> This smells somewhat legitimate and somewhat BS. The architecture itself looks impressive — TSMC 3nm, a 4+ GHz prime core, tons of cache, and a very wide execution engine. And the claimed Geekbench numbers, around 3,945 single-core and 15,221 multi-cor, are especially impressive, if not a little suspicious.

I was under the impression that there was still a trade export from TSMC to China [1]? Not to mention a near complete ban on ASML devices [2]? Maybe they exfiltrated a few chips into a lab, but can they really source production quantities?

> But it’s sorta like, let’s throw everything against the wall and get the biggest number we can. Do they show sustained performance over ten minutes? What’s the power draw when it’s doing 15K? What happens when you put it in an actual phone?

People using the same C1-Ultra core are struggling to get the same performance in applications where heat and power are important. It would be surprising if this is sustainable and not just a temporary boost.

Xiaomi also unveiled the Xring O100 AI chip and the Xring D100 smart-driving chip, the latter built to run models with up to 200 billion parameters locally, with commercial use planned for 2027. Reuters reports TSMC is producing the chips.

I guess we will find out very soon when Chinese customers get their devices. I don't know how they will even source enough LPDDR6 at reasonable prices.

i'm not kernel dev, but i've heard the folk at kernel always try to maintain a stable API so as not to break backward compatible, is this the case here ?

No, that stability is only promised for userland apps, not kernel-level stuff like drivers. In fact, there is no stable API/ABI for device drivers. Now this mostly isn't a big issue on the desktop/x86 world, because most drivers are open source, except for some exceptions like certain Broadcom drivers and old nVidia drivers. nVidia used to be a massive headache to deal with because the driver would frequently break w…

This basically answers my question about dark weather in the future for all of this. If Google is standing on an issue of trusting their clients to be in the right bucket of profitable customer to get through agreements and NDAs on what they’re proving unless you’re a multi national juicy enterprise target they’re really not the people I want to deal with. I don’t know what kind of deal Google has but I suspect they finance a substantial amount of “evolutions” for their purposes through the blob device vendors.

I'm sure it benchmarks well, but does it actually have good battery life?

Even aside from battery life, high TDP means thermal throttling under sustained load. Which most of these benchmarks don't really test, or if they did, the ambient temperature affects the results.

They do test continuous (1-hour) gaming performance in controlled environment regularly. Thermal throttling can be easily spotted on the frame rate vs time graph.

However a dev on fast hardware can still run profiles, and the fast hardware decreases the change/build/test cycle by more than enough to make it worthwhile. The only use of a slow machine is it gives a point where you can say more optimization isn't worth it. Everything else I can do better on a fast machine than a slow machine.

The fast machine lacks the most important element: the incentive to do optimizations in the first place.

It lacks one inventive. There are many incentives. Many developers love making things faster. Many developers get feedback from users which is itself incentive. Many projects track performance and that provides incentive. Many developers have a boss who cares about such things (this is the least likely of the above).

That summarizes my whole computer use. I used to believe it was my tolerance, but then I took out a good old YP-G70CB (Samsung Galaxy S WiFi 5.0) from a drawer and everything felt much snappier than my S25. The only computer that's the exception is my macbook m4. This thing was and still is ridiculously snappy.

It's a few different things. I've gone down a hardcore rabbit hole on this because I also find this exceptionally annoying. I now sometimes experience lag when typing into a terminal, where I am typing faster than characters appear, which is something that didn't even happen in the early 1990s on significantly less capable hardware. A very big portion of this is just Wirth's Law in motion. Software is getting worse r…

I think this post deserves a more in-depth discussion around the topic, I'd love to learn more.

"matches" could've also been written as "this year's product falls short of the competitor's last year one". And multithreaded is 10 cores vs 6 cores. I appreciate Apple being kept on their feet, but they're not dethroned yet.

Crazy how long Apple has been able to keep their lead, there is so much money trying to catch up

Back what up? That Russia invaded and destroyed Chechnya? Or Georgia?

What exactly do you want backed up? That countries across Eastern Europe saw how the russians operate and decided they don't want to be destroyed?

> You seem to forget the amount of killings Ukraine did there and why it started in the first place.

What killings did Ukraine make that resulted in russia invading Crimea? Or russia starting the invasion of the Donbass? MH17 maybe? Oh no, wait, that was the russians too.

> China that still seems acceptable China has made a tremendous effort to move to a clean(er) industrial system, using a lot of renewables and clean energy and improving environmental standards. At this point production in China is probably the best for the environment compared to most countries, including the US that is deeply invested in oil production.

United States: 384 gCO2/kWh China: 525 gCO2/kWh https://ourworldindata.org/electricity-mix

This comparison is meaningless because China is the worlds factory (including a major portion of what's consumed in the US ). So that CO2 number is their populations usage plus what's required to manufacture good for the most of the world. A huge part of US CO2 consumption has been outsourced to China.

> I'm willing to pay double the cost of a MacBook Pro for anything that can run Linux, similar performance to M5, have a decent battery, good touchpad, be silent, have a good display, be light and portable. This is Zenbook A16 right now, with recent patches posted to Linux ARM mailing list that support it in full.

>> good touchpad, be silent > This is Zenbook A16 right now, with recent patches posted to Linux ARM mailing list that support it in full. Including those two items I emphasised? This is usually where Apple's competition fail, mostly because they don't even consider it.

I specifically check the touchpad as well, since right now I am on a MacBook running Asahi and I just can't stand other touchpads. I even tried a Thinkpad for a while and had to return it.

However, while ZenBook's touchpad is not haptic, it's at least a glass one and generally praised for being quite good in comparison. I asked a bunch of people. Notably I prefer to double tap than press on my touchpads, so I don't really care about the haptic feedback, but to each their own. Still, I think it's worth trying it. BestBuy should have them in store if you're in US, I haven't tried it myself yet.

And yes, it's surprisingly quiet. It's a bigger form factor (16") despite very low weight, so that helps with heat dissipation and X2 is very efficient.

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…

Features expand to fill all available hardware. Both the OS and apps got more features, got more flashy, got more complicated. If you were able to run those old original apps, they would likely be VERY fast on your newer device.
