AGP terminology

  [DELETED] 17:46 02 Feb 2006

While I've been finding out about sockets for graphics cards while I've been trying to get my new cards' installation sorted, I've come across AGP 2x/4x/8x. Now I've read about AGP 2.0! I understand all the 2x/4x/8x business, but what's AGP 2.0?

AGP 2.0 defines a new 4x-transfer mode that allows four data transfers per clock cycle on the 66MHz AGP interface. This delivers a maximum theoretical bandwidth between the AGP device and system memory of 1.0 GBps. The new 4x mode has a much higher potential throughput than 100MHz SDRAM (800 MBps), so the full benefit wasn't seen until the implementation of 133MHz SDRAM and Direct Rambus DRAM (DRDRAM) in the second half of 1999. AGP 2.0 was supported by chipsets launched early in 1999 to provide support for Intel's Katmai processor.
