While running through the information we recorded from the Intel Developer Forum
this past week in San Francisco, we didn't comment really on PCI Express 3.0 but wanted to share some additional details from IDF. While native PCI Express 2.0 graphics cards aren't even available yet, PCI Express 3.0 will over twice the bandwidth of PCI Express 2.0, which makes PCI-E 3.0 four times the bandwidth of PCI-E 1.0. PCI Express 3.0 also supports data re-usage, dynamic power management, backwards compatibility, and atomic operations. The release specifications for PCI Express 3.0 will be available in 2009 while PCI-E 3.0 products aren't expected until 2010. Meanwhile, Intel's Xeon 5400 Chipsets and Intel's X38 Express Desktop Chipset will support PCI Express 2.0 this year.
