Small-Scale Question Sunday for November 20, 2022

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

If your main goal is Rimworld performance, AMD's 5800x3D CPU is going to be the best value you can buy (or the 7800x3D when it comes out next year) because its huge cache makes a big difference (up to 40%) for complex sim games with lots of entities.

I've been drooling over these for Factorio, but similar sort of position where I can't justify it for the ~2hrs a week I spend using the PC that way.

CPU sim games are such an upgrade trap: "yesss, now I can simulate seven million pieces of iron moving down a belt! Progress!"

The widely-touted Factorio benchmarks run at well over 200+ UPS. The outsized gains from the big cache don't hold up as well with larger factories that struggle to maintain 60, presumably because they overflow it. Something that does help Factorio run faster on pretty much any computer is forcing it to use a larger page size with mimalloc.

Even in that case it's going toe to toe against a CPU twice its price with vastly higher single core speed, which is pretty amazing!

Thanks for the tip. If my business programs were available on Linux I'd switch over entirely at this point.

Interesting. Never thought about the cache mattering. Thanks for the tip.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
