What is a GPU?
A GPU (Graphics Processing Unit) is a specialized computer chip originally designed to quickly create images and videos for your screen.
Unlike a CPU (Central Processing Unit) which handles all kinds of tasks, a GPU is specifically built to perform many simple calculations at the same time, which makes it perfect for graphics and certain types of specialized computing.
Simple Analogy
Think about the difference between a CPU and GPU like this:
- CPU: A brilliant mathematician who can solve complex problems one at a time, very quickly
- GPU: A huge classroom of students who can each solve simple math problems in parallel
If you need to solve one complicated equation, you’d ask the mathematician (CPU). But if you need to solve thousands of simple equations, the classroom (GPU) will finish much faster by working on many problems simultaneously.
How GPUs Work
GPUs are designed with:
- Many Cores: Thousands of small processing units (compared to a few powerful cores in CPUs)
- Parallel Architecture: Designed to do many calculations at the same time
- Specialized Memory: High-bandwidth memory optimized for graphics and data processing
- Specific Instruction Sets: Optimized for mathematical operations common in graphics and AI
