Second this. Not to mention INSTANT resume from hibernation! It’s fucking crazy. I can use this thing ALL DAY doing webGL CAD work and Orca Slicer and barely scratch 50%.
With a modern system, I honestly don’t think there’s a noticeable difference between suspend to ram and suspend to disk. They’ve gotten the boot times down so much that it’s lightning-fast. My work laptop’s default is suspend to disk, and I don’t notice a difference except when it prompts for the bitlocker password.
S0 standby is borderline unusable on many PCs. On Apple silicon macs it’s damn near flawless.
My current laptop is probably the last machine to support S3 standby and I do not look forward to replacing it and being forced back into a laptop that overheats and crashes in my backpack in less than 15 minutes. On my basic T14 it works ok for the most part, but my full fat Thinkpad P1 with an i9 is in S0 standby for longer than a few minutes, and sometimes uses more power than when it was fully on. Maybe Meteor lake with it’s LP E cores will fix this but I doubt it.
It’s just that traditionally Intel and AMD earn most of their money from the server and enterprise sectors where high performance is more important than super low power usage. And even with that, AMD’s Z1 Extreme also gets within striking distance of the M3 at a similar power draw. It also helps that Apple is generally one node ahead.
If there’s ‘nothing stopping’ it then why has nobody done it? Apple moved from x86 to ARM. Mobile is all ARM. All the big cloud providers are doing their own ARM chips. Intel killed off much of the architectural competition with Itanic in the early 2000’s. Why stop?
Their primary money makers are what’s stopping them I reckon. Apple’s move to ARM is because they already had a ton of experience with building their own in house processors for their mobile devices and ARM licenses stock chip designs, making it easier for other companies to come up with their own custom chips whereas there really isn’t any equivalent for x86-64. There were some disagreements between Intel and AMD over patents on the x86 instruction set too.
This article fails to mention the single biggest differentiator between x86 and ARM: their memory models. Considering the sheer amount of everyday software that is going multithreaded, this is a huge issue, and the reason why ARM drastically outperforms x86 running software like modern web browsers.
On the x86 architecture, RAM is used by the CPU and the GPU has a huge penalty when accessing main RAM. It therefore has onboard graphics memory.
On ARM this is unified so GPU and CPU can both access the same memory, at the same penalty. This means a huge class of embarrassingly parallel problems can be solved quicker on this architecture.
As an ARM Mac user, I wouldn’t trade all this new battery life for an x86 processor

tbh it has been nearly flawless on win11 for me with an amd cpu
(just make sure to disable automatic windows/defender updates unless you want to get woken up by jet turbine sounds in the middle of the night)
There’s nothing stopping x86-64 processors from being power efficient. This article is pretty technical but does a really good explanation of why that’s the case: https://chipsandcheese.com/2024/03/27/why-x86-doesnt-need-to-die/

So there is something stopping them. The manufacturers.

Do you mind elaborating what is it about the difference on their memory models that makes a difference?
On the x86 architecture, RAM is used by the CPU and the GPU has a huge penalty when accessing main RAM. It therefore has onboard graphics memory.
On ARM this is unified so GPU and CPU can both access the same memory, at the same penalty. This means a huge class of embarrassingly parallel problems can be solved quicker on this architecture.

Idk, the battery of my 12.9“ iPad Pro is great.
