Successor to the PCI bus
Louis Burns, Vice President of Intel, introduced the end of the PCI bus at his keynote. The role of the PCI bus will be given a new type of serial bus in the future. Burns justifies this with the fact that the PCI bus with its maximum of 66 MHz is no longer up-to-date for processors that are clocked beyond the 1 GHz limit.
Intel will therefore be at the next IDF in autumn introduce a novel I/O architecture for all future platforms. The architecture will be based on a serial point-to-point connection, whereby the bus can work with a clock rate of over 10 GHz. Burns also mentioned that today's copper railway lines can only be used up to a maximum of 12 GHz. One could conclude from this that the basic versions of the new bus will work with copper railway lines, but later extensions will work with optical lines. This is made even easier by the fact that it is relatively easy to change the transmission medium on the serial bus
