OK I’ll take the bait. Were devs supposed to optimize RAM for a shortage that might come? I’m guessing you had enough foresight to stockpile RAM?
Time to bring back 32 bit OS, that way you only need 4GB RAM per computer!

HBM requires stacking the chips. So they need to shave the layers, glue, stack more, shave again. They also require a substrate what is even more wafers. The issue is that a error in the stack means a lot of losses. In order to get high bandwidth, you want memory as close as possible to the GPU. The more trace lane length = signal loss, bandwidth loss.. HBM is compact, and so you can stack 24GB modules, 8 around a GP…
None of what you said actually explains how HBM could require 3x the wafers. The base interface die has eight or 12 memory dies stacked on top of it. The wafer cost of that interface die is therefore small. If the process of die thinning and TSV stacking reduced yields by a factor of three, nobody would consider HBM mature enough to put into production, and especially not mature enough to be increasing stack height f…

Why must you increase the price?
It is the other way around, When people want something they are willing to pay more for it. The manufacturer wants to sell to the person that will pay the most. While the person wants to buy from the manufacturer that charges the least. As such when the manufacturing capacity is below demand the price goes up until the item is worth what people will pay for it(at large, statistically, it works like an auction). The p…
If you happily sell apples for $1 and see a hungry person walking towards you, must you raise the price?
I think that basic thought gets lost sometimes when people talk about shortages causing the price to increase. The shortage didn’t cause anything, some executive decided they want more money. That’s all. There’s nothing inherent in the system that requires it. Whether that’s OK or not is up to the reader, I just think people lose sight of the reality and talk about it like it’s gravity, rather than simple decision making.

The problem isn't the price. No matter how much you pay, you can't take delivery of a chip that doesn't exist. Now, you could raise prices to the point where you destroy demand. But that's a tricky window to maneuver through.
> The problem isn't the price. No matter how much you pay, you can't take delivery of a chip that doesn't exist I’m confused because this reads like a denial of basic economics. If the price is high enough, the chip will be produced for you. Do you mean because of the production lead time, higher prices won’t result in increased production? Commodities like corn have been managing this for a long time… what’s special…
Samsung, SK Hynix, and Micron have a combined market share of 90% - with most of the rest being a very new-to-the-market CXMT. It is a cutthroat market which behaves like a stereotypical "pork cycle". Semiconductor fabs cost billions to build and take years to complete, so you better be damn sure you have buyers before you start constructing one. You and your competition overestimated the demand? You have to pay back the construction cost, so you're now in a race to the bottom and one of you is going bankrupt.
Ever wondered where Intel came from? They started out as a DRAM manufacturer, which dominated their revenue well after the introduction of their first microprocessors. But in the early 1980s the glut of supply from new Japanese manufacturers made it so unprofitable that they had to ditch the memory market altogether. The stories of Texas Instruments and Motorola aren't much different. And that's not even mentioning the likes of Mostek, which once held a 85% market share and was dead less than 5 years later! Oh, and those Japanese manufacturers? All gone, pivoted like Intel or died like Mostek.
So no, the three remaining DRAM manufacturers aren't going behave like headless chickens and start ordering new fabs just because there's a bubble causing a temporary demand peak. Unless those AI companies are going to pay in advance, in cash, for an entire fab, they'll just have to wait and deal with the price increase.

Well, the Chinese manufacturers are certainly coming, though CXMT seems to be being careful not to rock the boat, at least yet https://www.tomshardware.com/pc-components/dram/chinese-cxmt... .
It makes sense, CXMT takes as much profit as possible, then use that money to build more capacity, ultimately becoming one of the biggest competitor (only?) to the cartel.

Is that really competitive with just doing a pciexpress card with faster M2 SSD ?
Optane on a cheap adapter is superior in just this Swap application because the 16GB M.2 are very cheap, the 2x lanes aren't under utilizing your 4x motherboard M.2 slot when used with an adapter, and Optane has better write endurance and latency then even the newest flash.

Why must you increase the price?
The alternative is to have shortages. If there is demand for N chips at $X price, but you only have N/2 chips, then half the people aren't going to be able to buy them. The people who really need the chips, and would be willing to pay a lot more than $X for them, will be competing with people who are only willing to pay $X for them. You will end up getting scalping and shortages and hoarding. Since people know that t…
I don’t believe scalpers are an issue in B2B; these aren’t concert tickets being sold to the general public.
It’s clear you grasp the economic theory as it’s taught, but my comment was meant for you to question it. If someone is hungry you can charge more for food. The market allows and encourages it. But don’t mistake that for “willingness” and don’t mistake raising the prices purely to get extra money from the exchange as some inevitable law of the universe. You’re welcome to love the concept, but don’t whitewash it.

Corn is heavily subsidized,also has (in the US) federally prvided insurance programs against plunging prices, has paid uselessness(ethanol). Despite all of this corn has caused massive agriculture bankruptcy/takeover when it has failed anyway. So it's more "what's special about corn". It is also fairly hilarious to claim the parent is denying basic economics and then bring up corn as an example of having successfully…
I don't think that anything you said is wrong but I also don't think that memory consumption is going back to the old baseline... well, ever. Memory is just too useful now that you can use it to drive cars and write code.
Which directly leads to the next big development: all the big players are investing in silicon with "baked-in" models, like [0,1]. Turns out you don't need an expensive general-purpose GPU with heaps of RAM to contain a model when you can make a custom ASIC around one specific model! Why spend a fortune on DRAM / HBM when all you need is some finetuning parameters which are easily stored in on-die SRAM?

Almost everything we consume is downstream of RAM pricing. I don’t buy a phone every year, but corporate workforces, streaming servers, cars, factories, etc. will all cost more next year.
Oh, I hope you are right about cars. If one of the outcomes of the memory crunch is that manufacturers start making “dumb cars” again, it would almost make it all worthwhile.
In the shorter term, you’ll probably see more “base” models on offer with some of the most intensive features disabled. There’s still going to be all of the telemetry stuff that makes them money through third parties though.

What’s wrong with a signature?
Signatures are completely pointless. Literally draw squiggles as anyone else can. Nobody ever checks or compares them to the original, how can they?
