Satisfactory is a first-person factory builder on Unreal Engine that starts light and grows heavy as your sprawling automated factories expand across the map. Late-game mega-factories load the CPU and memory hard while UE5’s visuals lean on the GPU, so a balanced build with a strong processor and plenty of RAM keeps a giant base running smoothly.

Why big factories change the requirements
Early on Satisfactory runs well on modest hardware, but as your factory grows to thousands of machines, belts and pipes, the CPU has to simulate all of it while the GPU renders the increasingly complex world. That combination turns a light game into a demanding one, particularly in dense industrial areas.
A modern 8-core CPU handles the simulation of a large factory, 32GB of RAM copes with big saves and long sessions, and a 70-class GPU covers UE5 visuals at 1440p. Fast storage keeps the large world loading and saving quickly.
Recommended build tiers
Plan for the late game: a strong CPU and 32GB of RAM for the factory simulation, plus a GPU sized to your resolution.
| Budget band | CPU | GPU | RAM | Target performance |
|---|---|---|---|---|
| $950-1,200 | Modern 6-core | Current 60-class, 8GB+ | 16GB DDR5-6000 | 1080p early to mid factories |
| $1,350-1,650 | Modern 8-core | Current 70-class, 12GB | 32GB DDR5-6000 | 1440p large factories, high settings |
| $2,000+ | High-end 8-core | Current 70/80-class, 12GB+ | 32GB DDR5-6000 | 1440p/4K mega-factories smooth |
Starter factory rig
A modern 6-core, 16GB of RAM and a 60-class card run early and mid factories at 1080p smoothly. At $950 to $1,200 it is a fair start, though a growing base will want more CPU and memory later.
Large-factory rig
A modern 8-core with 32GB of RAM and a 70-class 12GB GPU keeps large factories smooth at 1440p. The stronger CPU and extra memory are what handle a base that sprawls across the map.
Mega-factory rig
For enormous end-game factories, a high-end 8-core and 32GB of RAM hold the simulation together at 1440p or 4K. The GPU handles the UE5 visuals while the CPU carries the machine-heavy logistics.
Where to spend and where to save
Spend on a strong CPU and 32GB of RAM, because a late-game mega-factory’s simulation of thousands of machines and belts is what loads the processor and memory. Those parts are what keep a sprawling base smooth long after the early game has passed.
Save on the GPU with a mid-range card sized to your resolution, since UE5 visuals are handled well without a flagship and the real load is the factory simulation. Put spare budget into memory and a fast SSD to avoid the stutter and slow saves that big bases otherwise cause.
Keeping a giant base smooth
If a large factory starts to stutter, the CPU and memory simulating all those machines are usually the cause, not the graphics card. Lowering render settings helps frame rate somewhat, but the simulation load scales with factory size.
Give the game 32GB of RAM to avoid stutter and slow saves in big bases, keep it on an SSD, and enable an upscaler if you want extra frames in dense industrial zones. A strong CPU is the most impactful upgrade for late-game Satisfactory.
Frequently asked questions
Does Satisfactory need a lot of RAM?
16GB is fine early, but 32GB is recommended once your factory grows large, since big saves and long sessions consume more memory and the extra headroom prevents stutter and slow saves.
Is Satisfactory CPU or GPU heavy?
It becomes CPU heavy as your factory grows, since all the machines are simulated. The GPU handles the UE5 visuals, so a balanced build with a strong CPU and mid-range GPU serves it best.
Does Satisfactory get harder to run over time?
Yes. As your factory grows to thousands of machines, the CPU and memory load climbs steeply. A strong processor and 32GB of RAM keep a late-game mega-factory smooth where early-game hardware would struggle.
Bottom line
For Satisfactory, build for the mega-factory endgame: a modern 8-core CPU, 32GB of DDR5, a 70-class GPU for your resolution and a fast SSD. That machine keeps a sprawling automated base smooth long after the game has grown from a light builder into a demanding simulation.
