The PEX8749 architecture supports packet cut-thru with a maximum latency of 126ns (x16 to x16). This, combined with large packet memory,
flexible common buffer/FC credit pool and non-blocking internal switch architecture, provides full line rate on all ports for performance-hungry
applications such as servers and switch fabrics. The low latency enables applications to achieve high throughput and performance. In addition to low
latency, the device supports a packet payload size of up to 2048 bytes, enabling the user to achieve even higher throughput.
