How fast is Microsoft’s new PRISM x86-64 Emulator

Microsoft has introduced a new x86-64 emulator called PRISM with the latest Windows 11 update, aimed at improving the performance of Intel and AMD code on ARM-based Windows laptops. Designed to boost the performance of Intel and AMD applications on ARM-based Windows laptops, this update is crucial for users who need to run x86-64 applications on ARM devices.

The PRISM emulator aims to bridge the gap between the traditional x86-64 architecture and the increasingly popular ARM processors, allowing a seamless computing experience across different platforms. Gary Explains has carried out some excellent performance tests to provide  more insight into just how fast the new Microsoft PRISM x86-64 Emulator is on Windows 11.  Check out the video below to learn more.

PRISM x86-64 Emulator?

The need for emulation arises from the fact that Windows has traditionally operated on x86 and x86-64 architectures. However, with the rise of ARM processors in mobile devices and laptops, there is a growing demand for running legacy applications built for Intel and AMD architectures on these new platforms. PRISM addresses this challenge by translating x86-64 instructions into ARM-compatible code, allowing older software to run smoothly on newer hardware.

One of the most notable aspects of the PRISM emulator is the substantial performance improvements it offers over previous solutions. Tests conducted on the Snapdragon X Elite processor reveal that emulated applications run more than twice as fast compared to earlier ARM devices. This performance leap is a catalyst for users who rely on demanding x86-64 applications, making ARM-based systems a viable option for professional use.

To gauge the real-world impact of the PRISM emulator, performance tests were carried out on a Surface Pro X running Windows 11 24H2. The results are promising:

• Speedometer 3 (Firefox): 10% faster performance
• Cinebench R23: 8% increase in single-core performance and a 42% boost in multi-core performance
• Handbrake: 8% overall performance improvement

These benchmarks not only highlight the speed enhancements brought about by PRISM but also demonstrate its ability to improve the efficiency of multi-threaded applications. This development opens up new possibilities for ARM-based devices in various professional fields.

The Growing Ecosystem of ARM-Native Applications

While the PRISM emulator plays a crucial role in running x86-64 applications on ARM devices, it is important to note that the ecosystem of ARM-native applications is also expanding rapidly. Major software vendors, such as Microsoft, Google, and Adobe, now offer ARM-native versions of their popular applications, including Microsoft Office, Google Chrome, and Adobe Photoshop. This growing support ensures optimized performance without relying solely on emulation, further enhancing the user experience on ARM-based devices.

The combination of the PRISM emulator and the latest Snapdragon processors significantly improves the overall user experience on ARM-based Windows devices. Users can now run a wider range of applications with better performance and stability, making these devices more versatile and efficient. This development encourages users to consider the benefits of a dual architecture ecosystem, where both ARM and x86-64 applications coexist seamlessly.

The introduction of the PRISM emulator, along with advancements in ARM processors like the Snapdragon X Elite, marks a significant step forward in the performance of x86-64 applications on ARM-based Windows devices. This progress not only enhances the usability of ARM-based laptops but also paves the way for a more versatile and efficient computing environment. As the technology continues to evolve, users can expect even greater performance gains and a smoother transition between different architectures, ultimately leading to a more seamless and productive computing experience.
