Cisco Silicon One

Meet the first unified silicon architecture for web scale and service provider networks.

Breakthrough innovation to power the Internet for the Future

Innovations guided by 35 years experience building the world’s most complex networks powered by silicon that carries over 90 percent of IP traffic.

We challenged every assumption of how networking silicon is built to deliver the performance and efficiency of switching silicon with the scale, buffering, programmability, and carrier-class features of routing silicon.

One processor. No compromises.

Cisco Silicon One™ Q100 is the industry’s first routing silicon to break 10 Tbps with a single ASIC.

2x more the bandwidth

More network bandwidth in a single ASIC than any other routing silicon.

Global routing scale

Ready for massive Internet scale.

3x more performance

More packets per second than any other programmable silicon.

Deep buffering

Protecting against packet loss across congested links.


P4 programmable for faster feature delivery and future ready deployments.

2x more power efficient

Routing features, scale and performance at switching efficiency.

Unified architecture

Cisco Silicon One delivers consistency in features, services, and telemetry across:


  • Service provider
  • Web scale provider

Form factors

  • Fixed
  • Modular


  • Full-featured line card network processor
  • Fabric element in a modular router
  • Full-featured router on a chip

Cisco Silicon One revolutionizes network innovation

Network engineers can spend more time innovating the network and less time tuning the network. With a unified silicon architecture, network engineers can plan, qualify, and deploy network architecture more rapidly and simply without having to worry about the compatibility of different systems based on distinct silicon architectures for each network function.

The future is now

The first routing chip introduced from this architecture, the Cisco Silicon One Q100 delivers 108x100 GE to power the Cisco 8200 Series routers for a full-featured 10.8 Tbps carrier-class router in 1RU. The Cisco Silicon One Q100 also powers the modular 8800 Series routers which deliver up to 260 Tbps.
