Accelerated Graphics Port interface
     The AGP interface is a new platform bus specification that enables high performance graphics capabilities. This interface specification will enable 3D applications, which not only require sufficient information storage so that the monitor image may be refreshed, but also enough storage to support texture mapping, z-buffering and alpha blending. It will allow 3D applications to run faster and to look better. The Accelerated Graphics Port interface adds new features for graphics accelerators like dedicated pipelined access to main memory and faster transfer rates. This provides a high bandwidth, low latency connection to system memory. The AGP interface enables the use of main memory for texturing, z-buffering, and alpha blending providing the benefits of high performance three-dimensional graphics.
     AGP functions at 66MHZ by default on a 32bit bus. AGP 1X operates in a traditional fashion while AGP 2X is a "double pumped" solution transmitting data on the rising and falling edges of the clock signal for effectively double the throughput.

Bandwidth Breakdown
  • AGP 1X = 66MHZ, 266MB/sec
  • AGP 2X = 133MHz, 533MB/sec
  • AGP 4X = 266MHz, 1.066GB/sec
  • AGP 8X = 528MHz, 2.000GB/sec
