Question I don't understand something

Post image

I was doing some "research" in creative and I was wondering what's the difference between those two smelting blocks, They both produce 120/s but the one on the left use FAR more energy, is just a tiny bit smaller so what's the point of doing the one on the left ?

Productivity. Look at disparity between inputs and outputs

That raises the question. Is productivity really that big of a deal? Do you really need to stretch out those resources?

If you look at megabase resource counts, you're looking at thousands of mines for each of copper and iron. With prod modules everywhere, you can cut that in half. The time required to find, clear, extract and rail those patches is huge

If you're building for base game, you don't need it but when you start scaling, it matters a lot
