Cornelis launches CN6000 800G networking to rival Nvidia InfiniBand - The Next Web

Cornelis CN6000 is not merely a product update; it is a structural challenge to Nvidia's InfiniBand monopoly. Technologically, the shift toward 800G Ethernet in AI clusters will force upstream optical module manufacturers to pivot from InfiniBand-specific chips to general-purpose Ethernet architectures, reducing BOM costs and breaking single-vendor lock-in. From a compliance perspective, this move weakens the technical barriers of US export controls on high-performance networking, offering alternative pathways for sanctioned entities while intensifying geopolitical fragmentation in the supply chain. In market dynamics, Nvidia is unlikely to cut prices; instead, it will maintain high margins by bundling the CUDA ecosystem with NVLink private protocols, while accelerating Spectrum-X iterations to defend its flank. Over the next 12-24 months, the industry will undergo a painful 'de-InfiniBand' transition. Ethernet switch chip capacity will become the new bottleneck, and hyperscalers with full-stack R&D capabilities will leverage this shift to restructure internal networks, effectively decoupling from reliance on a single hardware giant.
