NVIDIA H100 SXM

The GPU that launched the AI era — 80GB HBM3, 3.35 TB/s bandwidth, 3,958 TFLOPS FP8, NVLink 900 GB/s in an SXM form factor for HGX and DGX systems.

Description

Overview

The NVIDIA H100 SXM is the GPU that ignited the generative AI revolution. Built on the NVIDIA Hopper architecture, it delivers 3,958 TFLOPS of FP8 Tensor Core performance with 80GB of HBM3 memory at 3.35 TB/s bandwidth. As the compute engine behind DGX H100 and HGX H100 systems, it remains one of the most widely deployed data center GPUs for AI training and inference at scale.

The H100 introduced the Transformer Engine with FP8 precision support, Multi-Instance GPU (MIG) technology for up to 7 isolated GPU instances, and fourth-generation NVLink at 900 GB/s — setting the foundation for modern AI infrastructure.
