Graphics Processing Unit (GPU)
A high-performance processor designed to handle many calculations simultaneously (images, videos, AI, 3D graphics).
Why it exists
Originally built for video games → now core to AI, ML, scientific computing, data centres.
CPU vs GPU
• CPU → Few complex tasks (sequential)
• GPU → Thousands of small tasks (parallel computing)
→ Ideal for AI & graphics
How it works
• Breaks big tasks into thousands of tiny tasks
• Many cores process simultaneously
• Enables fast neural network training & rendering
Why GPUs matter today
• AI needs massive data processing
• Efficient for matrix/tensor operations
• Essential for modern AI infrastructure (Nvidia dominance)
