Isn't it a searing indictment of the entire Intel laptop chip lineup that a MacBook Air M1 has half the battery capacity (50Wh) while giving easily twice the battery life with as good or better performance -- and with no fans!

It seems that we're not getting anything close to the M1. I'll stick to second-hand thinkpads for now, but I'd really like to have a thinkpad with some ARM resembling M1. We had a good shot with frame.work but it seems nobody is going to make other boards nor are keyboards really replaceable with thinkpad-like keyboards, so the swappable parts concept falls very short for now.

I agree that X13s looks underpowered comparing to Apple's laptops, but from my understanding of reviews - it's working machine, not a proof of concept of WoA style gimmick

Why does it have to look like a Macbook?

Bring back the G3 color clamshells!

It's also a searing indictment of Linux. I get less than half the battery life on my Alienware AMD laptop under Linux than under Windows. I don't know what Linux is doing wrong here, but it is not energy efficient.

Don't blame Linux developers for the behavior of OEMs and your choice of hardware.

Why in the world if you care about battery life do you put a 12th gen Intel H-series CPU in your laptop, and not a 5th or 6th gen AMD CPU? My Lenovo gaming laptop gets 5-6 hours with a 4th gen AMD H-series on a 60Wh battery.

Can you elaborate why these architectures give better battery life?

I can tell you that I can run Linux at ~3.5 Watts/hour ("normal" workflow - chiefly on documents) on my laptop: you should check what is draining your battery, because the issue on efficiency you see is not necessary at all.

It's always the same story. Intel makes the chip, other people makes the software that runs on it. Apple makes both. On the better permormance, I have yet to see. This laptop drives 4 external displays, M1 or M2 can do the same?

Earlier quoted context omitted.

Alienware? I suspect you have a dedicated graphics card? Or any other "performance"-component for that matter, which typically requires proprietary software counterpart (drivers) to run efficiently . Most vendors only ship decent Windows drivers, and the Linux counterpart (if any) is considered "good enough". I would not consider this the fault of kernel developers. Often there is basically nothing they can do. You j…

Probably an Optimus setup on the Windows side. It basically powers down the graphics card most of the time and switches to the lighter Intel graphics instead. Linux support for Optimus is poor and usually you end up having to choose either good battery life or good gaming performance.

This is likely it as the AMD CPU has a built-in low power Radeon GPU, and there's a monster Nvidia card for gaming.

Do you know how I can check if the discrete card is being used / drawing power?

I don't think I know enough to give a great answer.

The obvious is TSMC's "7nm" and iterative 6nm enables greater efficiency over "Intel 7." Beyond that, presumably there's some IPC advantage that means more work can be done with the same clocks and power draw.

It's odd, because 12th gen is quite performant and seems efficient, and yet somehow the battery life isn't very good.

Do 10 hours of battery life "while surfing the web with Wi-Fi" really strike anyone as a strong argument these days? I'm a bit uncertain. I got 9 hours of the same out of my 2017 MacBook Air's measly battery when it was new 5 years ago . I know for a fact I don't need 14 CPU cores to get my browsing habits satisified. This laptop is trying to be a "premium business workstation" by packing a CPU that's crazy powerful…

FWIW, 10 hours of battery life with a discrete GPU enabled is fairly unprecedented. Even the 16" Macbooks that shipped with discrete GPUs would struggle to sustain the CPU and GPU for 5 hours of parallel use.

Did those not have automatic graphics switching? I tapped out of Intel MBPs around 2017, but AGS made using them pretty decent for the time.
