ToggleCisco Takes on Broadcom and Nvidia With New AI-Focused Networking Chip
In a major move to capture a share of the booming AI infrastructure market, Cisco Systems has launched a new, high-performance AI-optimized networking chip. The Silicon One G300 and its accompanying routers are designed to accelerate data traffic inside massive AI data centers, setting up a direct clash with rivals Broadcom and Nvidia.
Announced on February 10, 2026, the G300 chip represents Cisco’s strategic push into the core of AI hardware, a market estimated at roughly $600 billion. As AI models grow, the need to swiftly move vast amounts of data between thousands of GPUs has made networking a critical bottleneck—a challenge Cisco’s latest innovation aims to solve.
From Compute to Connectivity: Networking Becomes Key to AI
The AI hardware race has long focused on GPU power and AI accelerators. However, the efficiency of the network connecting these processors is now a first-order priority for system performance. Cisco’s launch underscores this shift, positioning high-performance networking as essential, not incidental, to the AI compute stack.
Fabricated on TSMC’s advanced 3-nanometer process, the G300 promises high density and energy efficiency. Slated for commercial availability in the second half of 2026, it will power Cisco’s next-generation routers and switches.
A key innovation is Cisco’s proprietary network-optimization technology, acting as intelligent “shock absorbers.” This system can dynamically reroute traffic in microseconds around congestion or failures, maintaining smooth data flow across complex AI clusters. Cisco estimates this could accelerate some AI computing tasks by up to 28% by minimizing network delays.
Cisco Enters a Competitive Arena Against Established Rivals
Cisco’s challenge comes as both Broadcom and Nvidia aggressively expand their networking footprints for AI.
Broadcom’s Tomahawk series switches are entrenched in hyperscale data centers.
Nvidia leverages its GPU dominance to offer tightly integrated computing and networking stacks, including its own custom networking chips.
While Cisco’s heritage is in enterprise networking, its significant R&D investment in AI-optimized products reflects a strategic pivot. The company is targeting customers moving from basic connectivity to performance-tuned environments for AI training and inference workloads.
A Full Ecosystem for the “Agentic Era” of AI
Beyond the chip, Cisco is introducing enhanced systems in its N9000 and 8000 series to leverage the G300. These feature both air-cooled and 100% liquid-cooled designs for greater energy efficiency—a critical factor for hyperscale operators.
The company is also rolling out advanced optical modules and unified management software designed to simplify operations, improve reliability, and reduce costs for large-scale AI deployments. Cisco positions this entire platform as foundational for the coming “agentic era” of autonomous, real-time AI systems.

Industry Implications: The AI Infrastructure War Expands
The launch of the Silicon One G300 signals that the AI infrastructure competition is broadening beyond compute into networking and system integration. By tackling a core scalability bottleneck, Cisco is claiming a vital part of the technology stack that will heavily influence the cost and performance of future AI.
As data centers evolve to support larger, more distributed AI workloads, the battle between Cisco, Nvidia, and Broadcom will have significant implications for the economics and capabilities of next-generation artificial intelligence.
