Compare Circuit Switching And Packet Switching. Circuit switched noc has, compared to packet switching, a longer setup time, guaranteed throughput and latency, higher clock frequency, lower hw complexity, and higher energy efficiency. The following table highlights the major differences between circuit switching and packet switching −.

Packet switching and circuit switching are different methods of routing data from one destination to another. On the other hand, packet switching is a method of grouping data that is transmitted over a digital network into packets. A dedicated path has to be established between the source and the destination before transfer of data commences.
