Speed or productivity module

[Dan Niton]

So out of these 2 modules, which is more efficient? Currently I'm trying to mass produce engines for the blue science pack and have no idea if I should insert 2 speed or 2 productivity modules in each assembly machine.

Edit: Most of these post had partially answered my question but I guess I should clarify further. I do know that speed mod reduce the time it takes to make an engine while productivity makes more engine at the expense of speed. Lets exclude space for the time being.

What I wanted efficiency wise in my case is getting the most possible number of engines in the shortest possible time. Should I go:
1. speed+productivity mod?
2. speed+speed? or
3. productivity+productivity?

Assuming that all engines are going into the wooden storage, which of these 3 will fill up the storage the fastest?

Speed in beacons, productivity in everything else (maybe not miners), ignore efficiency modules.

Miners consume more power than anything else in the game. I usually use one of each module in miners once I have modules at level 3.

Power is not really a problem in lategame. Miners are also just a minor power sink compared to beacons. It depends on your base layout but in my 20 GW base, beacons need 10 GW, assemblers 4 GW, furnaces 3 GW and miners not even 0.2 GW.

I know that many people argue that the pollution is lower when you use efficiency modules! But lets be honest, pollution is not really a thing you have worry about when you unlock lasers.

Why does everyone always talk about things from the 'lategame' perspective?

Yeah, you can generate almost limitless power quite easily in this game, but you still need to reach it.
I've been throwing Mk I Efficiency modules into almost everything (Miners, furnaces, most assemblers) to keep power down to a minimum because I'm refusing to use solar power this game.
It gets stupid when your solar fields are several times the size of your base and I've only found one small patch of Uranium so far.

You need a maximum of maybe 500 MW to reach a point where you can just put down nuclear plants. And to get to this point you copy and paste the same normal power plant und fuel it with coal or solid fuel from oil. I don´t see the problem.

"The problem" is that nobody really struggles in the late game.
At that point you can pretty much do what you want, sure some approaches are better then others, but there is no way to really mess ♥♥♥♥ up anymore.

Meanwhile modules can be produced pretty early in the game. In the midgame the right choice of modules can make or break the factory, stopping or supercharging further progress.

For me, it's simply productivity module. Why? Because you can use speed module on beacons. :)

And oh, when you use speed module, your resources needed per second will increase. Whilst productivity module will reduce your resources needed (slower speed) and adding output.

If you use too much speed module, you will need to expand more and more.

[Hedning]

For base efficiency focus on both at the same time, because they are both very expensive, so you want to speed boost the machines with productivity modules. As high level as possible and start at the top machines and go down, ie start with the science labs, then yellow and purple science assemblers, then blue circuits, and so on. Don't build prod 1 modules and put them in furnaces. Take them out of the furnaces, combine them to tier 2 and put them in your labs.

To elaborate:
Lets say you only focused on speed, then you save almost nothing in terms of resources. Science labs are dirt cheap, so instead of building expensive modules you could just build more labs. There are some cases where it's useful though: say you built 1 gear assmebler directly feeding your blue underground assembler and building a second would require some effort in redesigning that area, then put some speed modules in it.

Lets say you instead only focused on productivity modules, well that's better. By placing two level 3 productivity modules in your labs you have effectively increased pretty much your entire factory by 20%. That's massive. Just from placing modules in your labs. However because they are slow you now need lots of labs and all of them will need expensive productivity modules to gain the bonus.

Lets look at the combination then. With 2 productivity 3 modules their crafting speed is 70%. With 1 beacon this becomes 120% This means you will need about 60% as many labs with productivity modules if you have a beacon with speed, but it's even better, because each beacon can reach 8 labs and each lab can be reached by 8 beacons if placed in rows. It's the same for assemblers.

This mixing of speed and productivity really helps reduce how many modules you need to build. The cost is power, but compared to the cost of producing these modules it is well worth it.

Its very difficult to put beacons around electric mining drills....

Putting any of those modules in a mining drill is a very late game thing. At that point you have sent many rockets and built up your mining productivity through research. I don't think mentioning mining drills is relevant to this discussion.

I rarely use speed modules for drill. As there is infinity research number to increase drill speed.

The infinite research is mining productivity, not speed.

The only reason I use speed mods is with express belts. Stack that with production mining research and you get thicc amounts of ore

That's why I would recommend to only use speed modules for mining drills for a megafactory.

In my first megafactory I used one productivty module and two speed modules per drill - I thought that would be a great compromise. I quickly saw that the extra productivity from the endless tech dwarfes the single productivty module. The module gives you +10%, from the tech you can end up with more than +100% very quickly.

Having three speed modules in one drill on the other hand means you need a lot less drills and lot less ore patches, keeping your base far more compact resp. needing far less outposts.

Aw yiss. My comment have been replied by KoS. One bucket list achieved. Thanks for the correction anyway.

space is infinite, they said. yours bots will be fine, they said.
and speed modules will use far less power than productivity modules because you need 4x the machines to get the same output
