Why is a processor’s speed not the only important factor in a computer’s performance?

1.01K views

Hello, everyone! I’ve been doing some research into computer hardware lately, and one thing that I keep coming across is this idea that the speed of a processor, while important, isn’t the only thing that affects a computer’s overall performance. I’m having a bit of a hard time wrapping my head around this because I always thought that a faster processor meant a faster computer. Can anyone explain why this isn’t necessarily the case? I’m really interested to learn more about this!

ELI5 answer:

You’re reading a book. Because the book is with you, you’re able to read it quickly.

You finish the book and want to read another. Unfortunately you’ve run out of books and have order one to be delivered the next day.

It’s the waiting that slows everything down.

So in a computer if the super fast CPU is waiting on something slow, like a disc, then that will impact the performance.
