PCI Express 3.0 base spec to be ready by November

Now that newer PCs are rocking PCI Express 2.0 slots, it's time for an upgrade, don't you think? EE Times reports that PCI-SIG will complete the PCI Express 3.0 base spec by November, having released a 0.9 version of the specification for review about a month ago.

PCIe 3.0 will enable data rates up to 8GT/s. According to PCI-SIG, that will translate into top speeds of 1GB/s per lane per direction, or 32GB/s for a x16 link—essentially twice as fast as PCIe 2.0 and four times as fast as the first-gen standard. EE Times expects PCIe 3.0 to come in handy for high-end graphics cards, upcoming 40Gbps Ethernet adapters, and high-end solid-state drives.

As far as real-world products go, EE Times quotes PCI-SIG's Al Yanes as saying products "typically" come out "about a year after the spec becomes final." However, some firms will reportedly have devices out a little early—like Mellanox Technologies, which will have 40Gbps Infiniband adapters based on the new interface by June. Word is that Intel's server-oriented Sandy Bridge CPUs will support PCI Express 3.0 "before the end of 2011," as well.
