PCI-SIG announces availability of PCI Express Base 2.0 specification

PCI-SIG is the group responsible for PCI Express industry-standard I/O technology. They have now announced the availability of the PCI Express Base 2.0 specification.

The group conducted a 60-day review of revision 0.9 of the specification in Fall 2006. And the members have now finalized and released PCI Express (PCIe) 2.0.

This specification doubles the interconnect bit rate from 2.5GT/s to 5GT/s to support high-bandwidth applications.

This specification further extends the data rate to 5GT/s in a manner compatible with all existing PCIe 1.1 products currently supporting 2.5GT/s signaling.

Another benefit of this new specification is faster signaling which increasing the aggregate bandwidth of a 16-lane link to approximately 16 GB/s.
