NVIDIA DGX: What It Is and Why It Matters

What DGX is

DGX systems are built around NVIDIA accelerators and software.

Depending on the generation, a DGX product may combine:

DGX products are designed primarily for organizations building or operating advanced AI workloads.

Early GPU computing often meant adding accelerators to conventional servers.

As deep learning workloads became larger, the entire system architecture started to matter.

NVIDIA introduced DGX to provide a system designed around GPU-accelerated AI from the beginning.

This represented an important strategic change.

NVIDIA was no longer only supplying a component inside another company's computer. It was increasingly designing the complete computing system.

CUDA provides the programming foundation for running GPU-accelerated software.

DGX provides a physical system in which those GPU workloads can run at scale.

The two therefore occupy different layers of the NVIDIA platform:

Applications

AI frameworks and NVIDIA software

CUDA

GPU architecture such as Blackwell

DGX system
↓
Networking and data-center infrastructure

Current DGX generations can use Blackwell architecture.

This demonstrates why BizTear should maintain separate pages for an architecture and a system family.

Blackwell explains the underlying computing generation.

DGX explains the integrated product that organizations deploy.

Typical users include:

Some customers buy DGX systems directly, while others access similar NVIDIA infrastructure through cloud services.

It showed that NVIDIA wanted to control and optimize more of the computing stack rather than sell GPUs alone.
