2024 could be the year the PC finally dumps x86 for Arm, all thanks to Windows 12 and Qualcomm’s new chip::We’ve already reported on Qualcomm’s new 12-core Arm uberchip, the Snapdragon X Elite, and its claims of x86-beating performance and efficiency. But it takes two to tango when it comes a maj
There’s already a compatibility layer. Microsoft had one before Rosetta 2 was available. You can test it yourself with many windows on arm dev builds that exists, or with a Mac running windows in a VM.
Verdict; not as good as Apple (not sure how it compares with the one from Linux) but good enough. https://beebomal.pages.dev/posts/apple-s-rosetta-2-vs-windows-x86-emulation-explained/
Ah right! I forgot about Windows on ARM.
If you had read the article, they covered all this. Including your original comment and the reply to it.
Ain’t nobody got time for that.
But you do have time to complain
Was my comment really a complaint? I guess anything can be anything if you believe hard enough!
It isn’t as good because Rosetta 2 exploits some custom features built into the their M processors. Specifically, there is a special mode that strengthens the memory model, which is critical for both performance and correctness when it comes to executing multithreaded x86 programs on ARM.
