Nvidia's networking business reached a $60 billion annualized run rate in fiscal Q1, nearly matching Cisco's total company revenue and surpassing Arista Networks.

Nvidia disclosed that fiscal Q1 networking revenue reached $15 billion, tripling year over year, which annualizes to a $60 billion run rate. This includes AI networking, InfiniBand, and Spectrum-X offerings.

The company's Mellanox acquisition in 2020 gave Nvidia control of InfiniBand networking technology designed to move data between GPUs with minimal latency. Nvidia's Spectrum-X Ethernet platform now competes directly against Broadcom and Cisco while integrating tightly with Nvidia GPUs and software.

Nvidia's networking revenue now approaches Cisco's entire trailing 12-month company revenue of $60.7 billion and far surpasses Arista Networks' $9.7 billion, positioning Nvidia as a full-stack AI infrastructure provider competing across networking, cloud infrastructure, AI software, and integrated systems rather than as a single-category GPU business.
