Cisco Unveils AI‑Optimized Silicon One G300 Chip and Router to Compete in $600 B AI Infrastructure Market

February 10, 2026

Cisco announced the launch of its Silicon One G300 AI‑optimized networking chip and the accompanying Cisco N9000 and 8000 router systems. The new chip powers the next‑generation Cisco routers, delivering a 102.4 terabits per second switching capacity and a 28% improvement in AI job completion time compared with previous models. The design incorporates liquid cooling and high‑density optics, and its programmable architecture allows future upgrades without replacing hardware.

The launch positions Cisco against Broadcom and Nvidia in the $600 billion AI infrastructure spending boom. Cisco’s shift from legacy networking to high‑margin AI infrastructure is driven by strong demand from hyperscalers, which placed $1.3 billion of AI orders in the first quarter of fiscal 2026. Management expects the AI infrastructure segment to generate roughly $3 billion in revenue in 2026, supporting a raised full‑year revenue outlook of $60.2 billion to $61.0 billion.

Cisco’s first quarter of fiscal 2026 delivered $14.9 billion in revenue, up 8% year‑over‑year, and a non‑GAAP EPS of $1.00, a beat that reflected disciplined cost control and a favorable mix of high‑margin AI networking contracts. The company’s guidance for the second quarter of fiscal 2026 calls for revenue of $15.11 billion to $15.12 billion and EPS of $0.94 to $1.02, indicating confidence in continued demand and margin maintenance.

Jeetu Patel, Cisco’s president and chief product officer, said the new silicon platform “builds the foundation for the future of infrastructure, supporting every type of customer—from hyperscalers to enterprises—as they shift to AI‑powered workloads.” CEO Chuck Robbins added that the AI transition is “the largest AI transition it has ever seen,” underscoring the company’s strategic focus on high‑margin AI solutions.

Investors reacted cautiously to the announcement, waiting for the company’s earnings release the following day. Analysts noted that the muted market response reflected the focus on the upcoming Q2 earnings, where Cisco’s strong beat and raised guidance are expected to provide the most immediate insight into the company’s financial trajectory.
