# NVIDIA unveils the Blackwell GPU platform

At GTC 2024, NVIDIA introduced the Blackwell architecture (B200, GB200 NVL72 rack), a dual-die GPU designed for trillion-parameter model training and inference, succeeding Hopper.

## Key facts
- Announced 18 March 2024 at GTC
- 208 billion transistors across two dies
- GB200 NVL72 rack connects 72 Blackwell GPUs via NVLink
- Volume shipments ramped from late 2024 into 2025

## What happened

NVIDIA announced its next-generation AI accelerator and rack-scale systems, with all major clouds as launch customers.

## Why it matters

Blackwell racks became the building block of 2025's gigawatt-scale AI datacenters.
