Engineering Architecture Brief

NVIDIA ConnectX NICs and SuperNICs are advanced intelligent network adapters designed to accelerate AI factories, cloud infrastructure, enterprise networking, and high-performance computing environments. Featuring hardware acceleration for RDMA, GPUDirect, in-network computing, and storage protocols, the ConnectX family minimizes CPU overhead while maximizing throughput and efficiency. Supporting both Ethernet and InfiniBand fabrics, these adapters provide scalable connectivity, ultra-low latency, and secure high-speed communication for next-generation AI and data center workloads. Modern ConnectX SuperNICs support PCIe Gen6 connectivity and deliver up to 1.6 Tb/s aggregate throughput for hyperscale GPU clusters.
