Quick guide
With the Windows 11 update, Microsoft has introduced Prism, a new x86-64 emulator designed to improve the performance of Windows laptops based on Arm architecture. This is especially important for users with older hardware, promising to improve the emulation of Intel and AMD code on these devices. Emulation is critical in Arm-based Windows devices, as many legacy applications are still exclusive to the x86-64 architecture. Prism is designed to boost app performance, and Microsoft claims that Copilot Plus PCs powered by Snapdragon X Elite processors are more than twice as powerful. Despite progress in Arm-native applications, emulation support is still needed for software such as gaming. The introduction of this emulator demonstrates the continued evolution of the Windows ecosystem to the Arm architecture.
Boost performance with Windows 11 updates
With the upcoming Windows 11 update, Microsoft has introduced Prism, a new x86-64 emulator designed to improve the performance of Windows laptops based on Arm architecture. This update is especially important for users with older hardware, as it promises to improve the emulation of Intel and AMD code on these devices. The introduction of Prism coincides with the arrival of the Snapdragon X-based Copilot Plus PC on the market, raising curiosity about the impact of this new emulator on overall system performance.
The importance of emulation on Arm-based Windows devices
Due to Windows' historical association with x86 and x86-64 architectures, emulation remains a key aspect of Arm-based Windows devices. While new applications can be compiled to run natively on x86-64 and Arm processors, many older applications remain exclusive to x86-64. The shift to a dual-architecture Windows ecosystem that supports x86-64 and Arm-64 (Arch64) was achieved thanks to processors such as Qualcomm's Snapdragon X-series. It is not feasible to run x86/x64 code directly on Arm processors without emulation because of differences in instruction sets.
Simulate the impact on application performance
The redesigned Arm simulation, known as Prism in Windows 11 24H2, aims to address the performance penalties imposed by previous simulation methods. Microsoft claims that the performance of the new Copilot Plus PCs powered by the Snapdragon X Elite processor is more than two times better than that of earlier Windows Arm devices. This improvement is not only due to the software enhancements, but also to the features of the Snapdragon X Elite platform. Despite the progress made in the field of Arm-native applications, the need for simulation still exists for a wide range of software, including games.
