HPE NVIDIA H100 SXM5 80GB GPU for HPE Cray EX

The HPE NVIDIA H100 SXM5 80GB GPU for HPE Cray EX (P53862-B21) is a flagship accelerator built on NVIDIA's Hopper architecture, purpose-engineered for the demanding computational requirements of large-scale AI training, scientific simulation, and high-performance computing. The H100 SXM5 leverages the SXM5 board form factor to deliver full NVLink 4.0 interconnect bandwidth between GPUs within a node, enabling tightly coupled multi-GPU configurations that are essential for training and inferencing foundation models and transformer-based neural networks at scale.

With 80GB of HBM3 high-bandwidth memory and a memory bandwidth of approximately 3.35 TB/s, this accelerator is optimized for memory-intensive workloads that require rapid movement of large datasets and model weights. The Hopper architecture introduces the fourth-generation Tensor Core with support for FP8 precision, significantly expanding throughput for AI inference alongside FP16, BF16, TF32, FP64, and INT8 compute modes. The Transformer Engine, a key Hopper innovation, dynamically selects precision per layer to maximize throughput without sacrificing model accuracy.

Designed exclusively for integration within HPE Cray EX supercomputing and enterprise AI systems, the P53862-B21 is qualified and supported under the HPE portfolio to ensure compatibility with HPE Cray EX blade and chassis infrastructure. This tight hardware-software co-design enables enterprises and research institutions to deploy petascale AI and HPC environments with confidence, backed by HPE's system-level engineering, thermal management, and firmware integration for the Cray EX platform.
