Cisco Announces New AI Network Chip, Challenging Broadcom and NVIDIA

As of February 2026, interest in AI infrastructure is expanding beyond "Compute" to include "Connect." In this context, the network silicon "Silicon One G300" and related new systems announced by Cisco Systems at Cisco Live EMEA are positioned as an initiative focused on the requirements prioritized during the expansion phase of AI data centers (bandwidth, operability, and power efficiency). The G300 boasts switching performance for large-scale AI clusters and, in conjunction with updates to the new N9000/8000 series, liquid cooling designs, optical modules, and operational management (Nexus One), aims to increase the effective utilization of GPU investments.
