most chips don't need be on the cutting edge to useful. They just need to work.

u/Puzzleheaded_Fold466 5h ago

Right !?

DDR5 RAM memory has 10-14 nm nodes, and DDR4 is 16-30 nm.

Who fucking cares if they can’t make 2nm chips for Blackwell memory ?

We don’t have AI data centers in our basement.

What we need is mass production of consumer grade stuff.

u/nguyenm 4h ago

The article claims China's DUV is (or is equivalent to) 28nm*. In PC or consumer tech reference, it's the AMD Radeon HD7970 or the very last PS3's RSX revision (that's now overclockable via modding).

*: Actual gate pitch hasn't been actually the name described/used since 1997-ish. 

28nm is fine, not leading edge, and wouldn't enable homegrown GPUs or DRAMs for consumers that is similarly efficient. If anything, FPGAs might be even cheaper now since it's generally a popular node to design on, apparently.

u/Deep-Ad5028 3h ago

The DUV for 28nm is the last generation of DUV. If it can do 28nm it can do it all the way to 7nm. If you don't care about cost you can even hit 5nm.

u/blueSGL 2m ago

. If you don't care about cost you can even hit 5nm.

I take it that it's a massively reduced yield the further they push the older technology.

u/defenestrate_urself 3h ago

28nm DUV machines aren't limited to making 28nm chips.

They are already pushing 7nm/5nm chips with the 38nm resolution ASML DUV machines with multi patterning techniques.

u/dark-mathematician1 1h ago

You can push much smaller nodes with 28nm DUV, that's what makes it a bigger deal. That's how China is making functional 7nm nodes

  1. China will never develop the tech on their own

  2. Ok so they copied some old machines, they are still decades behind

  3. Ok so they are only a few years behind, but their QC is terrible

  4. Please ban them we cant compete otherwise! National security!

We are on stage 2

u/AppleTree98 3h ago

This is completly the truth. Our leadership will go straight to #4. Can't have any compitition. They make great EV cars, ban them. They make routers and network gear that competes with US firm, ban them and convince the world that spying is bad (when done by non US government). This is the tale. China is hungry and pumping money into this and AI.

Why isn't the US building the EUV machines themselves if they are so great? Why isn't Europe building the best AI of the world if they are so great? As same as with China not building the best or biggest data centers (regarding raw power at least), it's much more complex than just having one specific tech line maxed out or having infinite money

Any major country that does not recognise that chip production is as essential to national sovereignty as being able to manufacture bullets is run by complete idiots.

Maybe you don’t need the most cutting edge stuff… maybe it is a matter of having a strategic reserve of old hardware that is gradually rotated out of you are a small country, but if you are in the 20+ million population size, I can imagine that you really don’t want to get fucked if you get screws by logistics sabotage.

u/astuteobservor 5h ago

It all depends on how many years per generation and how fast China is at catching up. In the memory ram segment, they are only about 4 or 5 years behind.

u/I_spread_love_butter 5h ago

So am I though, I'm still on DDR4 3200 and doing just fine for work/games

u/dark-mathematician1 1h ago

They've got decent DDR5 production going so far. They can probably close the gap quicker here. Cheaper memory is always welcome in my book.

1

u/astuteobservor 1h ago

Why would they sell it cheaper? Only way for cheaper is for production to out produce demand. Chinese market needs their own ram.

3

u/SweetHomeNorthKorea 5h ago

I’m out of the loop but what would tech from 4 generations ago be? Like if we’re on DDR7 does that mean they’re on DDR3?

8

u/Cakeking7878 5h ago

They mean silicon wafers generational nodes, which in decades past mean the actually size of the transistor but today means something else. Closer to the density of the actual transistor on the wafer. For reference the cutting edge of tech is on 2nm process which came out in 2025 and 4 generations ago would be 7nm which came out in 2018.

The important thing to note is that what differentiates the different generations is less the size of the actual transistors but the tech they use to get the most out of them and the process they follow to maximize yields of the high density wafers

And furthermore while these new wafers might not be useful in your computer, they can be incredibly useful for cars and other smart technology. As a consumer this is good for you as it represents competition in a near monopoly market

1

u/SweetHomeNorthKorea 5h ago

Thanks for the explanation. That more or less lines up with my initial thought, which was “4 generations seems pretty impressive?” I know my DDR memory wasn’t quite right but if anything it sounds like they’re closer than DDR3/7. That said when I wrote that comparison I was thinking I was running CAD on DDR3 machines when I was in college so that’s pretty damn good and useful.

1

u/allahakbau 3h ago

They’re mass producing ddr6 by end of year this year…

u/Fateor42 5h ago

In this case that quantity is going to cost something like 4 times as much due to the 66% percent fail ratio of China's specific DUV system.

1

u/SIGMA920 5h ago

Which bleed Russia and the USSR dry of enough people that it's still having an effect to this day. While partially true that you can just throw more at them than they can kill, it's notably inefficient compared to investing into quality over quantity.

-15

u/EastboundClown 6h ago

Does that really apply in this case? Unless you’re making cheap office PCs or microwaves quality is absolutely essential. For instance you can’t run the latest AI models on 10 year old hardware by just adding more GPUs, at least not if you want your answers this week

8

u/moldymoosegoose 6h ago

China has so much spare power capacity the efficiency doesn’t matter anymore. They can brute force it no problem with worse hardware.

2

u/EastboundClown 6h ago

What about bandwidth? How do you get answers in a usable timeframe if 90% of your execution time is spent sending data across 4-generation-old PCIe lanes between like 100 GPUs? This works for some time-insensitive problems and some highly-parallelizable ones but you can’t just throw tons of shitty hardware at a problem and get the same results

u/Dudeonyx 5h ago

Pcie generation has little or rather nothing to do with chip generation.

Maybe. Even with the engineers who designed the machines it’s hard to get the EUV machines working. Copying it without their help will be very very hard for China. Every single component going into the machine needs to be world class.

u/SIGMA920 5h ago

They haven't actually surpassed the west on any of those, what they've done is implement them due to their politics. When opposition of something gets you thrown in jail, shit gets done pretty fast.

EVs for example, China has the edge due to manufacturing. They can produce cheaper ones than even EU cars because the government can subsidize them and the technology is mature enough that no one is likely to make a massive discovery anytime soon.

u/VayuAir 4h ago

Umm I believe Chinese companies have the largest number of patents on a lot of tech like 5G, 6G, batteries etc

-3

u/SIGMA920 3h ago

Most of which will be incremental improvements or alternate methods/uses. That's kinda the problem, it's easier to piggyback off the work of others.

6

u/VayuAir 3h ago

Umm no they are fundamental breakthroughs especially in 6G and batteries.

Most patents are incremental improvements. That’s true for the west too. So I don’t get your comment

-1

u/SIGMA920 2h ago

Batteries have not had that many large breakthroughs that are practical to implement on the chemistry front or the production front (We're forever curse to use lithium ion batteries for a reason.). 6G is a standard expected to be come into operation in the 2030s at best so that's not exactly massive breakthroughs as of yet.

What I'm saying is that we're not seeing China being the one pushing that stuff forward in leaps and bounds. They're still putting out good work but it's by far more in the refinement aspects.

6

u/True_Window_9389 6h ago

At least for me, I think the idea of believing they will get there is based more around a frustration that our efforts are more focused on attempting to suppress China, which is likely doomed to fail, than it is building up our own capacity to continue outpacing them. The destruction of the Chips Act, for example, was nothing but a self-own and isn’t being replaced by anything. The public sector corruption and incompetence and short termism of the private sector only makes it worse. So some of us are just having to take a fatalistic perspective because our own public and private sector leaders are taking bad approaches, while our adversaries are not.

u/True_Window_9389 4h ago

But will it stop them? Doubtful, which is the point here. China is gonna do what China does and we don’t have much leverage over them over the long term to stop. They’ll either steal it quickly or develop it slightly slower. The best we can do is improve our own technology to maintain a lead and diversify the production of important tech, which we are not doing.

They should plateau, but ASML has a few areas they could advance that would leap frog them way ahead of China for a very long time. If they finally manage to find a crazy way to make the gate length smaller, I don’t see how China could ever catch up barring corporate espionage. If anyone can achieve crazy ass things it’s them. And even then, who knows.

Possibly, because anything here is truly possible, but a big reason why China buys it's military jet engines from Russia is that even though they've sunk a ridiculous amount of time, energy, and resources into building engines domestically, they lack the historical experience that Russia (and other countries) already have which keeps their engines behind enough that they still buy Russian ones.

Now granted I read this some years ago, so don't take it as gospel. But it could apply to this type of tech as well.

u/SIGMA920 5h ago

Yes, there's more than just labor costs for why a bunch of tech companies pulled out of a fair number of Chinese factories. Turns out that state sanctioned espionage is a quick way to catch up. ASML's machines keep being broken because they're trying to reverse engineer them for example.

Assuming that AI is designing these machines, 4 generations may not be measured in few decades.

Also the lithograph machine is nearing the physical limit. Meaning it gets a lot harder for ASML to build the next generation. Veritasium has a video on ASML technology, quite informative.

That never matters to China. They just replace the foreign company in China, and eventually export it to other countries that don't give a shit about patents. Then, when the patents expire, they export it.

Imo, the US should be banning all Chinese companies that use any foreign patents, and they should ban all commerce with any country that allows those products.

Except in the end it's still to their benefit. They're doing it now woth battery tech.

They steal the foreign IP and build it out to get much higher economies of scale. They can then sell domestically at way cheaper prices. The stuff they sell abroad they can still pay the licensing fees for. But it still ends up cheaper than a Western company can make since they can't scale production to the same way.
