Cisco unveiled its most powerful routing silicon to date in an update to the company’s growing Silicon One portfolio. The company’s 11th chip, the P100, is capable of 19.2 Tb/s of full-duplex traffic at port speeds up to 1.6 Tb/s.

The chip is able to achieve this throughput thanks to a combination of technologies, including 112 Gb/s serializer/deserializers (SerDes), Cisco’s second-generation P4 run-to-completion engine, and large tables and deep buffers.

allows the P100 to scale to a variety of form factors and service providers and hyperscale routing applications, ranging from traditional rack-mounted routers to large multi-petabit disaggregated routers.

For example, a single P100 can power a router with 24, 800 Gb/s interfaces at full speed, something Cisco claims would require six of its competitors’ chips to achieve.

For higher capacities, multiple P100 chips can be combined. Using three P100s, Cisco’s Silicon One customers could offer a line card with 28.8 Tb/s of throughput, or the equivalent to 36, 800 Gb/s interfaces.
