Compare native ARM64 apps with emulated x86 x64 apps Windows 11 It's no longer a laboratory curiosity. With the arrival of new chips and system improvements, understanding what to choose based on your use case can save you time, battery life, and headaches.
If you wonder When it is better to go native and when to accept emulationHere you'll find a clear guide, with compatibility data, performance, developer tools, ecosystem status, and real-world scenarios that will help you decide without getting bogged down in unnecessary technicalities.
What Windows 11 means for ARM and why it matters in this comparison
Windows 11 for ARM is the edition of Windows designed for 64-bit ARM processors, different from the usual x86 x64 Intel and AMD. ARM chips prioritize efficiency and low power consumption, which translates into thinner, cooler devices with a long battery life, although without as much sustained power under heavy loads like certain desktop CPUs.
For years ARM was something secondary, but the pull of mobile phones, Raspberry Pi or Arduino, and the thrust of portable lightweight, have changed the landscape. Microsoft, not to give ground to Linux and to compete head-to-head with Apple and its Apple Silicon family, has pushed its Windows on ARM platform to make the experience as similar as possible to that of a traditional PC, with one eye on autonomy and the other on compatibility.
Native ARM64 vs. x86 x64 Emulation on Windows 11
When you run a native ARM64 app, The code is compiled specifically for the ARM64 architectureThis means better performance per watt, lower latency, and lower battery consumption compared to running the same app translated or emulated.
Emulated x86 x64 apps work on Windows 11 for ARM without the user having to do anything special. Translation allows moving legacy software without recompiling, but the performance and efficiency penalty exists, and is most noticeable in intensive or graphics-intensive tasks.
State of the ecosystem and compatibility in 2025
By early 2025, the native ARM64 catalog has grown significantly: Microsoft 365 in full With Teams, PowerPoint, Outlook, Word, Excel, OneDrive and OneNote already fly on ARM; there are also native versions of Chrome, Slack, Spotify, Zoom, WhatsApp, Blender, Affinity Suite and DaVinci Resolve, Among others.
For apps that do not yet have a native build, Microsoft has introduced Prism, its next-generation emulation engine, available on Copilot+ devices with Snapdragon X processors and expanding to more Windows 11 devices. The leap from previous generations It is especially noticeable in general fluency and compatibility.

Performance and autonomy on ARM devices
One of the most powerful reasons to choose native apps is that ARM's efficiency shines when software is optimized. Devices with the Qualcomm Snapdragon X Elite easily exceed 20 hours of battery life in typical use, with contained temperatures and slim or even fanless designs.
In productivity, the results of chips like Snapdragon X Elite or Microsoft SQ3 They're on par with 12th and even 13th generation Intel CPUs for office tasks, browsing, and communication. If your day revolves around documents, video calls, and the web, Native ARM64 will give you the best experience and the battery will last longer.
Games and multimedia: where emulation is most important
In gaming, the outlook is mixed. Steam now officially supports Windows on ARM, but many games still rely on x86-64 binaries and complex anti-piracy. Emulation can penalize FPS and load times here, especially in titles with engines highly optimized for x86.
That said, with Windows 64's ARM11EC, many developers are migrating their apps step by step, combining native ARM64 parts and x64 modules. This hybrid approach improves compatibility without slowing down the transition and we're likely to see more games and launchers adapting to this strategy.
Recommended use cases for native ARM64 apps
Anything involving productivity, web, light multimedia, or moderate content creation benefits from native ARM64 apps. Office, browsers like Chrome, Edge or Firefox, work clients like Citrix, Zoom, and Slack, and editors like Photoshop and Lightroom already have ARM-optimized builds.
If your key tool has an ARM64 version, the choice is clear: install it in its native buildYou'll gain speed, responsiveness, and battery life, and your device will run cooler, something you'll appreciate during long video calls or sessions outside the office.
When to accept x86 x64 emulation
If you depend on legacy or specialized software that is not yet on ARM, emulation is the necessary bridge. Prism has greatly improved the experience, and for non-critical tasks the difference can be manageable. Still, under heavy loads, the penalty is noticeable.
In Windows 11 for ARM, emulation covers both 86-bit x32 and 64-bit x64. In Windows 10 IoT on ARM, only x86 was emulated, so the jump in Windows 11 opens the door to more compatibility in professional environments.
Devices and target audience
Windows 11 for ARM is designed for 64-bit ARM CPU and has been seen in devices such as the Surface Pro X, Samsung Galaxy Book Go, Acer Spin 7, and HP Elite Folio. These are laptops and convertibles that aim to enormous autonomy, minimal thickness and contained temperatures, in exchange for not seeking the raw power of x86 stations.
The user experience is practically identical to that of a conventional Windows 11 If you use adapted apps. For very demanding tasks, you may notice the ceiling sooner, but the advantage for mobile users, students, and remote workers is undeniable.
Comparison with Apple Silicon
Since 2020, the Mac with Apple Silicon they set the pace, and in 2025 the M3 Pro and M3 Max chips They dominate loads such as video, 3D, or large multi-threaded builds. Still, Windows on ARM closes the gap and in office tasks and navigation there is no longer any discussion.
In collaboration with Microsoft Qualcomm, MediaTek and Samsung, ARM is being pushed into the mainstream Windows market. There is more fragmentation than in Apple's closed ecosystem, but computers with Snapdragon X Elite perform close to the M2 in general use, falling behind M3 in multi-threaded creatives.
Developer support and migration path
The big question for any ISV is whether compiling an ARM64 version is worth it. With Visual Studio 2022 on ARM and ARM64EC, the pace is becoming more and more comfortable, and the program App Assure helps companies migrate without trauma.
Projects like Project Volterra and ARM Developer Kit have given devs native testing machines. In addition, frameworks like Flutter, Electron or .NET MAUI facilitate cross-platform builds and Debug Progressive Web Apps, shortening times and reducing friction when offering ARM64 binaries.
IoT Enterprise on ARM vs x86 x64
Windows IoT Enterprise on ARM offers the same features than its x64 edition in functionality, but with nuances in apps and drivers. On ARM you can run native ARM64 apps and also emulated x86 x64 apps depending on the system version.
The golden rule in IoT is clear: compiles drivers natively for ARM64Many arrive on Windows or via BSP and others through Windows UpdateIf it doesn't exist, you have to ask the supplier or develop it internally.
About hardware, Windows IoT Enterprise on ARM supports SoC from NXP and QualcommNXP is ideal if you are looking for low power and cost for thin clients, kiosks or HMI, while Qualcomm provides more muscle for advanced visualization or AI loading.

Prism, ARM64EC, and the role of well-understood emulation
Prism is the new emulation engine that comes with the Copilot plus Snapdragon X-based PCs and extends to other Windows 11 machines. The promise is to raise the bar in performance and compatibility of emulated apps compared to previous generations.
ARM64EC allows developers mix ARM64 and x64 modulesIt's a very practical way to migrate large applications piecemeal without breaking compatibility with plugins, extensions, or SDKs that don't yet have a native build.
Operating costs and lessons from the server world
While our focus is on Windows 11 client and IoT, server metrics help understand Why ARM64 is so attractiveIn tests comparing equivalent cloud instances, key figures were observed in favor of ARM64.
According to those numbers, ARM64 servers processed 54 percent more applications than the x64 equivalents. Efficiency per second was also better, with 32 requests per second versus 21,67 on x64, and a P95 of 383 ms versus 893 ms, showing lower latency under load.
Translated to laptop, it is not a direct equivalent, but it explains why native ARM64 apps in Windows 11 they usually feel more agile at the same load and why the battery lasts longer with optimized software.
Industry, availability and near future
Manufacturers such as HP, Dell or ASUS are going adding new ARM models in their 2025 roadmaps. The success of these releases will be key to consolidating the market and pushing more developers to publish ARM64 builds the first day.
Everything points to ARM taking a crucial role in the PC, with Windows preparing deeper integrations for this architecture. Flagship laptops relying exclusively on ARM are expected in the business and ultraportable segments.
Practical recommendations for choosing native or emulated
If your work suite is already in native ARM64, prioritize those versionsYou'll gain performance and hours of battery life. For critical tools not yet available on ARM, emulates with Prism and check worksonwoa for any known issues.
For developers, the sensible plan is hybrid with ARM64EC, starting with modules with the greatest impact on performance. Don't forget native drivers in IoT solutions and validate third-party dependencies as soon as possible to avoid late blocks.
Historically, Windows for ARM was more tied to manufacturers, but the current push indicates a clear focus on the general market, with more teams, more software, and mature tools for compiling and debugging on ARM.
To close the circle, if your profile is mobile and prioritizes battery and silence, Native ARM64 is the winning moveIf you rely on legacy software and heavy creative workloads, emulation tides you over until native builds arrive, and in some cases an x86 computer will still make sense until the transition is complete.
The current photograph makes it clear that the Windows 11 and ARM tandem has ceased to be an experiment And it's moving forward steadily, with increasingly comprehensive native catalogs, more refined emulation thanks to Prism and ARM64EC, and developer support that drives adoption. Choosing wisely between native and emulated, depending on your apps and your way of working, is the key to making the most of the autonomy and performance offered by this platform.
