PCI was first presented in 1992 by Intel and has since achieved great recognition and distribution in all types of PCs. Now comes the next generation.
PCI bus replaced the ISA bus which was originally introduced by IBM in 1981. The PCI bus was then (in '92) quite revolutionary because it gave high bandwidth compared to the ISA bus and was a 32 bit bus, the ISA bus was only 8 or 16 bits. Since then, the PCI bus expanded to include 64-bit versions and 33/66/133 MHz speeds.
but as bandwidth requirements increase - most with the ever more powerful graphics card - tried producers to make good the PCI bus senescence - eg. with AGP bus, which with its more modern specifications featured a theoretical bandwidth, there were up to eight times faster than PCI. Later came other new technologies - including PCI-X, X-EPCI (Embedded PCI-X, combining 2 or 3 pieces. 32-bit PCI slots for use with, for example. CPU board) and Infiniband. PCI-X and EPCI X has only gained ground in the server area, and Infiniband are not the direct successor of the PCI bus, so these may be expected to coexist for some years yet.
