NVIDIA H100 PCIe 80GB – Hopper Tensor Core Data Center GPU

Description

The NVIDIA H100 PCIe 80GB is a purpose-built accelerator for demanding enterprise AI and high-performance computing environments. Based on the NVIDIA Hopper architecture, the H100 combines fourth-generation Tensor Cores, CUDA acceleration, high-bandwidth HBM2e memory, and PCIe Gen5 connectivity to provide substantial computational throughput for modern AI and HPC workloads.

The PCIe model provides 80GB of HBM2e GPU memory across a 5,120-bit memory interface, with a specified peak memory bandwidth of approximately 2,000 GB/s (2TB/s). This large, high-bandwidth memory subsystem is particularly valuable for large neural-network models, scientific simulations, large-scale data processing, and workloads that require rapid movement of datasets between compute resources and GPU memory.

The GPU provides 14,592 CUDA cores and 456 fourth-generation Tensor Cores. NVIDIA specifies up to 51 TFLOPS FP32, 756 TFLOPS TF32 Tensor Core performance, and 1,513 TFLOPS BF16/FP16 Tensor Core performance with sparsity for the PCIe variant.

Connectivity is provided through a PCI Express Gen5 x16 interface, with up to 128GB/s aggregate PCIe bandwidth. The platform also supports NVIDIA NVLink connectivity for supported multi-GPU configurations, while the H100 PCIe is designed as a dual-slot, air-cooled accelerator suitable for compatible data-center servers.

The H100 PCIe supports Multi-Instance GPU (MIG) technology, allowing the physical GPU to be partitioned into multiple isolated GPU instances. NVIDIA documents configurations of up to seven MIG instances, including profiles with up to 80GB of total framebuffer available to a single instance.

The accelerator also supports SR-IOV, enabling virtualization-oriented deployment scenarios, and NVIDIA documents Linux and Windows driver support for the H100 PCIe platform.

5. Compatibility

The H100 PCIe 80GB is intended for compatible enterprise servers and data-center systems equipped with PCIe Gen5-capable expansion slots and adequate power and cooling.

NVIDIA identifies the PCIe H100 as a dual-slot, air-cooled PCIe accelerator and lists deployment in partner and NVIDIA-Certified systems supporting configurations from one to eight GPUs.

Before installation, the host server should be checked for:

PCIe Gen5 x16 or compatible PCIe slot configuration
Two-slot GPU clearance
Adequate airflow
Appropriate auxiliary GPU power connection
Sufficient power-supply capacity
BIOS/UEFI support
NVIDIA H100-compatible drivers
Server manufacturer’s GPU support list
Appropriate chassis thermal design

Important: The H100 PCIe 80GB is a data-center accelerator, not a conventional consumer graphics card. It does not target desktop gaming use and is designed primarily for server-based compute workloads.
