Hardware Architecture
The NVIDIA HGX B300 is a dense compute platform designed for massive parallel workloads. It gives modern AI teams a solid foundation for model training and inference.
Dense, purpose-built compute for the demanding frontier AI models your team is bringing to production.
A massive shared memory pool for larger model weights and expanded context without fragmentation.
Keep Blackwell cores fed with bandwidth designed for exceptionally demanding data movement.
Up to 14.4 TB/s total bandwidth behaving as one cohesive accelerator.
Fabric & interconnect
Distributed AI depends on moving data between accelerators without turning the network into the bottleneck. Cirrascale pairs HGX B300 with high-bandwidth scale-out infrastructure.
Eight NVIDIA ConnectX®-8 SuperNICs per baseboard, up to 115.2 Tb/s in total.
NVIDIA Scalable Hierarchical Aggregation and
Reduction Protocol (SHARP)™ v4 accelerates collective operations directly in switch silicon.
The fabric is designed as a first-class part of every multi-node AI system.
AI Innovation Cloud
