Chinese chipmaker shares surge 470%

17 hours ago (bbc.com)

Prediction - we are going to figure out SOTA AI performance without requiring 1TB of memory within a year or so.

Of course CXMT, Micron, and family will still be profitable, but maybe not 'surge 470% from IPO' profitable.

  • How would we do that? There's no historic precedent for that. Its fundamentally an information theory thing: what's the max amount of intelligence you can get out of 1 KB/MB/GB? There has to be a limit and I'm not convinced that it's far off.

    • Once I start a conversation about Postgres query plans, maybe 95% of the knowledge will be almost certainly not needed, and for an inference provider there will be many more concurrent queries with reasonably large overlap. Maybe future architectures will be able to take advantage of this so not all parameters are needed in memory for almost all instances.

      If we are talking about all knowledge, then I agree that the compression ratio is very impressive already.

    • It doesn't matter. However much intelligence you can squeeze into 1 GB, people will always want more.

      Standard Def TV was plenty for 50 years. But when more was on offer, everyone went for it, and now you can't even buy a 480p TV.

    • All the terms are squishy, but being sloppy about it, I think there's intelligence that needs to be in the model, and knowledge that could live in a database. Right now, models are memorizing a lot of stuff they don't need to. We know how to index lots of information on (comparatively slow) SSDs or across a network.

      See Karpathy's "Cognitive Core" idea. (I don't have a good link)

    • So far, frontier capability keeps getting shrunk to fit consumer level hardware. The lag time being over a year, though, precludes this from being called SOTA by the time it arrives.

      There must be a limit, I agree, but there have been no signs of approaching it yet. The most recent cohort of small models have shown the biggest leap in capability so far.

    • Historical precedent: Quickselect, or any other discovery of a surprising algorithmic speed-up.

      LLMs haven’t been on the scene for very long. There’s still lots of room for efficiency discoveries. Plus, I keep hearing quantum is going to be a big deal in the next few years.

      Sure, it might be very near using the current approach, but... it might also be might be very far off because we are using the wrong approach.

      I mean, look at the max amount of intelligence you can get out of a human brain powered by two bananas...

      Maybe? Human science history is absolutely littered with examples of things that were “constrained” by a fundamental law … until they weren’t, because we’d misunderstood or misapplied the law.

    • Just replicate dogs brain. It is the ultimate state of art (far smarter than people). But you need a few kb of memory to replicate resoning skills.

      Dogs are very smart!

  • And by the time the models that require 1TB memory will be better.

    It's like people saying mobile chips are going to be better than PC chips... until they realize PC can be made of mobile chips too if that comes true.

    • No, it's like saying a chip that consumes 500W is going to be better than a chip that consumes 200W.

      This used to be true for the first several decades of microprocessors, and stopped being true in the early 2000s.

  • The fundamental issue is that for these systems bigger is essentially always better (if affordable). So if we can squash something like Kimi K3 down to run on a 'normal' system, that just incentivizes devs to increase the model size until once again we're at the limit of what can be run.

  • What do you base this prediction on? It seems very unlikely, unless by SOTA you mean the current SOTA.

    • > What do you base this prediction on?

      Their posterior. Or worse, their interest in going to the moon (HODL style, not Artemis style).

  • I think the chipmakers are pretty securely set up here, the usual cyclical issues aside. Between the stubborn resistance of the data to being compressed without significant loss, and to a lesser extent the ability to do more with more memory (we’re surely at diminishing returns for LLMs already, but diminishing doesn’t mean zero) it seems like a fairly safe guess (I am not an expert on anything) that for the next decade at least you’ll still want at least 128-256GiB of video RAM to have a comfortably “SOTA-enough” experience. Then the other side of the rectangle comes from putting that VRAM in every consumer and office-worker device. Selling everything at a big premium to a few efficiency-obsessed SaaS providers is what you do when you’re temporarily supply-constrained. Sidelining the SaaS middlemen and selling to gloriously inefficient consumers who will leave their laptops closed for most of the day is the dream. This is probably not unrelated to the fact that the country which is currently making a big strategic push into memory manufacturing is also championing open models.

  • It sounds like you have strong faith that if we can do in 100GB what we can do in 1TB today, 10x-ing our model size[1] from today won't be better?

    [1]whether it is 10x in size, or maybe running 10x the models to have things like judges etc.

  • SoTA AI will move well past 1TB+ memory requirements in 1 year or so.

    Also, you will be able to play with much more competent models locally. They will still feel like children compared to the adults living in the SoTA region.

  • And besides llm's memory requirements:

    -HBM has a lot of room to grow(bandwidth/power/density). And an HBM memory takes 3x the amount of wafers of regular DRAM.

    -HBM + better DRAM designs could increase random memory access speed by alot. I've seen research talking about 7x.

    At what point it makes sense that half of consumer GPUs and most of the server GPU/CPUs start using HBM?

  • Are you thinking of fundamental architectural changes (like the Transformer)? Or incremental (like MoE or GQA)? Are there specific neolabs or techs you are following that lead you to this prediction?

    Indeed it seems quite possible we are one architecture breakthrough away from existing chip stock driving us all the way to ASI.

    Nobody has done AFAIK the information theory to prove it’s not possible.

  • Yeah, you can directly print the SOTA AI model on the chip. I also believe this can be done on older process nodes. The most important factor would be speed. How fast can you go from new model to new chip?

  • I'm looking forward to being able to buy CXMT chips for running SOTA models locally. :)

  • You can get _better_ that SOTA AI performance by burning the weights directly to silicon, the problem is you're locked into that model

  • that would be perfect timing

    Hyperscalers are screwed, data center mania couldn’t even be completed during this massive spending spree, all while the people seemingly sitting on the sidelines are working on getting these things baked into the OS and chipsets in a way consumers wouldn’t notice

You would think that the DRAM shortage would propel Europe to invest in DRAM fabs. But no, they think it's too risky because prices may fall in the next few years and building fabs costs a lot of money and is hard. They'd rather sell other people's stuff than make it themselves.

Ergo, the Chinese will take this sector too without so much of a whimper from Europe.

In a couple of years the Chinese will own 25% of the DRAM market and make bumper profits akin to Big Tech. Europe's response will be to levy import tariffs to at least siphon off some money from it.

  • EU will regulate itself out of everything, sit, cry and complaign about devastated economy.

    Noone votes for these ppl and stupid decisions they make destroy everyones lifes.

EU chip industry: best I can do is eat glue in the corner.

  • EU chip industry: best I can do is supply chips that are in 99% of industrial equipment and vehicles. Also supply the only machines in the world that enable leading edge lithography processes.

    • No comment on the second part, but the first part is wrong. EU doesn't have a moat in process technology anymore (since 2010s). They have a bunch of legacy fabs, like 350, 180 and 130 nm but Taiwan, US, and China (and others like Israel, or Singapore) have these too. EU is severely lacking behind chip design, production and packaging capabilities for industrial, automotive, and space kind of niche applications since the heavy divestment from semiconductors after 2008 financial crisis and 2015 Euro crisis.

      On top of this, once European giants like NXP (formerly Philips semiconductors), Infineon (formerly Siemens semiconductors), and ST are actively reducing their footprint in Europe and moving to India or SE Asia.

      In short: No, EU has no future in those markets as designer or producer of chips.

    • This is actually at the core of our (EU) problem. Instead of thinking, "here is this new technology, how can we build new markets/products out of it", our industry leaders always think, "here is this new technology, how can we apply it to our existing industries".

      You can see it a lot in AI, right now. AI4industry is not where the gains are right now. We should be competing on training foundational models. Once the foundational models from US/China are strong enough, they will do AI4industry and we wouldn't have any edge on them anyway because their tech is more vertically integrated and they have better insight in how AI works under the hood.

  • CXMT uses old Qimonda patents (even though Qimonda's tech is now outdated), and the former CEO of Qimonda is currently building a fab for an FeRAM-based alternative to DRAM in Magdeburg. It's a gamble as FeRAM still suffers from a more limited lifetime than conventional DRAM at this moment but I think there are still somewhat interesting developments happening in Europe.

  • To be fair, all high end chips are made in Asia with EU tooling. US happens to be the place where the managers are and the trade is facilitated. There has been some good progress to push Asia make cips in USA with EU machines however IIRC significant part of the chain is still in Asia and chips made in USA are shipped to Asia for further processing.

    Edit: changed China with Asia to distance the comment from Taiwan-China based politics.

    • > US happens to be the place where the managers

      And you know.. the actual design for plenty of these chips. By that definition Apple is also an Asian company..

      > with EU tooling

      That is only a (vital) part of the supply chain, there are plenty of other components.

    • AFAIK the high end chips are made in Taiwan, that's not the same. Also there was an export control, so ASML couldn't sell the latest equipment to China.

    • > To be fair, all high end chips are made in China with EU tooling.

      Did you mean Taiwan? Because depending on who you ask that is, or is not china.

      The Chinese have been cut off from EU tooling for a while now. And their attempts to build out their own lithography setups have been a failure. Their 7nm process is, by all measures, not delivering the yields that one would need to make it really successful.

  • Don't make me tap the sign that says "ASML".

    Difference between Europe and the others is that it doesn't brag nearly as much.

    • And that’s about it..

      In relative terms there is no innovation happening outside of that and some other smaller companies providing highly specialized components that are a part of the supply chain.

      There isn’t just much if anything to brag about. ASML is great but it’s effectively a monopoly (for the time being) due to a large extent some correct historical choices.

  • You're forgetting about ASML, which is European and makes the actual machines to produce a huge portion of the world's high-end chips.

  • > EU chip industry: best I can do is eat glue in the corner.

    Aren't they the only ones able to supply the chip-making machines?

    • Based on the empirical evidence we have ASML succeeded in spite of the EU not because of it (so “they” is bot exactly fair). There is not much EU has going on besides that when it comes to growth and innovation.

      It’s a bit like Novo Nordisk, they had a huge win and then just focused on making as much money while it lasted while more innovative companies ate up their market.

I have nothing to say about this company's long term potential, but I'm curious to know whether this will become an enormous "tik stok" like SK Hynix became in South Korea. I've watched a short documentary about the investment mania in SK and it's really scary.

  • The DRAM market is a notorious pork cyclic business. SK Hynix and Micron have stood on the brink several times.

    No matter what happens the Chinese will carve out a niche since they're playing the long game. And DRAM will always be needed.

  • South Korea has opened its financial doors to the outside world, and since SK Hynix is a publicly traded company, that's allowed capital to flow in and take control of the company.

  • > the investment mania in SK and it's really scary.

    i mean, it shouldn't be scary, because their failure is their own, and i doubt there would be collateral damage outside of those high risk investors.

    It's scary for _them_, but it's an interesting case study for an outsider.

    • There's a lot of speculation in your comment.

      I lived through the crash of 1989, the Dot Com crash in 2000, the GFC of 2008, and whatever the crash and WSB speculation in 2020 were called. None of them had a tiny blast radius like you suggest.

    • If 30% of adults in your country suddenly lose, say, half their wealth from a stock market crash, it's going to affect everyone in the country - not just the investors.

      To use an example, the Great Depression wasn't sunshine and roses even for the people who kept all their money under the mattress. Their job was just as likely to go out of business.

If the golden stick of memory sitting on Trumps desk has its intended effect - and the US allow Apple to buy memory from CXMT then another 500% surge might happen.

  • The reverse might be worse for the US in the long run.

    Right now, the US leads China in compute-heavy R&D because the US has access to more compute, and that compute has two components that China has limited ability to produce domestically: the GPUs themselves and the DRAM. A decent fraction of the balance of the plant is already produced in China.

    If the US refuses to buy Chinese tech, then we may find ourselves paying more for compute than Chinese labs (DRAM first, but Huawei really really wants to catch up with the combined forces of TSMC, Nvidia and AMD) and falling behind on access to compute at acceptable prices.

    If I were setting US policy, I would be trying to get the US-friendly companies to increase production and trying to encourage domestic production so that the US-friendly world can stay ahead. Getting held back by a DRAM cartel that wants to juice profits at the expense of output is not good for the US.

    • > If I were setting US policy, I would be trying to get the US-friendly companies to increase production and trying to encourage domestic production so that the US-friendly world can stay ahead.

      That's what the CHIPS Act was supposed to do, but it got neutered for partisan political reasons. The CHIP Act was already about a decade too late. US policy is inconsistent across administrations, and the beneficial moves usually made very late in the game, around the time second- and third-order effects of the bad decisions become unbearable.

> Once an affordable component used to build devices, memory prices have more than doubled in recent months - and are still rising.

Is this accurate? It looks like they are no longer rising, at least for DDR5 memory:

https://de.pcpartpicker.com/trends/price/memory/

Most of the price increase did occur in Q4 2025 and most prices are fairly stable since then. Maybe this is different for LPDDR, GDDR, or HBM, but I would like to see evidence for that.

The more interesting question is: why does the rest of the world not increase their production prowess? I am aware of most of the reasons, but I am getting tired of the "China is better than the rest of the world". It is more that China did a lot of things that the others either failed to do or no longer wanted to do. Case in point is Germany: from "our cars are best" to "hey, chinese cars are now better" (or, cheaper, for a comparative quality). This constant complaining is so strange. Would that energy not be better spent to try to become better?

  • 50 years ago you could ask the same question about Europe, the USA and Japan: why are they so much more productive than everyone else?

    So others did spend energy on becoming better and now you see a different picture when you look at the world.

  • The short answer is VW doesn't have the ability to compete with China's best EV car company on EV price, factory automation, or raw input (labor, electricity, metals) economies of scale. The complaining is to get politicians / regulators to prevent the Chinese EVs from being imported into their domestic markets.

    Chinese structural advantages: monetary policy, lower cost of living, better infrastructure (electrical and transportation are all new within the last 20 years), lower cost of {concrete, factory machinery, metals, electrical} due to economies of scale.

    Chinese EV manufacturers advantages: they don't sell ICE cars, so they don't have any legacy customers, factories to retool, or brand migration issues. And they mostly stole their technology from hiring Tesla factory workers to moonlight for them and share the design, technology, tooling, and RE the Tesla finished product.

    Major Western legacy car company disadvantages: Ford, Toyota, Volkswagen, etc... all have significant reasons why they can't or won't make the super risky attempt to go all-EV. They all have $10s of billions in debt they are still paying off for their current capital improvements. Those debts assume they contribute selling ICE because EVs last longer so they would sell fewer units per year. It's simply less risk to avoid making any EVs and pay politicians to protect their businesses than to try to compete with 10 year old Chinese phone-companies-turned-EV companies. On top of that, the worldwide demand for EVs is only about the volume of the single most popular model of Toyota. They would have to go into massive debt on a giant risk that consumers will want more EVs (and that the EVs they design/build will sell better than the current ICE cars they have meticulously crafted for 50-100 years).

    • > And they mostly stole their technology from hiring Tesla factory workers to moonlight for them and share the design, technology, tooling, and RE the Tesla finished product.

      Did they successfully steal Tesla's low-cost EV plans too? Using the traditional definition of "steal" (depriving the owner of their property.) The argument that all China is good for is stealing falls apart[1] the second Chinese products become superior (see battery chemistry).

      Perhaps Tesla should pay Chinese EV designers and PMs to moonlight for them to shorten their model development cycles.

      Domestic Chinese EV competition is fierce, if one can survive or thrive in that boiler, dealing with VW, Ford, or even Tesla is a cake-walk.

      1. Nevermind the growing body of fundamental research papers published. An area the US is turning it's back on because some people are gassing themselves up on they idea they are intrinsically, and immutably great/superior, therefore there is no cost to wrecking stuff to "own the libs"

  • Because the capitalist west doesn't have strategic view, beside maybe on the defense sector. Everything else must produce profits next quarter not in the next 3 years.

    • It's this. Wall Street won't allow american companies to make long term decisions and long term planning that cost money in the short term, because they want all that money immediately now. Like, right now now. If an executive promised they could deliver big profits in 5 years by spending the next two investing their profits, Wall Street would fire them and put in someone who will happily spend all the profit (plus debt) to do stock buybacks and dividend disbursals.

    • It's even worse, the entire ideology is that industrial policy can't, by definition, be better than what the market would decide without interference. So every kind of actual strategic decision making (i.e. investing a few hundred billions in the industries of importance for the next decade(s), or at least in the infrastructure supporting it) would actually make matters worse. That is essentially what neoliberalism is all about.

      This is core reason why the German industry became so irrelevant in the last 2 decades: The rail infrastructure became pseudo privatized and now is in shambles (IIRC only about 60% of trains arrive on time). The PV industry was axed by the conservatives about 15 years ago and now is completely dominated by China. Even now, as the other EU countries demand strategic investments - and again the German conservatives say this ought to happen without any new debt. "We can only spend what we have", to quote Merz. Imagine China saying this about chip production, or even Sam Altman about compute hardware...

  • It is because in the west we suffer from self inflicted obstacles that make it impossible to get out of our own way. The Chinese gov must think they are playing on easy mode.

  • > Would that energy not be better spent to try to become better?

    The problem is, shareholders have bled Western companies dry in the chase for returns on investments. There is no money left in the companies to retool them to be competitive with China.

    Meanwhile, the CCP just pours dollars into their companies.

    Unfortunately, there is no punishment in Western societies if you run a company into the ground as long as you pay your debts on the way out.

    • Private equity has mastered the art of running a company into the ground, hiding that fact, and handing the debt over to someone else. So there is no punishment even if your don't pay your debts.

  • The rest of the world is chasing models of investment in procurement of goods and services that get stuck on neoliberal capitalist antipatterns where every action demands a short-term profit motive. These are now very large-scale, highly-complex-supplychain manufacturing projects, and you cannot remain competitive if you are just Putting Faith In The Market to solve your problems. There's too much planning and sustained, structured goal-orientation required for investors or for the sort of contract-bid, public-private actions Western politicals are used to engaging with.

  • It takes 2 years in EU to get approval to build a shed. Imagine how long it takes to get approvals for a chip factory which uses a lot of water and very toxic chemicals.

    UK has been trying to get approvals for a new runway at Heathrow airport for over 20 years !!! now.

    • The EU isn't monolithic, you could probably do this fairly easily in someplace like Poland where there isn't a bureaucratic hell and a large supply of skilled workers and engineers. But of course, Poland and co. are the "lessers" in Europe where you outsource for cheaper labor, a prestigious thing like a cutting-edge chip fab would need to be built somewhere like Germany or the Netherlands, and so it never shall exist.

  • Mostly self-inflicted wounds in form of climate pledges, climate taxes and such. Because of the goal to achieve zero emissions goal and climate neutrality, we abandoned cheap energy sources such as coal and pushed our heavy industries out of Europe to China. We still need those products, so we import them from China while wondering why European industrial segment isn't growing. Even in the clean energy sector, most solar panels come from China.

    • on the other hand, if those climate goals were stuck with, we could be just fine with $500 barrels of oil, and could just not-care about the middle east

      solar and wind will always end up cheaper than coal because the fuel is free.

      we certainly should be making our own solar panels and such, but we can get so much cheap electricity by building tons of renewables that that heavy industry can run in much-less-pollution fashions anyways

      of course, having a liveable climate is up towards the most important things for having a good economy. france being 50C all summer isnt conducive to doing much of anything

Let’s see them ship some chip first
