# NVIDIA announces the H100 'Hopper' GPU

NVIDIA unveiled the Hopper architecture and H100 GPU with a Transformer Engine and FP8 support; the H100 became the defining AI training chip of the generative AI boom.

## Key facts
- Announced at GTC on 22 March 2022
- 80 billion transistors, TSMC 4N process
- Transformer Engine with FP8 precision
- Extreme demand after ChatGPT drove NVIDIA's datacenter revenue surge in 2023–2024

## What happened

NVIDIA introduced its datacenter GPU designed explicitly around Transformer workloads.

## Why it matters

H100 supply became the key bottleneck and currency of the AI race; GPU counts became a proxy for lab ambition.
