Recently, the member organizations of the PCI Special Interest Group (PCI-SIG) ratified the new PCI Express 2.0 standard specifications. The new standard introduces a dramatic speed increase with the interconnection rate on the bus doubling from the current 2.5GT/s to 5GT/s.

The new standard introduces a dramatic speed increase with the interconnection rate on the bus doubling from the current 2.5GT/s to 5GT/s. In addition to pure speed, the new standard also introduces a feature called input/output virtualization. The new feature will be key in allowing virtual machines to communicate directly with the physical components located on the PCI Express 2.0 bus. Doing so could mean that the guest operating system would then be able to finally recognize and communicate with the 3D processor on the physical graphics card. Finally, virtual machines would be able to run 3D applications, demanding front ends such as Vista’s Aero, and yes, even the important things like 3D gaming. Software Development
