The PCI-SIG announced today that the final version of the PCI Express Base 2.0 Specification is now out and available to members. Version 0.9 of the spec was released back in October of 2006, and today's release of the final version means that the spec is officially ready for prime time. Indeed, pretty soon it'll be time for me to dust off the old PCI Express article and update to v2.0.

PCIe 2.0 adds a number of enhancements that make the spec more useful for the kinds of coprocessor hosting that PCIe is increasingly being pressed into service for. At the top of the list is increased signaling speed (5GHz) that results in increased per-link bandwidth. Specifically, each lane doubles from 2.5 GT/s under the PCIe 1.1 spec to 5 GT/s under the 2.0 spec, with the result that a PCIe 2.0 x16 link has a peak bandwidth of 16 GB/s.

so now a x8 pci-ex2 slot will have the same benefits and capabilities of a x16 pci-ex slot...

hmmm, that could really get the quad pci-ex2 cards for sli/physics flying no?
