Cpu Stress test with factorio

[Pat]

I would like to make sure that my cpu can handle even the biggest of biggest factories
so i can keep expanding
Anyone has a link to the biggest and most resource intensive factory?

https://factoriobox.1au.us/results I recommend this site. Has enough maps and a lot of benchmarks.

thanks will try

Just bear in mind alot of those are heavily optimized

Well yeah it's more for comparing different cpus rather than how much you can do with your cpu.

I've found that the biggest issue in the game is size of the map. You can really screw over your game and kill performance by getting too many artillery range upgrades. I suspect rail pathfinding over long distances is also a performance hog, or at least the need to have more trains to compensate for long distance train travel makes for a big hit. Fluids aren't really as much of a problem as people used to make them out to be. Just try and build a compact factory and fill in lakes so that you aren't expanding out too far. The bigger the map, the more nests, and the biter pathfinding takes a real toll. Think in terms of surface area and how many chunks need to be activated beyond those strictly for your factory production buildings and belts.

What it comes down to is not CPU speed but rather memory bandwidth. You want as much cache on your CPU as possible. Bigger L1, L2, L3 lead to better megabase performance. The more stuff in your base, the more memory required, and the more of your base exceeds your available cache size the more the CPU has to pull stuff from your RAM. It is this RAM access that slows you down the most.

So, while the necessity of producing more and more stuff is unavoidable if you want higher SPM, you can try to minimize the performance impact from having excess active chunks or more biter groups pathfinding along your borders in order to keep RAM access to a minimum.

Can confirm. All the factorio benchmarks I have seen are dominated by the amd ryzen cpus with 3d caches. And the faster the ram the more ups they get.
