The PCI-special interest group (SIG) has just released a new revision of the PCI Express Base 2.0 specification to its member companies for testing.

The revision is the last incarnation before the final specification of the new high-speed PCI-E bus is published and made available for wide-scale use.

The SIG is a non-profit electronics consortium responsible for specifying the Peripheral Component Interconnect (PCI) buses.

These buses are used on computer motherboards and allow expansion cards to function with the other components inside the machine.

Some of the SIG’s member companies are ATi, Intel, IBM, nVidia and Microsoft.

The latest revision has been in development for three years and is designed to better meet the demands of graphics companies.

Version 2.0 offers faster signaling rates of 5GB/s, as opposed to just 2.5GB/s offered by the older version, PCI-SIG claimed.

This means graphics cards can communicate with a PC’s other components (such as the CPU) more quickly thanks to the added bandwidth, which will mean faster overall graphics performance.
