The advent of PCI Express has afforded component makers that use that interconnect a number of benefits over PCI, PCI-X and AGP. For example, disk controller vendors can engineer RAID controllers that aren't limited by the PCI or PCI-X bus for transfer rates to and from the host. For graphics chip vendors, the benefits are twofold. Firstly, with a full 16-lane PEG16X implementation of PCI Express, you get double the bus bandwidth to the graphics chip and around sixteen times the bandwidth transferring data from the GPU back to the host. Secondly, the PCI Express spec allows granular access to system memory from any device that uses it.
