NVIDIA Quantum-X800 Infiniband Switch Front View

Powering Next-Gen AI Performance

NVIDIA Quantum-X800 InfiniBand switches deliver 800Gb/s throughput with ultra-low latency, ideal for trillion-parameter-scale generative AI. Featuring advanced In-Network Computing, RDMA, SHARP, and adaptive routing, these switches boost performance across high-performance computing and AI data centers.

Scalable Platform for AI and HPC

Built to meet the increasing bandwidth needs of HPC, AI, and hyperscale cloud environments, Quantum-X800 features a dedicated in-band management port for efficient UFM access and a front panel layout that simplifies connectivity and topology planning.

Unmatched Scalability and Performance

Quantum-X800 enables 2X faster speeds and 5X greater scalability. A two-tier fat-tree topology supports over 10,000 host connections at 800Gb/s. SHARPv4 provides efficient compute offloading, including FP8 support and new collective operations like ReduceScatter and ScatterGather.

Bandwidth Efficiency and Traffic Control

With telemetry-based congestion control and enhanced adaptive routing, the Quantum-X800 ensures near-perfect bandwidth utilization and isolates workloads for optimal multi-tenant and multi-job performance.
