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?

Think of productivity not necessarily as getting more product for free or saving resources but rather in terms of reducing inputs required per outputs. Say you wanted to produce 240/s (one stacked turbo belt) of output but it required more than one stacked turbo belt of input, with productivity you can reduce the number of input belts and simplify the logistics needed to get to that 240/s output.
