Whoever can make a compatibility layer that successfully translates x86/64 to arm and vice versa and make it widely available will be a major player in the market. Valve has already somewhat done something similar with proton and Apple with Rosetta 2.

Apple developed it as a stopgap. In the Windows world x86/64 will be around for a long long time. Not sure if anyone is willing to support something like that for the next 10 years.
It's all a question of market share. If (big if) arm gets a foothold into the Windows market, software vendors will simply offer two binaries and/or Microsoft could offer tooling to offer easy porting.
Apple's real genius move though is not Rosetta, but including x86 compatibility features into the Mx chips. That way the emulation is much faster.
Windows does have a 32/64 bit x86 compatibility layer and most of what I've seen through limited bashing around in VS2022 leads me to believe that it has arm as a fairly targetable build target already.
Proton and Rosetta 2 are two totally different beasts. One allows windows programs to run on non-windows hosts and one translates x86 to Arm.
I’m not aware of Proton doing anything like Rosetta 2 and if it did Steam would have probably used an Arm chip in their Steam Deck instead of an x86.
Maintaining 2-way compatibility doesn’t seem like an important goal. One way, x86->Arm, sure but not Arm->x86. Apple clearly sees x86 as a dead end for its own product lines and we will see if the rest of the industry follows suit over time. Of course there is a ton tied up in x86 but aside from legacy apps or games I don’t have much need of x86 in my life.
Even the servers I run are trending towards Arm due to the power savings. AWS graviton stuff is like ~25-30% cheaper than x86 last I looked
I understand proton isn't the same thing, it was just an example of a compatibility layer...and how would a bidirectional compatibility layer not be beneficial? X86 in servers may be going away and even that's debatable, but x86 isn't going anywhere in the consumer space. Graviton chips are great, but they're useless if there's no viable way to translate those x86 legacy applications over to ARM without breaking the bank until your business is ready to transition the workload to ARM.
Amazon was working on a compatibility layer specifically for this purpose, however I suspect they've given up because they've slowly added Intel and AMD chipsets back into their general purpose ec2 class for newer generations and there hasn't been a single word about compatibility with graviton other than just use arm based workloads.
You just can't move to ARM because it's cheaper, that's just not going to work. You need to make the effort to move away from x86 and adopt applications that are arm native before making that jump. With a compatibility layer it doesn't matter, that's where the money is, if I can build a compatibility layer that translates an x86 binary to an arm binary, then I can move those workloads to the cheaper and more efficient server class.

FEX-Emu is basically that. They're still in an early state but they showed Sonic Mania running perfectly a few days ago.

Windows on ARM is a thing, it will run x86 binaries.
Gord forbid those binaries want to do any actual work though...
I don’t follow?
Windows on ARM will run x86 binaries. But if these binaries require any real processing power, they choke or run really really slowly.
I guess it depends on how you define “real processing power”. I run Windows on Arm on my Mac Studio through Parallels. I installed Steam and played Civ 4 and it’s great. Sure, it’s an old game but it runs smoothly.
It's gotta be Microsoft building it into Windows. The Apple Silicon transition wouldn't have been nearly as smooth if people had to pay for, say, CrossOver or something to use their Intel apps. And the tepid response to the ARM Surface models makes me think that it's a must, despite the UWP dream.
The good news is that Rosetta 2 shows it can be done extremely well!
Someone should revive transmeta and gear it towards arm.
Isn't that just box64/box86
The recent Snapdragon chips have been awesome, but that's not Apple's magic, it's their x86 to ARM translation layer
And the fact that they have silicon space dedicated to accelerating that translation layer specifically.
Good software and good hardware married to make a kickass move to ARM.
It's not just the translation layer. There's hardware built into the CPU to accelerate the translation.
Pair that with the CPUs already being so incredibly efficient and you've got something that runs x86 programs as good as the old hardware.
I look forward to being able to buy/build an ARM-based Linux box with MacBook Pro-class performance.
Why do you want to use ARM in a desktop?
The main benefits of it are power-saving.
ARM can be really powerful, there are ARM servers out there.
More powerful than X86? Or are there other reasons to use it in a desktop?

It would be an instant buy for me, especially since it wouldn't be as locked down and work better with Linux. I'll deal with the software issues later, gimmie now!
Good luck making that work with Windows. If it does its not going to be profitable as Microsoft will eat your arm.
I would love to see one of these running Linux but I don't see that happening realistically
Already does?
Windows on ARM is a thing, and it does x64 and x86 translation.
The chips likely also have hardware to accelerate translation as well, to compete with M1 and M2 chips.
Where's the installation iso?
Here's an archive of all Windows updates and builds. This query is for arm64.
That's not a safe place to get isos
From a security perspective, as long as you check the hash against Microsoft's website then it should be okay. Otherwise I'm not sure where to get Windows on ARM ISO's from.
That's my point. Microsoft doesn't seem to want you to outside of the surface
I mean yeah you're not wrong. If only the Surface wasn't so absurdly overpriced for what you get.
I sure hope it will come with SystemReady or a similar standard for something UEFI-like instead of the custom per board image many ARM devices need currently.
This is the best summary I could come up with:
Qualcomm's annual "Snapdragon Summit" is coming up later this month, and the company appears ready to share more about its long-planned next-generation Arm processor for PCs.
The company hasn't shared many specifics yet, but yesterday we finally got a name: "Snapdragon X," which is coming in 2024, and it may finally do for Arm-powered Windows PCs what Apple Silicon chips did for Macs a few years ago (though it's coming a bit later than Qualcomm had initially hoped).
But those chips have never quite been fast enough to challenge Intel's Core or AMD's Ryzen CPUs in mainstream laptops.
Any performance deficit is especially noticeable because many people will run at least a few apps designed for the x86 version of Windows, code that needs to be translated on the fly for Arm processors.
Even if Qualcomm delivers an Arm chip that's significantly faster and more power-efficient than its current offerings, there are still software hurdles to overcome.
In other words, they were negotiated based on Nuvia's then-stated focus on server CPUs, rather than high-volume processors for consumer PCs.
