New G300-powered Cisco N9000 and 8000 systems, advanced optics and management upgrades deliver hyperscale-level performance, reliability and efficiency for all AI network builders. News Summary:
AMSTERDAM, Feb. 10, 2026 /PRNewswire/ -- CISCO LIVE EMEA -- Cisco (NASDAQ: CSCO) continues to transform the network into an AI innovation platform, today unveiling the Silicon One G300, a 102.4 Tbps switching silicon designed for massive AI cluster buildouts. The Cisco Silicon One G300 will power new Cisco N9000 and Cisco 8000 systems that push the frontier of AI networking in the data center. The systems feature innovative liquid cooling and support high-density optics to achieve new efficiency benchmarks and ensure customers get the most out of their GPU investments. In addition, the company enhanced Nexus One to make it easier for enterprises to operate their AI networks — on-premises or in the cloud — removing the complexity that can hold organizations back from scaling AI data centers.  "We are spearheading performance, manageability, and security in AI networking by innovating across the full stack - from silicon to systems and software," said Jeetu Patel, President and Chief Product Officer, Cisco. "We're building the foundation for the future of infrastructure, supporting every type of customer—from hyperscalers to enterprises—as they shift to AI-powered workloads." "As AI training and inference continues to scale, data movement is the key to efficient AI compute; the network becomes part of the compute itself. It's not just about faster GPUs – the network must deliver scalable bandwidth and reliable, congestion-free data movement," said Martin Lund, Executive Vice President of Cisco's Common Hardware Group. "Cisco Silicon One G300, powering our new Cisco N9000 and Cisco 8000 systems, delivers high-performance, programmable, and deterministic networking – enabling every customer to fully utilize their compute and scale AI securely and reliably in production." Silicon One G300: The Networking Foundation for the Agentic Era The G300 uniquely offers Intelligent Collective Networking, which combines an industry-leading fully shared packet buffer, path-based load balancing, and proactive network telemetry to offer better performance and profitability for large-scale data centers. It efficiently absorbs bursty AI traffic, responds faster to link failures, and prevents packet drops that can stall jobs, ensuring reliable data delivery even over long distances. With Intelligent Collective Networking, Cisco can deliver 33% increased network utilization, and a 28% reduction in job completion time versus simulated non-optimized path selection, making AI data centers more profitable with more tokens generated per GPU-hour. Cisco Silicon One G300 is highly programmable, enabling equipment to be upgraded for new network functionality even after it has been deployed. This enables Silicon One-based products to support emerging use cases and play multiple network roles, protecting long-term infrastructure investments. And with security fused into the hardware, customers can embrace holistic, at-speed security to keep clusters up and running. Cisco Silicon One is the industry's most scalable and programmable unified networking architecture, offering a complete portfolio of networking devices across AI, hyperscaler, data center, enterprise, and service provider use cases. Introduced in 2019, Cisco Silicon One is playing critical roles in major networks around the world. New Systems, Optics: High-Density, Scalable Design for Power-Efficiency and Performance
