all for profit companies are greedy by their nature, but US companies are on a different level because you can 'buy' the government by lobbying or supporting their election campaigns or break the law and eventually make sure law is changed to fit your business (e.g. first taxi medallions adjusted the law for themselves, and then Uber) Same is very difficult to do in China (look what happened to Jack Ma) or in Europe,…

Thinking there's no corruption in China because Jack Ma got sent to a dungeon for being too mouthy is actually comical

there's less corruption than in the US nowadays.

Were I to guess > The biggest cores on the the Xring O3 are the C1-Ultra. C1-Ultra really powerful cores. They support SME2 (Scalable Matrix Extension 2) for matrix/AI acceleration, SVE2 for data parallelism (SIMD). This is where the magic is happening (I believe). They have these ultra cores with additional extensions which they are pinning the benchmarks to. Realistically, that sort of thing isn't useful as non-hom…

All 10 cores support the same extensions. It’s silly to implement an SoC any other way, and it’s been a decade since someone has last made that mistake.

It's been a long time since anyone tried to actually ship a chip with different instruction set support enabled across its cores, but Intel has spent the past several years shipping consumer parts where they had to disable some features (AVX-512) on their P-cores to bring them down to the level of what their E-cores support, because they didn't plan ahead for doing a heterogeneous chip with those two microarchitectures. Toggling off some instructions in microcode for some cores is quite different from having two microarchitectures that are each designed to implement the same instruction set but with different performance and power characteristics.

One of the (many) areas in which China is doing great is industrial robotics. Not the fancy dancing dogs, but robots that replace workers in factories.

That why I said it either goes to robots or it goes away. Can the current robots replace something like this? I don't think right now but maybe they figure it out. [1]: https://www.youtube.com/watch?v=yFYxSX6xP2U

I love this, really, competition on a global scale is good for us, bad for greedy US corporations. For example, I consider Meta as bigger threat to society, than Xiaomi, DeepSeek, z.ai and other top Chinese companies (haven't used Chinese social media, so can't comment about its content)

I hate China’s form of government for everything except rapid development. I don’t trust as single one of their companies.

Xiaomi also make amazing cars. "WSJ I Test Drove a Chinese EV. Now I Don't Want to Buy American Cars Anymore. https://www.wsj.com/tech/personal-tech/chinese-ev-test-drive... "

They have 5 min full EV charging while I have to twiddle my thumbs for 30 minutes at every charge stop. What a shit administration we currently have.

Yes and no. Having more competition in the space is excellent news. However I am sad that the world interdependence is eroding as most other countries seem to sit on their hands and happily outsource every bit of manufacturing to a single country.

I think Western people still call this situation “outsourcing” when in reality what is happening is that China is better at manufacturing than everyone else, and they’re starting to be better than everyone else at design and engineering, too. When we buy software from Silicon Valley or a nice Mercedes Benz from Germany we don’t use this same language “outsourcing.” Colloquially, outsourcing implies low quality or che…

> I think Western people still call this situation “outsourcing” when in reality what is happening is that China is better at manufacturing than everyone else, and they’re starting to be better than everyone else at design and engineering, too.

The media to this day portrays China as if it was 80s. Yes, at that time it was an open-air manufacturing plant. You can run rudimentary floor operations with high school educated workers, but you still need trained engineers and managers to run the operations. Exporting engineers quickly became impractical, which led to local engineers getting trained. At some point the training became the bottleneck so local educators were trained. And so on.

Over the years, China has built the entire industrial pipeline: all the way from education and vocational training, to scientific research, to local engineering houses. Remember, the people who built Shenzen are now retired. Or to put it into perspective, China is currently at roughly similar age of industrial boom as post-WWII USA was in... the late 90s - early 00s.

"The West" had a head start with regards to IP and China is indeed fighting an uphill battle there, but they have a huge domestic market to grow the companies out. The proud "Designed in X, made in China" things are being replaced with white-label "made in China", where "designed in China" is implied.

Do you have a robot vacuum? It's probably Roborock / Dreame / Ecovacs, not even some western branding.

China and Taiwan are considered one country, even according to US https://www.congress.gov/crs-product/IF12503 How do you make one country into one country? It's already one country and is treated as such by even countries that consider China an adversary

> China and Taiwan are considered one country, even according to US Your link does not say what you think it does. My guess is you read the first sentence and saw "one-China police" and stopped. But the US's one-China policy is not the same thing as China's one-China principle. The US's one-China policy is that (continental) China is a single China governed by the PRC. It's silent on Taiwan. But, considering the laws…

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…

The age old problem of mobile chips have brilliant performance for about 15 seconds until they thermal throttle. If you are just using apps, 15 seconds is more than enough to launch and setup an app, for anything more it will be down graded a little. Still dang impressive but the form factor becomes the limiting factor.

Imagine they make a MacBook Neo Xiaomi version. That would solve the form factor problem.

Not at all. I specifically bought a MacBook Air M4, first Mac product in my life, for its fantastic performance in a passively cooled notebook. I have zero loyalty to Apple and usually use Windows. If someone else starts beating them perf wise, I'll happily switch again.

The air m4 is really the best sub-thousand-dollar laptop.

I was surprised when I bought my 'cheap, crappy' 2024 M3 Air ($1.3K) and it ran circles around my top-of-line last Intel MBP ($4.6K).
