Nvidia tops Ethernet data center switch charts by revenue as sales soar - SDxCentral

Nvidia has emerged as the top revenue vendor in the data center Ethernet switching market for Q1 2026, capturing 21.5% of the segment with $2.1 billion in sales, up 192.7% YoY. The company's Spectrum-... Read original →

Nvidia’s rise to the top of data center Ethernet switch revenue signals a tectonic shift from compute-centric to network-defined AI infrastructure. Its Spectrum-X platform is accelerating 800G Ethernet adoption in AI training clusters, pressuring optical vendors to fast-track co-packaged optics (CPO) and eroding InfiniBand’s dominance in hyperscale deployments. On the compliance front, U.S. export controls on advanced chips now indirectly constrain networking gear, forcing Nvidia to reconfigure its supply chain—particularly around manufacturing and packaging in Taiwan, China and Hong Kong, China. Rivals like Cisco and Arista will likely deepen alliances with AMD or Intel to promote open, disaggregated architectures against Nvidia’s vertically integrated stack, while Broadcom may leverage custom ASICs to embed into cloud-native interconnect protocols. Over the next 12–24 months, Ethernet will dominate AI data centers, but power and latency constraints will spur heterogeneous interconnect standards; without sustained protocol-layer innovation, Nvidia’s hardware premium could erode.
