A GPU (Graphics Processing Unit) is a specialised processor.
It performs complex calculations very fast. ⚡

It was originally made for graphics.
It renders images and videos.
Now it is used in Artificial Intelligence (AI) and Machine Learning (ML).

A GPU works differently from a CPU.
A CPU handles tasks one by one.
A GPU handles thousands of tasks together.
This is called parallel processing.

GPUs are essential for:

• AI model training 🤖

• Big data analysis

• Climate modelling 🌍

• Defence simulations

🧠 Memory Trick

“GPU = Graphics → Parallel → Ultra-fast AI”

G = Graphics origin
P = Parallel processing
U = Ultra-fast AI applications

Remember:
CPU = Few powerful cores
GPU = Thousands of small cores

This difference is often asked in UPSC Prelims. 🎯
