Final PCI-Express 3.0 Specifications revealed

The PCI-SIG annonced the final specifications of PCI-Express 3.0 bus .
Like PCI-Express 1.x and PCI-Express 2.x, PCI-E 3.0 is designed to be backwards-compatible with devices that use older versions of the bus. Keeping up with the major version trend, PCI-E 3.0 doubles the theoretical bandwidth. PCI-Express 3.0 can push 1 GB/s per lane, per direction, double that of PCI-E 2.0. A PCI-Express 3.0 x16 slot would hence have its cumulative bandwidth at 32 GB/s.


With 8 GT/s Vs 5GT/s on the 2nd Generation , with its overhead the PCI-Express uses the new 128b/130b data encoding scheme, allowing near-100% utilization of available bandwidth on the slot .
