I've got a 6th gen X1 carbon and under windows the thing has the fan on high all the time. Switched to Linux (mint) and I went a couple months before I heard the fan, doing all the same things. I don't know what windows is doing these days but it isn't doing it for me, the end user.

T460s user here, on Windows (and Hackintosh, for the sake of bad comparison), my system idled ~40-45c and the fans also ran constantly. Put Linux on it, add auto-cpufreq, and then it idles ~27c (30c with external display). No fans unless I launch games, have heavy network usage for >5 minutes, or compile something. I'd probably give the Macbooks (or this new Thinkpad) a closer look if I didn't work with Docker consta…

On Windows, did you use the Lenovo provided software to manage cooling? If you did a fresh install of Windows and didn't install the OEM fan and CPU tooling, but then did install CPU tooling on Linux, its not quite a fair comparison.

I've got a 460s and it will run pretty warm if you let it. If you tell it to not run so hot it'll keep the CPU throttled down a bit more aggressively and keep it cooler. That generation of Intel CPU was always a bit on the warm side when it wanted to actually do anything. Especially anything related to video encoding/decoding, using stuff like Zoom or Meet or Teams really makes the machine get warm.

> Biggest lie ever. People want 16:10, but for years the industry shove 16:9 to your customer because it was the cheaper panel. Any background on this? I always assumed 16:9 became popular because of videos.

If you are authoring 16:9 content, something like 16:10 allows for some UI controls to be displayed along with 16:9 video at native resolution during previews. When programming, more space is better. So for creators, 16:10 is unambiguously better.

I get why 16:10 is preferable (I'd like 4:3 even more, or even 1:1 on a desktop), what I don't understand is the incentive to push 16:9. Is it just because less pixels -> fewer expenses.

See Snapdragon 7c Chromebook hardware. There's quite some of those available. The Galaxy Book Go using the same SoC uses Windows on Arm64 instead.

Quite a lot of those Windows on arm64 SoCs also ship on Chromebooks, ensuring Linux support at some point.

That's, like, your opinion, man.

Give me a high end mobile workstation with 4:3!

Why not 1:1?

how many raw NT kernel APIs do your typical Win32 programs call? probably zero? so I guess Win32 programs aren't really Windows programs then? Win32 running on top of NT is no different to the Android API running on top of the Linux kernel

Whatever makes you feel happy, beware not to stumble on the fuchsia carpet on the way out.

You can generally buy a ThinkPad at 2/3 or even 1/2 of the list price.

what a fantastic rebuttal

watch out for the Wine stain

These windows on arm devices are UEFI/ACPI, not uboot/DT. They should work, if someone puts the effort into porting all the drivers, and working around all the quirks they are sure to have. Why QC doesn't do this, and get them SystemReady certified is a mystery.

Snapdragon 8cx Gen 3 is 4xX1 + 4xA78, with no A55s.

I eat my statement. That looks like a better configuration than an octa-A78C, but only if the licensing cost is the same or you REALLY have a need for the latest extensions.

So, it actually is X1C and A78C.

https://blogs.windows.com/windowsexperience/2022/02/28/mwc-2... references PAC support, which is only in the C variant of those cores.
