The Intel 82571 Gigabit Ethernet Controller for PCI Express is designed for high performance and low memory latency. The device is optimized to connect to a system Memory Control Hub (MCH) using up to four PCI Express lanes. Altertively, the controller can connect to an Input/Output (I/O) Control Hub (ICH) that has a PCI Express interface. Wide interl data paths elimite performance bottlenecks by efficiently handling large address and data words. Combining a parallel and pipelined logic architecture optimized for Gigabit Ethernet and for independent transmit and receive queues, the controller efficiently handles packets with minimum latency.
The Intel 82571 Gigabit Ethernet Controller is a single, compact component with two fully integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) ports
