The first graphics cards from NVIDIA with a PCI Express 2.0 interface will arrive within about 2 months. OCW reports the GeForce 8500GT, 8600GT, 8600GTS and 8800GTX will all get PCI Express 2.0 in October.
The PCI Express 2.0 specification extends the data rate of PCI Express to 5GT/s (5GHz) in a manner compatible with the existing PCI Express 1.1 specifications that support 2.5GT/s (2.5GHz) signaling. There are a number of improvements made to the protocol and software layers of the architecture – a product of more than three years of design experience by the PCI-SIG members.
Currently, the Intel P35 chipset already supports the PCI Express 2.0 spec. Upcoming new chipset AMD RD790 will also support this new spec.
