ARM has THREE instruction sets. (four?) aarch32, aarch64, and various incarnations of Thumb. (A PI 5 supports all three).
Okay? x86-64 has like twenty extensions. What's your point?
(M1 does, because they don't implement aarch32, or thumb).
On the Mac, you can fix neither the hardware nor the software; it's like a car with the hood welded shut.
On the Framework, you can fix (or change) both, and there is no built-in expiry date beyond which you cannot update the software.
Is performance really the only thing that matters?

I had not realized that Apple did not implement any of the 32-bit ARM environment, but that cuts the legs out of this argument in the article: "In Anandtech’s interview, Jim Keller noted that both x86 and ARM both added features over time as software demands evolved. Both got cleaned up a bit when they went 64-bit, but remain old instruction sets that have seen years of iteration." I still say that x86 must run two F…
> I still say that x86 must run two FPUs all the time, and that has to cost some power (AMD must run three - it also has 3dNow). Legacy floating-point and SIMD instructions exposed by the ISA (and extensions to it) don't have any bearing on how the hardware works internally. Additionally, AMD processors haven't supported 3DNow! in over a decade -- K10 was the last processor family to support it.
Right. Not.

When you say efficiency, I assume you’re factoring in performance of the device as well? Maybe run Geekbench 6 and see.
I am not the original commenter; but they said "low-power user cases" i.e. very much not when running Geekbench; rather when it is near idle.

When limited to 5 watts, the Ryzen HX 370 works pretty darn well. In some low-power user cases, my GPD Pocket 4 is more power efficient than my M3 MBA.
We will need some citations on that as the GPD Pocket 4 isn't even the most power efficient pocket pc. Closest I've seen is an uncited Reddit thread talking about usb c charging draw when running a task, conflating it with power usage.

> One of their best acquisitions ever in my opinion… NeXT? But yes, I completely get what you’re saying, I just couldn’t resist. It was an amazingly long sighted strategic move, for sure.
I almost feel like NeXT was a reverse acquisition, like Apple became NeXT with an Apple logo.
Craig Federighi is a notable NeXT alum. And... I think he might be the only one left in leadership.
NeXT was a comparatively small company compared to Apple.
Take a look at the mobile arena: For an average everyday-Joe, he'd be hard-pressed to notice that much of an actual difference between Apple iOS and Android. They're both highly refined mobile OSs that offer remarkably similar core experiences: instant on, home screens with Apps that run sandboxes and are only installable via an App Store, extremely efficient hardware inside that offer amazing performance and efficiency in battery life when compared to a notebook.
It's that Apple took one step further and decided to make a Smartphone INTO a Laptop with their M-series MacBooks. It was easy to do with the iPadOS, as it's really just a giant phone, but it was impressive they were also able to do that with MacOS as well, leading me to believe it should be possible with Windows too.
Qualcomm and its X-Elite chips is a step in a better direction Microsoft needs to offer a competitive experience to the MacBook, but I'm not sure it's enough, not without a complete re-write of their OS, to overcome all its WinTel baggage.
I think a completely new PC Laptop OS is needed, one that runs as efficiently as MacOS does with modern ARM hardware (Qualcomm, MediaTek, Samsung Exynos). Maybe Google via some sort of full Desktop Android OS (not Chromebook) or perhaps Microsoft with a completely built-from-scratch Linux-derived Windows? Or, indeed, maybe SteamOS?
Regardless, if the last five years has shown us anything, the divide between Apple's MacOS/iPadOS+M-seriesChips and the old WinTel world has just widened and everyone thinks it will continue that trend. How long will the general public stay with a clearly inferior PC product? History has suggested not long (iPhone vs BlackBerry for example!)...

These figures are very plausible. Most Linux distros are terribly inefficient by default. Linux can actually meet or even exceed Window's power efficiently, at least at some tasks, but it takes a lot of work to get there. I'd start with powertop and TLP. As usual, the Arch wiki is a good place to find more information: https://wiki.archlinux.org/title/Power_management
Those numbers would imply 50W consumption at idle (for typical battery capacities). That's insane. I've used Linux laptops since ~2007, and am well aware of the issues. 12x is well beyond normal.
That's the case.
