eli5 : How does reducing cpu’s lithography help its performance? couldnt you fit more stuff into a bigger cpu?
In: Technology
The fundamental issue here is the speed of light. When you’re trying to make a cpu fast (aka clock speed) you’re limited by how long it takes for the signals to propogeate on the teeny tiny wires. The shorter the wires can be the faster the whole thing can go.
Consider a metaphor. Imagine you are employed to make sandwiches. If you had a small prep area with everything you need then you can make a sandwich quickly. But in a very large kitchen with the things spread all over you’ll have more space to out stuff but it will take a long time to fetch each ingredient and you’ll have spent a long time walking to and fro.
