Cisco Silicon One

Experience the power of a unified silicon architecture

Enable convergence without compromise and redefine AI/ML networking—all with one silicon architecture.

Overview Resources

Breakthrough innovation in performance, flexibility, and sustainability

Cisco Silicon One is the only unifying architecture that delivers the highest bandwidth routing and web scale switching silicon in the industry.

Get performance at scale

Meet demands for scale with a choice of a high-performance, feature-rich, and low-power networking silicon—that provides a consistent experience across the entire Cisco Silicon One portfolio.

Protect your investment

Evolve your AI/ML infrastructure with programmability while still providing low latency, cost, and power. 

Boost sustainability

Significantly reduce costs, power, and latency of network deployments with fewer network layers. That means a more sustainable network with fewer devices that last longer and are more efficient.

Manage and secure your network

Get end-to-end visibility, so you can see everything and respond when needed—with advanced trustworthy telemetry capabilities.


Cisco Silicon One devices

From top-of-rack (ToR) switches, web scale data centers and across service providers, to enterprise networks and data centers with a fully unified routing and switching portfolio, our devices power Cisco and third-party systems.

Redefine your AI/ML networks

Cisco Silicon One is helping the industry meet rapid large-scale buildouts of AI/ML that networks of the past were unable to handle. Power your AI/ML networks and configure the network to deploy standard Ethernet, enhanced Ethernet, or scheduled Ethernet to achieve best-in-class characteristics for each use case.

One architecture. One experience.

Faster innovation. Simplified operations. Unmatched capabilities. All by building with one unified silicon architecture.
