It's not as fast as Rosetta 2 on Apple Silicon (not by a long shot), but especially for lighter apps like productivity software, it isn't bad at all.
>Myth: Apple chips are the only ones to implement the x86 TSO memory model.
Nvidia Denver/Carmel and Fujitsu A64fx do too.
> And in an embarrassing turn of events, right now at least, you can eke out more performance running x86 code inside Apple's Rosetta 2 in a Linux VM under Windows than you can using Windows' native emulation layer!
So clearly there's more going on than just leveraging TSO support on Apple's chips.
>My frustration with this computer wasn’t a workload thing. It didn’t start out fast and gradually slow down as I opened more things and started more processes. It was peppered with glitches and freezes from start to finish.
I’d have only Slack open, and switching between channels would still take almost three seconds (yes, I timed it on my phone). Spotify, also with nothing in the background, would take 11 seconds to open, then be frozen for another four seconds before I could finally press play. When I typed in Chrome, I often saw significant lag, which led to all kinds of typos (because my words weren’t coming out until well after I’d written them). I’d try to watch YouTube videos, and the video would freeze while the audio continued. I’d use the Surface Pen to annotate a PDF, and my strokes would either be frustratingly late or not show up at all. I’d try to open Lightroom, and it would freeze multiple times and then crash.

The biggest reason for Windows' dominance for the better part of almost two decades was its insane backwards compatibility. Of course, this also created a myriad of problems for bloat and security, but it was pretty much one of their biggest selling points.
It's gotta be just as good as Apple's, or nobody's going to care, point-blank. They'll just buy a Mac and put Windows in a VM. You might even get better performance.
