Anyone can make a fast CPU, but is it also a safe and secure CPU? Or does it have architectural defects as a consequence of the race to be fast? See eg LoongLeak and the Loongson processor: https://www.usenix.org/conference/usenixsecurity26/presentat...

Xiaomi are implementing ARM cores on an ARM ISA so any architectural defects would also affect other ARM processors.

There are side channels available, they have licenced IP blocks, not a whole CPU. All that logic for the cache and interconnect.

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 feel you're trying too hard to make believe this is somehow unexpected or unnoticed. The fact that subcontracting work to external companies acts as an investment on said companies to develop skills and competences is something that is known since always. The argument that the reigning VC mentality is that this investment is an acceptable tradeoff due to reasons such as these investments being limited to non-critical business concerns.

The GPU performance is insane too, approaches M5 results at ~20W. Of course it will be in Android phones so it will be throttle hard past 4W and will have terrible drivers. I wish phones moved to HPB packaging and active cooling so we could have sustained 10W and use them as light workstations.

I’m not sure I follow why the performance is “Insane” This is a M5 level chip that runs slightly within a ballpark of M5 wattage (afaik M5 is between 15W max on an iPad and 30W max CPU+GPU on a cooled Mac) This is running in a thermally unconstrained bench setup and has potentially worse power consumption with what will be lower than previous gen performance when this and the alleged M6 are truly out.

So tired of people on HN calling you out for being excited about tech.

It gets M5-level numbers at 12-14W.

It gets about 30% better perf than the A19 Pro at equal wattage on the whole 4W - 8W range.

So no it's not worse power consumption than prev gen. This is ARM's stock GPU having finally caught up and being competitive with Apple and Qualcomm's mobile GPUs.

This is insane to me. Stay cynical if you want, I have the right to be excited about it.

I've lived in Taiwan for a large part of my life. They would lose all of TSMC if they do any military actions. It's not the fact that the CCP thinks that they can make Taiwan and China a country, it's the the fact that most of China does in fact consider them as one country. Taiwan is ready to defend themselves, but are very happy keeping their relationship with China the way it is.

> I've lived in Taiwan for a large part of my life.

> _China doesn't need to invade Taiwan._

All your points consider what China can do but not how others would respond. Blocking Taiwan when the whole AI economy is running on it will invoke lots of countries to go up in arms. There was a quote from US military that it'd cost less to fight than watch Taiwan fall (invasion or not).

> 4. China is close to producing industry-grade EUV

No where near close. At least not production grade at massive scale.

> * Establish a total naval and air blockade of Taiwan using their fleets stationed in Ningbo and Zhanjiang.

Doesn't work. If they do that the US, JP and others can also blockade around Shanghai, Hong Kong and the other ports.

> They won't need TSMC soon

Taiwan is not just TSMC. There are thousands to millions of things involving Taiwan you're likely not aware of and they might not even be AI or semi related.

Why would China care if Taiwan blows up its fabs? The talent is still there, so they could rebuild, or recruit the talent to work for Chinese mainland fabs instead?

> The talent is still there, so they could rebuild, or recruit the talent to work for Chinese mainland fabs instead? Would you voluntarily work in a country that invaded and taken over yours? Would you ask the same about Russia recruiting Ukrainians?

Not everyone is affected by propaganda, either US/Taiwanese or Chinese one.

Some are.

Some people also want to feed their families and not be unemployed.

P.S. A large number of Ukrainians moved to Russia. Including the ones who wanted to reunite with their relatives. Taiwanese have a lot of relatives on the mainland as well.

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... "

There was a lot of hype about the SU7. They killed it with pre-orders. But their target for the year at 550K isn't gonna happen as they're sold about a 180k so far this year.

Due to lack of demand or lack of production capacity?

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.

There’s still one mystery for me. I’m now at the iPhone 16. The performance of those chips with 8GB in non throttled environment (Neo..) can run as a fully performant macOS. Yet, as a phone I don’t feel upgraded performance since my SE 1st gen days. Sometimes I get stuttering, basic browsing can get the device pretty warm, sometime camera lags to launch. My usage profile didn’t change much over the years. So I can on…

Devs pay attention to, and optimise, anything that is painfully slow in their test environment. That’s why we need to test stuff on slow hardware.

US backed off last year when there were talks about protecting Taiwan. They pulled Patriot missiles from Taiwan and South Korea too.

China and Japan have a beef. Considering the atrocities Japan did in China, the conversation won't be friendly.

None of these are good for Taiwan, during the times when its political system is failing.

> No where near close. At least not production grade at massive scale.

It looks like you have knowledge of the status of that super-secret government project. Can you share some details then?

> Doesn't work. If they do that the US, JP and others can also blockade around Shanghai, Hong Kong and the other ports.

US cannot blockade Hormuz, as we've seen. JP cannot do that with their current constitution unless they change it (the current government is on the road to it, though).

What we've also seen is that Chinese fishing fleet had a military blockade exercise [0].

> Taiwan is not just TSMC. There are thousands to millions of things involving Taiwan you're likely not aware of and they might not even be AI or semi related.

All is around semiconductors.

The CEO of Ford directly said if Chinese EVs are allowed into the US it will be the end of US auto manufacturing. They know they are inferior, and choose not to compete, just lobby for more regulations to keep competitors out. Free market, haha.

China is nowhere near “free market”. Their EV sector received more government subsidies in the last 15 years than the entire U.S. automobile market since inception. The total subsidies make up half of the market cap of their entire EV industry. 250 billion in EV subsidies from China. 10 billion by the U.S.

If China government kickstarted their EV sector (along many others) and enabled them to be competitive, strong and dominating.

That means the Chinese government is doing a really good job.

I really hate this argument where every government across the globe have to basically be a drag which sucks the life out of an economy and wastes extracted resources (taxes) on bullshit instead of putting them to good use.

This is what winning looks like fellas, and you're just losing. Get used to it as there's only going to be more of this.
