Understanding Microsoft’s Prism: A Closer Look at the Emulation Engine for Windows on Arm and Its Comparison to Apple’s Rosetta 2

This week, there have been numerous speculations about new developments in the realm of Windows laptops and portable devices. Microsoft’s Surface and Windows 11 AI Show generated a buzz with its range of announcements, including the launch of the Copilot+ AI PC range powered by Qualcomm Snapdragon X Elite and X more ARM processors. The appeal of Windows on Arm is set to increase as Microsoft introduced the ARM64EC Application Binary Interface (ABI) for developers to enhance performance on ARM-powered Windows devices.

The introduction of the new emulator called Prism for ARM devices has created excitement, particularly with the upcoming Microsoft Surface Pro 11 and Surface Laptop 7. Prism acts as an emulator for ARM-powered Windows devices, translating software code into traditional x86-64 binaries to ensure compatibility. Microsoft claims that emulated apps on Snapdragon X Elite devices offer more than double the speed compared to previous-generation Windows Arm devices running Windows 11 22H2.

Behind these advancements in Windows on Arm are former Apple employees who now work with Qualcomm on the Snapdragon platform. Qualcomm acquired Nuvia, a startup founded by these individuals with experience in designing Apple’s A Series SoC, leading to improvements in emulating x86-64 binaries on ARM processors. Prism’s performance boost aligns with Microsoft’s focus on enhancing the user experience on ARM-based Windows devices.

While native ARM apps are on the rise, users can still benefit from Prism emulation on their existing ARM-powered Windows devices. The performance improvements brought by Prism mean that both native and emulated apps run smoothly. Microsoft’s emphasis on native apps and the efficiency of Prism suggest a promising future for users of ARM-based Windows PCs.

The prospect of utilizing Prism on older ARM-based Windows PCs, coupled with the performance gains demonstrated on new Copilot+ AI PCs, makes the transition to ARM devices more appealing. The comparison between the Surface Pro 11 and older ARM-based devices highlights the potential savings and improved performance offered by Prism emulation. Overall, the advancements in Windows on Arm, driven by Prism and the Snapdragon platform, present an exciting opportunity for users looking to optimize their computing experience.
