System Interface
The 82574 provides one PCIe lane operating at 2.5 GHz with sufficient bandwidth to
support 1000 Mb/s transfer rate. 40 KB of on-chip buffering mitigates instantaneous
receive bandwidth demands and eliminates transmit under–runs by buffering the entire
outgoing packet prior to transmission.
Features Summary
This section describes the 82574’s features that were present in previous Intel client
GbE controllers and those features that are new to the 82574.
