Graphics Processing Unit (GPU)
A graphics processing unit is a processor with thousands of small cores designed for parallel calculations, now the main hardware used to train and run AI models.
What is Graphics Processing Unit (GPU)?
Originally built for video games, GPUs suit the matrix arithmetic of neural networks. High-end data-centre GPUs, led by Nvidia, are a strategic resource subject to export controls.
How it works
Large training runs link thousands of GPUs with high-speed networks so they work on one model together.
