GPU

A GPU, or Graphics Processing Unit, is a special kind of computer chip originally designed to make graphics look amazing in video games. Unlike a CPU (Central Processing Unit), which is like a general-purpose brain, a GPU is built to handle many calculations at the same time. Think of it like this: a CPU is a brilliant manager who can do many different tasks one after another, while a GPU is an entire team of highly skilled workers who can all do similar tasks simultaneously, making them super fast for specific jobs.

This ability to do lots of parallel calculations makes GPUs incredibly powerful for tasks beyond just graphics. In the world of AI, machine learning and deep learning models often involve tons of repetitive mathematical operations, especially when training neural networks. Because GPUs are so good at these kinds of tasks, they've become the backbone for accelerating AI development, making it possible to train complex models much faster than with traditional CPUs alone. They are essential for everything from training large language models to powering self-driving cars.
