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. Alternatively, the controller can connect to an Input/Output (I/O) Control Hub (ICH) that has a PCI Express interface. Wide internal data paths eliminate 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
