Interesting to me because this is very likely to drive Linux support and usage in Mainland China!
Windows is unlikely to ever support LoongArch.
Had a very enlightening discussion with the authors as well, kudos to them for an amazing article!
What’s the game theory-ish take on this? Isn’t cutting off China’s access to chips counter productive in the long run, because of course they’re going to throw the country behind being self sufficient in this regard.
Is the process where cutting off an opponent’s access to a resource causing them to become more powerful a thing?

I am fairly convinced now that in about ten years time, the tech war will be seen as a huge strategic blunder.
It is said that post WW2, one big stabilizing factor of the world is that we globalized and created interdependence on the 6 continent supply chain. It was in part due to technology gains, cheap energy and resources to power that tech and the fear of creating enemies that could now potentially fight back with nukes. A truly existential threat. If we all lean on each other to some degree, it works out better for most folks.
And now we see that this is rapidly degrading over the last decade.
I think the belief was that if the west cutoff China, they would be left in the dark. Instead they have more than enough knowledge on how to make these things that it became a driving force to active decouple from the west.
Provided the other economic/demographic/political issues don't become a major problem to China, this will definitely be a large blunder.

The San Francisco System is proving as strong as ever especially with recent deals inked between NATO members and US allies in APAC, wtf are you talking about?

without tech war, China could progress much faster in emerging tech(AI?). But since there is no counterfactual data, there always will be people who use this to push narrative.

The blunder would be guaranteed if China spends a small fraction of the time and effort thinking out of box to look into other computing paradigms ... and relaxing some of the unnecessary limitation on individual rights, private properties, etc.
In ten years time, China will be older and broker and with even less international friends. It would be a great strategic triumph.
Don't get your hopes up. Europe, Japan and S Korea are aging quicker and more countries are sympathetic to China than the US.
The time to clip China's wings was the late 90s, but we were too drunk on triumphalism and busy looting Russia.

At this point, arguing about democracy feels like the political equivalent of saying "I went to Paris, and spent the whole time moaning that I couldn't get Del Taco." I guess it doesn't matter if a country is raising its quality of life metrics, or advancing up the economic ladder. Whether the population is content or satisfied with its leadership? Nope. The only relevant metric for human achievement is the invention of a multi-party electoral system.
Except it's even worse than that. It's so easily reduced to parody because it was a strawman to begin with. We don't really give a flying ** about democracy; if that were true, would we have backed the string of strongmen running South Korea in the first 35 years of its independence? Would we ever let a single dime reach Saudi Arabia? I wish our leaders would be honest about it though-- if we just said "we have economic and military hegemony and it's our mission to preserve it", then nobody will waste their efforts trying to find middle ground and win-win solutions.
We should ask why China is winning hearts and minds overseas: maybe they're prioritizing the things people actually need? They don't come in and airdrop a half-baked democracy on a country with little interest in it. They've been loose with the economic aid, and have strayed away from the Western/IMF "let's demand massive austerity and privatization" gameplan. There's nothing stopping the US from doing the same things, but with a bigger bankroll to play with.

1989 Tiananmen Square protests and massacre
Nice rhetorical device.
Now, could we try some strategic empathy, learn about other people around the world, why they despise us, and maybe try to arrest the collapse of the West?
Or are we ok with just snarky mismanaged decline?

By its proponents? It's already apparent to many. The current trade war started already over half a decade ago under Trump.
Yes. I think in the US politics "blob" eg. the sanctions against Huawei are still seen as enormously succesful in the sense that they did huge economic damage on the company without China being able to retribute directly. However today Huawei mass-produces a modern high-end phone and if you open that phone, none of the components inside are produced by western companies, everything is Chinese. That is really remarkable. And it is not going to stop with a phone.
Perfect case of winning the battle and losing the war .
nope, the tech trade war has always been there since the country was founded in 1949, for tech such as semi conductors, machine tools, industrial software, etc. US just escalated it by placing more restrictions and targeted large swathe of the CN economy. But because of the decade of sanctions, the R&D industrial base for many of these tech is there, just very small, no market maturity, but there is human resources, there is IP and know how. Sanctions just give these actors a chance to really improve.
Powers that be are betting that the Chinese won't be able to catch up.
These folks might be swallowing the "Chinese aren't creative" too long
An alternative explanation might involve both of:
1. Stopping technology transfer worked exceedingly well for the west weakening the Soviet Union during the Cold War.
2. A distinct lack of (non-violent) alternatives for the West preventing China becoming the world's leading technological superpower (and hence also strongest military).
I doubt this will be successful in the long run, because China is not burdened by the Soviet Union's extremely inefficient way of organising its economy. Not to mention that China is the worlds biggest market.

I think the same, this is disadvantageous long run, but I'm not in power and the people in power appear to be complete morons with little understanding of history or nuance.
I'm pretty sure we're rapidly heading into a West vs China military conflict. I think part of the reason we've held rates higher for longer is that it hurts China more than the West as a way to undermine the Chinese economy. Coupled with the sanctions the West is getting ready for a 'timing attack'. But if the West is wrong and loses that war then we're effed. I would prefer a graceful stepping down from world hegemon and taking our seat at a multipolar world where we can focus on getting our own house in order. But obviously those in charge have other incentives.

Don't say that sort of thing too loudly; JFK quoted a chengyu (骑虎难下) in support of a similar notion, in 1961 (and for his pains got cancelled in 1963): https://www.jfklibrary.org/archives/other-resources/john-f-k...
It will work in the long run due to China’s terrible demographics, which are worse than Japan’s; and Xi’s extreme mishandling of China’s economy and foreign relations which are both intertwined.
All that’s needed is a military containment of China.

> China’s terrible demographics
Are China's demographics appreciatively different from other industrialised countries? Questionable. Not to mention that it's unclear why an aging society is a problem at least for the next 100 years or so (e.g. most violent crime is perpetrated by the under-30s). It's also easy, at least for a dictatorship, to increase the birth rate (e.g. restrict access to all birth control, give massive preferences to families with children, like housing, salary, "bachelor tax" etc).
> military containment of China.
That is expensive. One frequently cited explanation for the collapse of the Soviet Union was that its poor economy could not support its oversized army, which it needed to keep the Soviet Bloc at heel (not to mention all the revolutions and secession movements it fostered elsewhere).
Also, does anyone actually believe that China is expansionist? Compare:
https://en.wikipedia.org/wiki/List_of_wars_involving_the_Uni...
https://en.wikipedia.org/wiki/List_of_wars_involving_the_Peo...
The strategic problem of China's rise is more that other countries will eventually switch allegiance away from the West.

"Are China's demographics appreciatively different from other industrialised countries?"
Yes. Also, it is very likely that China has been covering up the true extent of the demographic problems. And not necessarily to hide it from its geopolitical rivals, but to hide it from its own leadership fearing purges and punishment. Like ... there's a 100 million people "missing".
"it's also easy, at least for a dictatorship, to increase the birth rate"
No it's not, because those changes take a while to implement, and even if the birth rate skyrockets, you don't get usable workers for 20 years.
Plus, China's economy is urbanized, and its economy is built around cheap labor that is worked to the bone (996). To make urban areas viable for raising kids, you need to decrease hours worked and increase wages.
And, people need to feel optimistic about the world and the future.
So lets say a massive sweeping change was implemented to make having children quite a bit more appealing. It would probably take about 5-10 years for the policy changes to trickle through the various layers of state control (China is kind of feudal in nature), monetary incentives will likely be greatly reduced by corruption.
Then 20 years later, you start to get a blip upward. Because the issue is, the people that will have the kids are ALREADY THE SMALLEST GENERATION EVER from one child policy. So to move the needle, they need to have ... like ... 8 kids each.
One child policy forced families to pick a gender as well. You won't believe this, but culturally people preferred boys. So the smallest generation ever, which would be 50-50ish, is more like 40-60 or 45-55 (maybe not that stark, but ... kinda is) then ... well, your expansion is limited by the wombs.

So, keep in mind Zeihan is a bit of a clickbait artist. He sells himself and makes bold claims. But if he is right about those new vs old/fake numbers, that is some bad stuff.
The solution to falling birth rates is immigration. And while China does see a lot of immigration, it does have a large rural/urban divide, so it might be able to "immigrate" people from the rural classes (who as I understand it are currently treated as a lower class of people).

Nice propaganda. Meanwhile China is building islands in the South China sea and provoking violent encounters with fishermen and coast guards, causing nearly everybody in SEA to build stronger military ties with the USA.
The only ones to switch allegiance to China will be the ones who have been bought off.

Meanwhile, Vietnam upgrades ties with China, Singapore performed joint military training with China, the Malaysian minister blasts the west for having a too one-sided and hysterical view of China, and both Indonesia and Philippines report that Vietnam is actually the worst offender in the South China Sea issues (indeed, Vietnam already built islands 30 years before China). And when AUKUS was founded, were Malaysia and Indonesia happy that the west came to their aid to fight the evil CCP? No, they were alarmed. Just whose side is being propagandized?
Despite all of the ceremony, Vietnam still hates China with good reason too. China keeps invading it including taking the islands in the South China Sea that Vietnam laid claim to. I believe the PLA actually attacked and killed Vietnamese troops stationed on those islands.
I’m also confident that the Philippines will now claim that China is the worst offender in the South China Sea.
As for any country involved in the 9 point line including Malaysia, anyone would have to be delusional to think that they support China stealing their territory

The point isn't that there are no animosities between SCS countries. It's that representing the situation as "evil China invades other countries" is one-sided, misleading, and ultimately harmful for peace. Having border disputes doesn't mean that countries must have bad relations, nor that they cannot be solved through peaceful means. Insisting on the notion that the existance of border conflicts must point to irredeemably evil intentions stands in the way of peacemaking because it's a self-fulfilling prophecy. Of course, the powers that be want such a self-fulfilling prophecy, even if it's at the expense of south-east Asia, which is why they keep perpetuating this view.
China IS asserting control of territory claimed by other countries. Do you deny this? Whether or not China can justify their actions, other countries will be provoked.
Just face it, Xi is steering China towards another big leap backwards. All the foreign provocation is distracting from serious domestic issues.

Again, that is completely missing the point. The Malaysian minister just blasted this attitude last week. Every country around there is asserting control over every other's country's claims, and they all have overlapping claims. This isn't "China vs the rest", it's "everybody quarrels with everybody else" and thus it cannot be peacefully solved by one-sidedly focusing on just one party.
Malaysia and Indonesia responded to AUKUS with alarm, do you deny this?

I can't take your replies seriously.
Breaking and continually flouting international law and the de facto naval boundaries accepted by literally every other country in the world is not a small thing. Until that unreasonable position changes, it is completely irredeemable. For the record, China is making the rest of South East Asia suffer here, and not the US. This is one of many reasons why Vietnamese and US relations are stronger than ever. China is the aggressor here. it’s delusional to say otherwise.
> This is one of many reasons why Vietnamese and US relations are stronger than ever.
Let's say that even this reading is heavily disputed. I don't think the Director of the Global South Program at the Quincy Institute, and member of the adjunct faculty at George Washington University, is as "delusional" as you think. https://responsiblestatecraft.org/biden-vietnam/

The 4 no’s doesn’t counter my point. Just because Vietnam won’t openly side with one nation doesn’t mean that Vietnam doesn’t hate China. It also doesn’t mean that they will not take steps to counter China. It will just be a more subtle response.
Countries like the US have not seen as large of a drop in birth rates like China. Many countries in the West have also successfully used immigration to blunt the impact of falling birth rates.
Countries like China are unable to take advantage of immigration. If increasing birth rates were easy for authoritarian countries like China, they wouldn’t be in this mess in the 1st place. This is a terrible argument. This situation is made worse with many mainlanders are trying to leave China.
The US and its allies like Japan and Australia have already implemented containment of China in the island chains. Pretty sure that thr Philippines and Vietnam are on board as well. This wouldn’t have happened if Wolf Warrior diplomacy weren’t a thing. All anyone has to do is cut off imports from the Middle East to cripple China. (No, Russian imports aren't enough. Most of their pipelines were destined for the EU. )Even India can cut off Middle East energy exports on its own because China doesn’t have a long range navy.
The BRICS coalition has also largely been a failure because no one can agree on what currency to use.
If either the Hu or Jiang faction were still in power, none of this would have happened because unlike Xi neither faction was delusional.

Then why not cut imports now. Time will only make them more resistant.
In case you haven’t noticed, we’re not formally at war yet. The US historically doesn’t make the first move since we’re a democratic republic and most constituents do not like war; it would also alienate most of our nominal allies. The best the US can do right now is containment and being ready to cut the supply lines from the Middle East.
Washington can't even military contain the Houthis, or Iranians, or Russians.
1. Russia should have overwhelmed Ukraine years ago. Yet It’s still stuck. The EU is also finally mobilizing militarily. Also, this really isn’t our problem anymore. The EU can’t even give us good trade deals. They’re too busy passing one protectionist law after another. What’s the point when until now they were unwilling to pay their fair share into defense?
2. Iran isn’t doing anything but proxy wars here and there. Mostly in places where we will eventually retreat from.
3. Washington doesn’t need to contain any of them. Globalism is no longer a US interest. We are tired of subsidizing world trade and world security for little to no gain. All we get plenty of is criticism. Only countries that need energy imports from the Middle East are worried about the Houthis. Unlike many other countries, the US does not need energy imports or food imports. This is everyone else’s problem now.

1. This is factually incorrect and ahistorical. Russia obviously had no intention of "overwhelming" a massive country with half a million NATO-trained soldiers in 2022 with only 200K Russian soldiers. Even if the AFU wasn't a massive military, 200K soldiers is not enough to occupy that entire country.
2. I guess this is a way to dodge the Houthis question, who are actively striking US-aligned ships. What happened to "Operation Prosperity Guardian"?
3. And yet Washington does want to contain China? This sounds like "I can't lose because I'm not even trying".

This is merely a demonstration of China's general competence level in CPU design and fabrication. Loongson is poorly resourced and has only niche applications and sales. Huawei and Alibaba are at a completely different level of resource availability in comparison.
It is a thing but it depends on the opponent's will, orgsnizational prowess, resources and human capital. The latter includes talent pool and scientific knowledge. Not all countries can pull it off. Most countries don't have the scale necessary, many don't have the organizational prowess.
Resources spent re-inventing wheels is resources not spent gaining a lead.
Are you calling for the government to pick a winner? The Chinese word for this fierce if at times chaotic competition is "juan". It worked for them in EV and PV. The outcome remains to be seen in chips and commercial space launches. But even their mostly (ex-)students-run open source Xiangshan RiscV project https://github.com/OpenXiangShan/XiangShan shows a remarkable level of sophistication.
It might be about buying time - if our side develops some dominating technology before they manage to reach parity in chips, then they won't have time to catch up.
It's the opposite of "embrace, extend, extinguish".
The other question is, is it morally right? For what legitimate reason do we have to cut them off of chips?
The literal only reason I see is jealousy. Power tripping.
The whole weapons thing is bullshit. You don't need the top of the line ic to power military equipment. This is really just petty jealousy and economic hording by the USA.

In a street interview in China (Xinjiang, even) about sanctions, an old man gave an interesting answer. He did not express resentment for the sanctions. Instead, he said: let them sanction, in the end we can't rely on others for our own prosperity and development.
He is right. There is no point in Chinese resenting the sanctions. There is no point in foreigners criticizing the sanctions, we all know it's no use. The only thing that matters now is for Chinese to focus on work. Focus on our own R&D. No need to say much, just get things done.

Not only is it no use, but it's very counterproductive. It's hard to push for innovation locally as it's initially higher cost and lower quality so local companies are incentivized to continue to buy foreign. Without the customers to drive demand the top down initiatives invites corruption and money spent on it just goes into a bottomless black hole. By being sanctioned you have the foreign countries ensuring local companies can only by locally and are not able to bribe the foreign countries to circumvent.
From the US perspective it's different. I'm living in the US, I think we're being petty, disrespectful and I think the action is pathetic.
This is not about China resenting the sanctions. You already have the right attitude This is about a US citizen looking at the US and feeling ashamed at our own virtues.
We should share technology and work together. Not fear one nation surpassing the other.

Was that interviewed man in Xinjiang a Han or a Uyghur? I'd be challenged to think of something more duplicitous than a street interview in Xinjiang.
There are many more ethnicities in Xinjiang than just Han and Uyghur you know. Chinese typically don't focus on people's ethnicities and prefer to refer to people by their place of origin (e.g., "Xinjiang people", "Shandong people", etc), the Chinese way of being inclusive. The man appeared racially ambiguous, could just as well be mixed.
I have a Uyghur acquaintance in Germany who's pretty mad at the media's depiction of stuff. He views it as slander of his home region. At the same time he resents that most westerners don't actually care about the truth, they just want their viewpoints confirmed and get mad at him for presenting a different narrative.
He even gets death threats from other Uyghur diaspora for holding this view.

Colloquially, when Chinese people refer to Xinjiangren, they mean non-Han Muslim people. I heard a lot of casual racism directed towards them while I lived in China. Chinese are being "inclusive" because A. they are ignorant, B. they assume most people are Han, with the occasional minority that looks mostly Han anyway, and C. they associate a region with ethnicity or local culture.
All street interviews that are shown in media parrot official state talking points. If you don't understand that, I don't know what to tell you.
I think it's actually a shame that you now live in a society with free access to information but choose to take state media at face value.

I wish I could find it again, but I remember reading about how Russians are using an old style chip-screen. I don't remember the name and can't find it. It's kinda like a FPGA but it's not reprogrammable and can be done cheaply on small batches. Really neat tech.
I think the idea is to starve the Chinese on AI advances, but there isn't much point spending a fortune training such models when you can have an insider leak it to you for much less money.

But why is this a good idea? You're saying it as if it's obviously a good idea. Why not cut off the entire food supply from some impoverished nation in Africa? Is that justified? What justifies stopping AI advances or blocking technological progress in China?
Seems like the main justification is that we can't accept China surpassing us. That's not a moral excuse, it's a petty one.

It's not my idea, it's an attempt to explain the intent of the sanctions, I'm very against the sanctions for a multitude of reasons. If you see my other comments on this page you can see where I've stated that I would much rather, as you suggest, the West gracefully step down from a hegemon and take our seat at the multi-polar world where we can focus on cleaning our own house.
ah. We're in agreement. nm, I misunderstood what you said.
The US should act in its best interests, not China's. What's the advantage in helping a geopolitical adversary who has not demonstrated much capacity for "playing by the rules"?
It's counterproductive which means it is not in the best interest of the US and actually in the best interest of China. It only makes sense to me as prelude to a war and as part of a 'timing attack', if there is no subsequent war to then all that has happened is the creation of an indigenous industry for much less cost to China than what it would have been if China had tried to do it by itself without sanctions. To be clear, I very much don't want this war, for one I think the West would lose, and even if we 'won' the middle class would be crushed without access to cheap chinese goods.
The West would lose? How? China cannot project force aside from ICBMs.
So, it's to our advantage to give away IP instead of making them discover and invent things on their own? This is some r/latestagecapitalism level of nonsense.

Allowing the chinese to buy foreign goods is not giving away our IP it's selling goods which is what you normally do with goods. And yes it selling them goods would slow down their tech advancement for the reasons I listed - it's an ironic emergent behavior but it is one that repeats all the time so people should know about it. Nassim Taleb calls it antifragile but it has occurred throughout history. You make an enemy stronger by attacking them, which is not to say don't attack your enemies, just be more careful about it.
I said I think we'll lose and even if we win the result will still be calamitous. I think people have rose tinted glasses of the 1950s and think that a war time economy and a military victory will bring that back. It wont.

In 10 years time, China may come up with a production of 10-7nm. It may or may not be profitable to mass produce. By then, they will be 12 years into their 25 years Great Depression. Their real estate and stock market will still be in the toilet, and their demographics will go down 200-300m. They will have 30% of their population over 65. It would be iffy to say at that point whether the Chinese government has enough money, besides addressing their enormous debt, to keep pouring into a losing enterprise like this.
The western technology companies will be somewhere way way farther along/bigger by then - look at spacex flight this week for comparison at how fast western technologies move.

SMIC is doing volume production at 7nm now.
So what if China has 7nm chips now, there's no Huawei it can make them 'at scale' https://www.theregister.com/2023/09/19/huaweis_advanced_chip...
I'm not sure that assertion by the US Commerce Secretary is holding up a months later. Apparently "Huawei has seen a resurgence in its premium smartphone sales since it released its Mate 60 series" (the phone model in question): https://www.reuters.com/technology/apples-china-iphone-sales...
What products contain that 7nm?
The latest Huawei phones and the locally produced version of the Huawei Ascend AI accelerator.
Can you be more specific? Their flagship is Snapdragon and their top phone with their own SoC design is Kirin, both made by TSMC.
The AI acellerator is Huawei Ascend 910B which is comparable to the NVDIA A100. And the latest Kirin chips are made by SMIC. The sales of the phones are in the millions and it is the main reason for Apple's declining sales in China.
I found Mate 60 Pro for just over $1000 with Kirin 9000S. Still a question of volume, but seems legit.
Can anyone with more hardware insight tell me if the brunt of this story is actually true, and how related to this chip AMD's actions were?

Different company! Loongson runs their own MIPS based ISA which is self-developed.
IIRC that company is called Zhaoxin, which has had mild success getting ~Zen 2 performance domestically.
I'm not to sure why WSJ is citing that as a 'national security issue', everything related to China seems to be called that now.

Yeah it's American vs Chinese empire stuff at this point. New cold war and all that.
It is funny, you could take articles from the 1980's about Japan taking over Americas grip on technology, swap Japan to China and they would read almost the same to what we are seeing today.
Yes, there are some different key details but the parallels on the messaging is neat to see.

How much do these CPUs cost? There'll be international buyers if they can beat Intel and AMD in terms of price to performance ratio, even if the chips are slower and consume more power. For general home and business computing Zen 1 performance is more than adequate especially since these are designed for Linux.
I guess it's not easy to even get your hands on it. Likely pretty low volume.
What kills it for the home and small business use is that it's MIPS. Just not worth saving 50 or so dollars of AMD / Intel premium for this trouble. As I understand, this CPU doesn't have an iGPU which makes it an even worse deal.

2 minor gripes!
1. Not MIPS, LoongISA, there are working Binary translators already, and they're commobly used in government office work!
2. They do have an iGPU, refer to Geekerwan's video!
Otherwise agree though, they're unlikely to go international at this point!

It seems Linux is going to win the desktop wars in China.
Windows is clearly never going to be ported to this oddball MIPS architecture so their stack will all be dependence on open source but sadly they will not return the favor by releasing their source or maybe my perception of China open source is biased.

That's not quite true and your bias is showing. The company behind Loongarch is reasonably friendly to FOSS and most of their LA64 changes (to Linux, llvm, binutils, gcc, etc) are upstreamed in a timely fashion. As for the chipset, kernel drivers are all open source although not all have been accepted upstream. I have personally been maintaining the out-of-tree Linux drm driver for their onboard gpu chip and it's available on github https://github.com/cl91/linux/tree/gsgpu-devel. If you have a barebone 3A6000+7A2000 setup, as far as I know the only closed source component needed is their userspace mesa driver for the onboard gpu.

+1 while I don't have any idea this deep in hardware engineering, in normal appdev Chinese open source contributions are well known and there's a whole class of up and coming apps which are great, just not internationalized well enough for others to use yet
The company behind Loongson has been very FOSS friendly. There was a 2009 Google Summer of Code project porting Debian (or was it Gentoo?) to Loongson CPU. https://opensource.googleblog.com/2009/05/2009-google-summer...
The CPU does supposedly have instruction set extensions for faster execution of binary code translated from x86, ARM and RISC-V.
They think that it would be sufficient for running Windows/x86 apps at near-native speed in QEMU.
No ISA spec has been published. A few research articles are available from Chinese universities but most are only available in Chinese.

At this rate, China is gonna be able to catch up with Intel/AMD soon?
See excellent article. The 3A6000 is Loongson’s best and newest and performs between the level of Zen (GloFo 14-12nm) and Zen 2 (TSMC 7nm) but limited to four cores.
A lot depends on the cost to produce that chip, whether Loongson can scale below 14-12nm they’re using currently (EUV without ASML?), and what development resources Loongson can deploy for their next microarchitecture revisions, which aren’t discussed here.

Which is fine. For most applications, it's the order of magnitude of performance that matters. Not +10..30% or say, Zen 3 vs. Zen 2 (although gamers & AMD/Intel execs will argue otherwise).
Machines with >10y old cpu's are still perfectly useable for (most) everyday tasks, as long as the software support is there. Especially when coupled with enough RAM, decent gpu, SSD etc.
On the way from "pointless museum piece" to "latest & greatest", this cpu is 9/10s there.

Finally a sound voice in this merry go round of one-upping. Totally agree. The funny thing is, if people paid half as much attention to optimizing the bloat crap they build, instead of drooling over 10% cpu gains, you’d see a much bigger improvements. Obviously it depends on the domain, but everything I’ve come across (except core tech like SQLite etc) have huge overhead in both memory and cpu that could easily be optimized if someone paid attention.
Like the json parsing issue with gta online, that’s a perfect yet egregious example of software practices today.

I think you missed the "limited to 4 cores" part. Zen 2 has up to 64, which considering it is also slower per core makes it 20 times slower. If like me you count 2x as order of magnitude, that's 4+ orders of magnitude away.
They are certainly accelerating. I think the consensus is that it is within fabrication there is a "chokepoint".
In terms of design, China has world class companies. However in terms of fabrication and especially semiconductor manufacturing equipment, they are still somewhat behind.
Also x86 is very sticky - it is going to take them a decade to get rid of that.

And not just companies. This is currently the world's top open-source RISC-V development https://github.com/OpenXiangShan coming from the Chinese Academy of Science.
(Whether China will remain investing in RISC-V, given that the US government has started to pressure US RISC-V development to limit their involvement with China is another question.)

Interestingly, they've got binary translators for both ARM and x86 which were demoed in Geekerwan's video. Apparently, they're apparently donating a compilation farm for a Debian repository.
Definetly interesting to see how Lithography will develop independently in China, and if it will ever pass the EUV chokepoint.
A decade or two isn't a long time, politically.
used to be MIPS based, is it still the case, could not find the info at that page.
The chip uses LoongSon's own "LoongArch" ISA. They moved away from MIPS supposedly because of fears of licensing issues.
It is very much like the last revision of MIPS but modernised a bit: No more branch delay slot. No HI/LO registers. The arithmetic ops that trapped on overflow are also gone.
There are published docs only for the scalar ISA subset: https://loongson.github.io/LoongArch-Documentation/README-EN...
Chips and Cheese has an analysis of the "LSX" and "LASX" SIMD sets. LSX is very much like MIPS's MSA. LASX is extended to 256 bits: https://chipsandcheese.com/2023/02/26/loongsons-lsx-and-lasx...

MIPS ISA? Is this a problem in practice in 2024?
Are there any comparable CPUs made in Europe?
x86_64? Seriously?
I would understand if that would be for legacy support, like x86_64 decoded to risc-v.

The article missed out on context. The chip runs LoongSon's own "LoongArch" ISA which they had developed out of MIPS'. Chips and Cheeses test programs are written in that ISA. There are other articles on the site that tell more about it.
LoongSon does however supposedly have a instruction set extension for running binary-translated x86 code faster (and ARM and RISC-V), but they have not published much about it.

Since RISC-V has also its roots in mips, maybe loongson should move to RISC-V for good with a x86/arm hardware translater.
All that to run binary distributed x86 apps...
All that to run binary distributed x86 apps...
Today I agree that it would make much sense for LoongSon to jump on the RISC-V bandwagon.
However, designing a CPU takes years. Back when they transitioned from MIPS to LoongArch, RISC-V wasn't mature enough to have all the functionality that their MIPS cores did. There was no ratified Bitmanip extension and it was unclear what kind of vector extension that it would get.

Unfortunately, RISCV is really a mess right now, the Vector extensions are horrible.
Amusingly, LoongArch has better Linux support than RISCV right now too...
Would've definetly been nice to see them adopt RISCV though. ISAs are fragmented enough as is.
> the Vector extensions are horrible
How so?
How so?
They're horribly fragmented (there's many ISA extensions that accomplish the same thing from different companies), and thus a headache to deal with for any compiler (which is why the compiler support sucks).
There is one standard vector extension, and one company that released two chips with a non standard pre ratification version of the extension.
It was released almost two years before the first rvv 1.0 hardware became available at the end of last year. Without out it, we wouldn't have had any hardware at all.
rvv 1.0 has quite good upstream compiler support already, and before that the t-head had custom compilers that supported their rvv 0.7.1 version of the vector extension.
Now upstream gcc supports it as an alternative codegen target as well, so you can write rvv 1.0 vector instrinsics and compile those to the thead rvv 0.7.1 implementation.
I'm not aware of any company that plans to release a non rvv 1.0 rvv implementation.

Each time somebody is spitting on risc-v vector extension, it is the same false argument of fragmentation, and each time somebody fixes it with the real truth (pre-ratification of some vendors).
Arm/x86 fan boys?
Arm/x86 fan boys?
"Real truth" and "fan boys"? Let's have some facts: there are indeed a boatload of extensions, though perhaps not (yet) to the V extension itself.
T-HEAD [1], Ventana's ternary op [2], Sifive also has a couple [3], including "Xsfvfwmaccqqq", one of at least four completely different matmul variants.
In particular for the latter, I would say fragmentation is an absolutely valid concern at the moment.

T-Head also has their own matmul extensions, but t-head, SiFive, Andes, Rivos, IMB, ... have all people working on the risc-v integrated matrix extension spec.
The vendors presented their own matmul extensions, but none of them solve all problems that the integrated matrix extension should solve. Most importantly binary compatibility across vector lengths. The last to meeting presented alternatives that would satisfy that requirement. It will however take some time to decide on and experiment with the best design.
I agree that this can turn out messy, so far I haven't seen anyone, outside of vendor libraries, use the t-head or SiFive matmul extensions in open source code.
Ventanas ternary op and similar will hopefuly consolidate on the cmov extension.

I agree the situation changes if there is a single new spec, this is why I wrote "at the moment". Do you have any insight on when it's finished/ widely available? I'd guess two years?
Indeed, vendor extensions are no fragmentation of the ratified and frozen extensions.
The real signficant and annoying fragmentation is 32/64 bits (accutely painful on x86).

hm, from my point of view, "here are 4+ different ways to do it, depending on which CPU you are running on" sure sounds like fragmentation.
Perhaps embedded systems engineers see things differently if they know exactly what CPU they are going to target.
32/64 bits? It's been years since we dropped support for 32-bit x86 :)
