	Accelerated Graphics Port - Wikipedia, the free encyclopedia
		AGP 1x, using a 32-bit channel operating at 66 MHz resulting in a maximum data rate of 266 megabytes per second (MB/s), doubled from the 133 MB/s transfer rate of PCI bus 33 MHz / 32-bit; 3.3 V signaling.
		AGP slots are superior to PCI for graphics cards because they provide a dedicated pathway between the slot and the processor, allowing for faster communication between the two.
		In addition, AGP uses sideband addressing, meaning that addressing for packets is carried outside of the packet, meaning that the entire packet does not need to be read to get addressing information.

	Troubleshooting AGP
		AGP 1.0 was introduced in 1996 and provided the 1X and 2X speeds which are two and four times as fast as a standard PCI slot.
		The AGP signaling voltage is the voltage of the signal used to transfer data between the AGP card and the motherboard.
		AGP adjustments made in the BIOS should be very reliable so if nothing else is working, then look around in the BIOS for an option which lets you set the maximum AGP speed or enable/disable fast writes.

		Original AGP cards were "1x" versions that ran at 66MHz, offering 266MB/second throughput; but now AGP supports up to 8X data transfer speeds, which means the card still runs at 66MHz, but transfers 8x as much data per clock tick, upping the throughput to 2.1GB/second.
		AGP 1x - The original parallel AGP standard that operates on a 32-bit bus at 66MHz speed for a maximum data transfer rate of 256MB/second.

	DRI Wiki - AGP
		AGP is a dedicated high-speed bus that allows the graphics controller to fetch large amounts of data directly from system memory.
		This implies that the traffic on the AGP tends to be long, sequential transfers, serving the purpose of bulk data transport from system memory to primary graphics (local) memory.
		An additional mechanism is required to allow clients to know which pieces of their AGP buffer is pending execution by the hardware, and which pieces of the buffer are available to be reused.

	What is Accelerated Graphics Port? - a definition from Whatis.com - see also: AGP
		AGP is designed to convey 3-D images (for example, from Web sites or CD-ROMs) much more quickly and smoothly than is possible today on any computer other than an expensive graphics workstation.
		AGP offers high-speed data transfer to and from RAM, optimizing the use of memory and minimizing the amount of memory necessary for high-performance graphics.
		The AGP main memory use is dynamic, meaning that when not being used for accelerated graphics, main memory is restored for use by the operating system or by other applications.

	Accelerated Graphics Port - AGP
		Designed by Intel, August of 1997 AGP introduces a dedicated point-to-point channel so that the graphics controller can directly access the system memory.
		The AGP aperture size is an available option configurable commonly through the computer BIOS that is commonly set to a default of 64MB.
		AGP aperture size defines how much system memory the AGP controller is allowed to use for texture maps.

	The ABCs of Graphics Cards
		The AGP bus, introduced by Intel in 1996, is a dedicated graphics connection used only by an AGP graphics card and is supported by most motherboards.
		For example, the data rate for AGP 1X mode (66MHz = 264 MB/sec) is twice as fast as that of PCI (33MHz = 132MB/sec), while AGP 2X mode (133 MHz = 528 MB/sec) is four times faster than PCI.
		As far as system buses are concerned then, AGP would definitely appear to be the highway to the future, especially given all the graphics-intensive 2D, 3D, and video applications that we run on our PCs today.

	AnandTech: AGP Explained (Site not responding. Last check: 2007-11-07)
		AGP is much more than a mere "extension" of the PCI bus, many of you know that the PCI bus currently runs at a horrible 33MHz which is one of our most commonly experienced bottlenecks.
		AGP accomplishes this as well as higher sustained transfer rates by sideband transfers and pipelining so it can constantly transfer data without having to wait for another part of the system to transfer it.
		AGP on the other hand, provides a fast path to the system RAM so you don't have to worry about how much local RAM you have and you don't really have to worry about the speed at which it will be accessed.
