Samsung does an Apple with its first Snapdragon X Elite laptop, suggesting the new Arm-based Windows machines aren't going to be a cheap alternative to x86 (www.pcgamer.com)

Interesting. Samsung making a bold move here, but one that could make sense.

I have been running Windows 10+11 on arm for years now, the next version of Windows Server 2025 already has an arm preview release. Windows ARM has for a long time had x86 emulation, and has supported x64 emulation since about the start of COVID.

Is it actually emulation? Macs don't do that.

They convert the x86 code into native ARM code, then execute it. Recompiling the software takes a moment, and some CPU instructions don't have a good equivalent, but for the most part it works very well.

MacOS does use the term translations for its Rosetta Layer while Windows Arm uses the term emulation. I do believe the technical difference is that MacOS converts x64 code to arm64 on the fly, while part of the reason for emulation on Windows is to support x86 and other architectures. Someone more knowledgeable than me may be able to better compare the two offerings.
