Chips Part 6: What is a GPU? Thousands of small cores
// WHAT YOU WILL LEARN
A GPU has thousands of small, simple cores that work on many pixels at once, so it draws games and video far faster than a few big CPU cores.
// LESSON NOTES
What makes your games so smooth? 🎮⚡
🧠 A CPU has a few big, clever cores — great at one hard job at a time.
🐢 Painting a whole screen one pixel at a time? Far too slow.
🟩 A GPU has thousands of small, simple cores — each paints its own pixels, all at once!
📱 A 1080 × 2400 phone screen = about 2.6 million pixels, redrawn 60 times a second.
🎬 That's why games, video and AI all run on GPUs.
