Small-Scale Question Sunday for March 5, 2023

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.

Currently on a 1060 6GB.

Buy a 3080. If you don't have enough money, save; anything slower is an objectively terrible deal. The 4070 will likely be a 3080 equivalent (just like the 3070 was a 2080Ti equivalent), but it's also going to cost as much as the used 3080s currently do anyway so it's up to you if you want to wait.

The problem with the 3070 is that it's 80% of the price for 60% of the performance; this is also true for the 3060 as compared to the 3070 and the 3050 as compared to the 3060. (This is the root of why tech bloggers complain about every new GPU launch, because it's not the "3080, but for 400USD" that everyone actually wants but can't buy.)

ML workloads function just fine on it; sure, the 4090 is twice as fast, but going from 1 iteration a second to 10 iterations a second is a much larger leap than going from 10 to 20 and it still can't run Facebook's LLM anyway so there's no real loss there.

I can't guess if nVidia has another doubling of performance in the pipeline for the 5000-series, but if they do it's probably going to cost roughly 1.5x what the 4000 series did because if they don't they'll likely end up cannibalizing their Tesla sales. Either way, it's probably not going to completely tank the resale value of that 3080, which will probably be a perfectly serviceable card far into the next console refresh cycle (which is the other half of the reason for why they're so expensive- the 8800GTX of 2006 was twice as expensive as the 7 series, but also had twice the performance and wouldn't be meaningfully topped for a very long time and as such was absolutely worth the initial asking price).

Also OP can consider AMD gpus if he wont use cuda. Depending on his market, he might be able to get a 6xxx card for cheaper than nvda counterpart, especially used.

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!
