PCI Express - A Preview

Published by

Developed and monitored by PCI-SIG, PCI Express will be the upcoming standard for add on cards in personal computers. The PCI-SIG provides a forum for its 800+ member companies who develop differentiated, interoperable products based on its specifications. PCI Express architecture retains the PCI usage model and software interfaces for investment protection and smooth development migration. The technology is aimed at multiple market segments in the computing and communication industries, and supports chip-to-chip, board-to-board and adapter solutions at an equivalent or lower cost structure than existing PCI designs. PCI Express currently runs at 2.5Gtps, or 250MBps per lane in each direction, providing a total bandwidth of 16GBps in a 32-lane configuration. AnandTech is taking a look at the possible benefits here.
