What runs faster x64(intel) apps on Apple Silicon? Windows Arm or Parallels Emulator

As a developer, I am very interested.

Where do x64 apps run fastest on Apple Silicon?
- Windows 11 on Arm with x64 emulation layer
vs
- new Parallels x64 emulator VM with Windows 11 x64(intel)
Are there any benchmarks yet?

Hi ChristianK12,

We do not have available benchmarks however, you may note the below:

Windows 11 on ARM includes an x86 and x64 emulation layer that allows it to run traditional x64 applications. When you launch an x64 application inside a Windows ARM virtual machine, the operating system dynamically translates x64 instructions into ARM64 instructions at runtime, allowing many x64 applications to function without requiring modifications. However, performance can vary depending on how well the emulation translates the instructions and whether the application relies on low-level drivers or hardware-specific optimizations.

Most importantly, please note that since x64 applications run through emulation, they may perform slower than native ARM64 apps. Additionally, software that requires x64-specific drivers may not function properly
