CCP is not threatening taiwan because it might go for independence. it is _ALL_ about kicking the US out of the west Pacific. because of that, it is never about what people in Taiwan believe/say/do.

Anyway, Xi made that a test of the legitimacy of the CCP, in some very public statements. So, no, it's not about kicking the US out of the west Pacific. It's about Taiwan, and it's because if they don't, the CCP is illegitimate, by Xi's own w…

By 2023 Xi ordered the Chinese military to be ready to invade Taiwan by 2027.

But that doesn't mean they plan to invade Taiwan by then. One common reading of it is that it was a plan to build up the military to that state with a definite goal date (in the same way the "600 ship navy" plan had a goal date).

China is doing it today — uighurs are actively erased bit by bit. > Look at India, before British colonization they accounted for almost 25% GDP of the world (~1700s), now it is around 3-4% This statement is rooted in “zero sum” logic, and based on the assumption that without colonization India should have sta…

Can you read what I have written? if not, let me copy what I wrote earlier here:

> I am fine with lesser of 2 evils

> But it obviously has its own problems (e.g. how competitive is the life in China for kids and so on), I am not saying China is perfect

I am not saying China is good, I am saying it is lesser of 2 evils with much less negative impact to the lives of human beings around the world, in my opinion.

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.

While the other comments are correct to point out that majority of mobile workloads are rush to completion, many users (especially in China) still do a lot of heavy gaming on their phones. This is exactly why the newer SoCs are so interesting- that they can deliver more performance for the same power consumption. (Directly increasing run time and decreasing heating)

> many users (especially in China) still do a lot of heavy gaming on their phones

I think most children prefer to play on phones these days. Mobile gaming is huge. To the point where game loops on high-end games are optimized around thermal throttling.

> Sure, but not the way West conducted it, by going and killing generations of people. But they did. Look at Xinjiang, Tibet, and the history of Manchuria, among others. They did it to themselves as well, like most backwards dictatorship. And "the West” does not really do genocide anymore, either. This is more a consequence of it being a terrible strategy than Chinese benevolence (or anyone’s, really). At some point…

> And "the West” does not really do genocide anymore, either

Don't want to get into the definition of genocide, but sure, you can think of whatever you want, but facts are different (https://en.wikipedia.org/wiki/List_of_genocides):

    * Gaza genocide (supported and enabled by West)
    * Bosnian genocide
    * Holocaust
Not classified as genocide but almost similar or even larger impact:

    * Vietnam war
    * Afghanistan
    * Iraq
    * Libya
    * endless sanctions and blockade against Cuban people
> “The West” is not a monolith. It’s made of several countries

some wars on the list were joint operations between US, Britain and NATO, for others you can read this 20 page wikipedia article: https://en.wikipedia.org/wiki/List_of_wars_involving_the_Uni...

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. Sounds like you've been fed the US anti-China propaganda for the large part of your life as well. _China doesn't need to invade Taiwan_ 1. 50%+ of Taiwan's workforce are white-collar workers [0]. 2. There are 3-4 major underwater internet communication hubs in Taiwan [1]. 3. There is a substantial opposition in Taiwan that want reunification (~20% of population supp…

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

I would not want to be maintaining a long-term naval blockade while constantly looking over my shoulder worrying about surprise attacks. Everyone knows where you are, and it would give plenty of time for a counter offensive to be planned. The US has something like 50 attack submarines, and a surprise attack from all of them at once would be a nightmare scenario for any fleet.

In the era of drones and missiles having your navy tied down in a blockade like that makes it all the more vulnerable.

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…

This video compares the Mediatek Dimensity to the Xring 03 (at the given timestamp 329s in) and finds significant differences in physical layout and performance: https://youtu.be/BCCJuOopLK8?t=329

Can't wait to see this in actual product and not a development board. It fulfill some of the original promise from ARM. And the world is about to turn upside down if most of that video show are proven to be true.

New CPU is 100% ARM design and nothing by Xiaomi other than "Chinese menu" configuration (i.e. how many blocks of this or that type,..). Apple CPU is a full custom design that just complies with ARM. Xiaomi Xring O3 CPU is designed by ARM and Xiaomi (as well as Mediatek) did not do any CPU design, other than custom bus interconnects, physical implementation on TSMC 3nm, an in-house NPU, and adopting next-generation L…

The custom integration is pretty big in and of itself. But the most important thing is that all these ARM C1 Ultra core is accessible to everybody. And it is performing well against Apple's CPU. The old Apple does better SoC advantage is vanished.

We will have A20 vs C2-Ultra this year. Can't wait to see it .

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.

If so they're going to be massively tariffed in the US. Chips are a national security sector.

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…

There was a noticeable degradation after the introduction of “liquid glass”. Of course I’m still on my 13 mini so I don’t think they really care about how changes impact the performance and battery life of my phone.
