NVIDIA ConnectX-8 SuperNIC 800GbE PCIe Gen5 Dual-Port OSFP

The NVIDIA ConnectX-8 SuperNIC is a dual-port 800GbE network adapter engineered for next-generation AI infrastructure built on NVIDIA Blackwell GPUs. Each port delivers 800Gb/s of bandwidth over PCIe Gen5, enabling ultra-low latency GPU-to-GPU communication across scale-out enterprise AI clusters. The adapter integrates NVIDIA BlueField data processing capabilities, offloading networking, security, and telemetry workloads from the CPU to reduce system overhead and maximize AI model training throughput.

Designed for high-density GPU server environments, the ConnectX-8 SuperNIC supports advanced clustering protocols, congestion management, and in-network computing to eliminate network bottlenecks in large-scale distributed training. The OSFP connector format enables compact deployment in modern data center architectures while maintaining full compatibility with NVIDIA's software ecosystem.

This adapter targets enterprises deploying multi-GPU clusters for large language model (LLM) training, generative AI workloads, and high-performance computing (HPC) applications where inter-GPU communication latency directly impacts model convergence time and training efficiency.

Ideal for

• Multi-node GPU cluster training for large language models and foundational AI models requiring sub-microsecond inter-GPU communication
