H100, NVIDIA Data Center GPU with Hopper data center GPU for accelerated AI and high-performance computing

100% Genuine Ready to Ship

Vista general

NVIDIA Mellanox H100 Vista general

NVIDIA H100 is a Hopper-generation data center GPU for large-scale AI and high-performance computing. Because the H100 family includes different form factors and memory/power configurations, the PCIe, SXM or NVL variant must be confirmed before ordering.

Key Specifications

GPU Architecture

NVIDIA Hopper with Transformer Engine and second-generation Multi-Instance GPU

Memory Configuration

80GB HBM3 for H100 SXM/PCIe; H100 NVL uses a separate 94GB configuration

Memory Bandwidth

Up to 3.35 TB/s for SXM, 2 TB/s for PCIe and 3.9 TB/s for NVL

AI and HPC Performance

Up to 3,958 FP8 TFLOPS and 3,958 INT8 TOPS with sparsity for H100 SXM

MIG and Interconnect

Up to 7 MIGs and NVIDIA NVLink / PCIe Gen 5 connectivity

Power and Form Factor

Up to 700W SXM, 350W PCIe or 350–400W NVL; form factor varies by version

Best Fit Applications

Large-Scale LLM Training

Hopper Tensor Cores and Transformer Engine accelerate large model training and mixed-precision AI workloads.

Multi-GPU Inference

NVLink, PCIe Gen 5 and MIG support scalable inference, multi-tenant deployment and GPU partitioning.

Scientific Computing and HPC

High FP64, FP32 and Tensor Core throughput supports scientific simulation, analytics and high-performance computing.

Cloud and Data Center AI

The H100 platform is designed for server and data-center deployments rather than desktop graphics systems.

Why H100

Hopper Transformer Engine

The Transformer Engine and Tensor Core acceleration support high-throughput mixed-precision training and inference.

Flexible Data Center Configurations

SXM, PCIe and NVL variants support different server, interconnect, memory and power requirements.

MIG and NVLink Scale

MIG enables partitioned GPU service, while NVLink supports tightly coupled multi-GPU systems.
