How do graphics cards work?

In: Technology

Answer 1

I’ll add that graphics cards exist as a separate part of the computer dedicated to graphics because they’re really really good at doing a ton of the same calculation at the same time. CPUs are fast but typically can do maybe 16 operations at once, while a GPU can do maybe 1600. This is great for graphics, where you often need to do the same calculation many times. It’s less good for general computer operations, where every operation might be different.
