Also, who decides which entities are adversaries? I don't personally consider "China" my adversary. As an American who has to deal with US companies, many of them are far more antagonistic to me than a foreign country 10K km away. If "China" decides it doesn't like me, my life really isn't going to change much. If my electric company decides it doesn't like me, I'm in big trouble.

> I don't personally consider "China" my adversary They're not an adversary in the same way that a guy demanding your wallet at knifepoint is, or a company able to cut off your electricity is. China is an adversary in the sense that they're a totalitarian government, who, by the nature of that system, cannot brook any sort of opposition to their ideology, plans, or desires. All within the state, none without. That so…

> That sort of system cannot exist in harmony with other systems for any extended length of time

When you mark the scoresheet according to actual number of invasions, our capitalist liberal democracy has performed much worse than their mixed-economy authoritarian technocracy.

This is a lot of needlessly "ideology vibes"-based judgment on a matter where plenty of actual evidence (history, geopolitical incentives, culture) is readily available.

This thread is the perfect example of useful idiots with astroturfing. This is a CPU core designed by UK company (and owned by Japanese) made in Taiwan on equipment made in EU (with non trivial USA components). Xiaomi here is the easiest to replace in this chain (and the Chinese have very much tried to replace any of the others, failing for now). Yet they are angling for a huge PR win.

ARM is merely an IP portfolio licensing company. They don't really design or build anything. And everyone uses TSMC (who uses ASML). The primary design is still being done by Xiaomi, that's the most unique part of this build. Stop downplaying how big of an achievement this is.

Below is some additional detail about the processor. Like the parent comment notes, ARM licenses IP of an ISA or core designs (see ARM C1-Ultra cores [0]), licensees like Qualcomm then make specific SoC for different use-cases.

  Xiaomi has made the XRING 03 boast a larger die size than the XRING 01, 
  measuring 133mm² compared to its predecessor’s 109mm² dimensions This change 
  was deemed necessary as the flagship SoC features 16MB of SLC cache, not to 
  mention a new “6 + 4” CPU cluster that comprises two ARM C1-Ultra cores 
  running at 4.35GHz, four C1-Premium cores operating at 3.68GHz and lastly, 
  four C1-Pro cores running at 3.15GHz. [1]

This is still an ARM C1-Ultra. Same one used in Mediatek dimensity 9500, which also got more than 4000 points in GB6 lab test. But actual results inside phone with smartphone cooling and wattage requirement became close to 3300. But perhaps the most important thing, Xiaomi is now able to make chip similar to Mediatek. They are the third largest Smartphone manufacturer by shipment volume. And they are still growing. T…

Now imagine if they actually provided a good support for Windows and Linux for those chips and started selling it to OEMs for Desktop/Laptop use.

I wouldn't be surprised if Xiaomi intend to use this for their laptops with Windows 11 once the software ecosystem matures. Which both ARM and Qualcomm are working on. But I still believe in terms of PC usage it is all going to be Nvidia.

I think it's great that the Chinese are catching up and can compete directly with the incumbents. The GPU space I find really exciting with several new IPs out there that aren't quite ready for primetime, but still fascinating.

Also, here's to hoping we get some relatively competitive Chinese DRAM flooding the consumer market someday soon.

This is nothing. China is about to start doing their own 5nm. When they roll out their own silicon at scale, I don't think there's catching up, nobody can match their manufacturing capabilities. Not even close.

They are already doing 5nm with multi-patterning DUV. But that's not the same as EUV machines. It is not nearly the same scale of production (with yields as low as 20%). They are still a few years away from indigenous EUV. Though I have to admit the shenzhen breakthrough was pretty impressive

"Looking now"? Is this something they publicize for some unknowable reason?

I don’t want to get bogged down in a source dispute - this is very easy to search and/but I only spent about 60s on it. I am hardly an expert. Feel free to look it up as well and tell me how I am entirely wrong. This was a combination of AI responses + thumbing through the sources linked to make sure it wasn’t invented whole cloth. I do not think they are selling well. That seems to be the consensus here.

I don't think they are selling well, either. I was wondering at your source since it would be very atypical for any company to give any numbers at all, let alone a company that's so outwardly sketchy, let alone numbers like "This is the number of orders we have standing open despite being actively in production." This is the exact kind of thing I would not expect to be easy to search, and it'd be ripe for AI hallucination.

The only numbers I can find in a quick search of my own are the leaked numbers stating 30,000 orders placed from 10,000 customers, with nothing said about shipped orders.

This is what will happen when a hegemon realizes their power and elects someone scrupulous. That's why it's important to be the hegemon.

Meanwhile look at the southchina sea shenanigans and the behavior of Chinese fishing fleets all over the world.

Or allowed you to run Linux on their phone. We can only dream.

They do allow to unlock their bootloaders, which is rather rare, which in turn allows to run Linux. Seeing as Chins just migrates their entire administration to Linux, it's not far fetched to assume they'll support Linux on their laptops very soon.

Caveat on the unlocking of bootloader.

It is very much harder to do now. There is a lot of friction introduced now to it.

No. Chinese dumpers undercutting everyone else and destroying the competition is never good.
