for connecting a graphics card (display adapter) to a PC. Introduced in 1997 and superseded by PCI Express in the late 2000s, a single AGP slot on the motherboard provided a direct connection between the card and memory. AGP was introduced as a higher-speed alternative to PCI, and it freed up a PCI slot for another peripheral device.

The original AGP standard (AGP 1x) provided a data transfer rate of 264 MB/sec. AGP 2x, 4x and 8x increased the rate to 528 MB/sec, 1 GB/sec and 2 GB/sec. See AIMM, PCI Express, PC data buses and motherboard.


AGP and PCI Slots
The brown AGP receptacle sat about an inch farther back from the PCI slots. There was only one AGP slot on the motherboard for the graphics card.







From AGP to PCI Express (PCIe)
The 32-bit AGP bus gave way to 16-channel PCI Express (PCIe). For a while, motherboards had one PCIe slot just for the graphics card. Later on, boards offered multiple PCIe slots.

There are many low cost PCs available on the market today for well under $1000, many without an AGP port.
To further enhance performance, Angelo provides two communications pathways between it and the host board: a standard 32-MHz PCI bus, and a 66-MHz AGP port that enables the baseboard to pass video/graphics data to and from Angelo at high speeds without tying up the PCI bus.
Based on the 440BX AGPset, the Pentium II 450MHz processor eliminates bottlenecks and also increases the width and depth of buffers to the system bus, AGP port, PCI bus and SDRAM components for exceptional data throughput and all-around best computation.
Within a few years," according to Savadatti, "new and exciting 3D and video applications will demand high rates of memory for both increasingly fast main system processors and a graphics processor through an AGP port.
In addition to its 32-bit AGP port and two Ultra DMA/33 IDE ports for support of up to four IDE devices, the Stallion features three 32-bit PCI, and four 16-bit ISA expansion slots (one shared).
