- ARM and x86 architectures differ in their instruction set, power impact, and performance.
- Windows on ARM it offers great efficiency, but has limitations in compatibility with software and peripherals.
- x86 emulation on ARM devices has improved, but it is still not perfect for all applications.
- New ARM processors like the Snapdragon X Elite offer competitive performance and longer battery life.
In an increasingly diverse technological world, choosing between devices with ARM or x86 processors to run Windows can generate more than one doubt. In recent years, with the rise of portable ultra-thin and the need for greater autonomy, the ARM architecture has gained strength against the traditional dominance of x86 Intel and AMD.

With advances like Qualcomm's Snapdragon X Elite chips and Apple's clear example with its M1, M2, and M3 processors, the gap between power and energy efficiency has become a key point when deciding what type of processor you need. But is it really worth it to go for a Windows laptop on ARM? Or are x86 compatibility and performance still unbeatable for certain uses?
Technological differences between ARM and x86
To understand why there are different versions of Windows depending on the processor type, it is essential to understand how the ARM and x86 architectures differ. The main difference lies in their instruction set. x86 processors use a CISC (Complex Instruction Set Computer) architecture, which allows complex tasks to be performed in fewer lines of code, although at the cost of greater complexity. hardware and energy consumption.
By contrast, ARM processors are based on the RISC (Reduced Instruction Set Computer) architecture, which means its instructions are simpler and require fewer cycles to execute. This simplicity allows for the design of smaller chips with fewer transistors and less heat generation, which translates into greater energy efficiency.
Thanks to this efficiency, ARM chips are ideal for mobile devices and ultra-thin laptops, while x86 chips continue to dominate in environments where maximum performance and compatibility with traditional software are essential, such as desktop PCs and workstations.

Advantages of Windows on ARM
Since its first foray in 2012 with Windows RT, Microsoft has progressively worked to make its operating system more competitive on ARM architectures. The real evolution has come with Windows 11 and the new Snapdragon processors, which now offer a much more complete experience.
Some of the notable benefits of Windows on ARM include:
- Superior energy efficiency: ARM devices consume much less power, allowing for battery life of up to 20 hours under optimal conditions.
- Thinner, fanless devices: Because they generate less heat, many ARM-based laptops do not require active cooling systems.
- Instant on and permanent connection: Thanks to their mobile-like design, they support LTE/5G connectivity and activate instantly.
In addition, Microsoft has developed an emulation layer called Prism, which allows you to run x86 (32-bit) applications on ARM devices. While it's not perfect, it has improved a lot in recent years.

Practical limitations that you should take into account
Windows on ARM still has certain limitations that shouldn't be overlooked, especially if you rely on very specific software or are using older hardware. The most critical is compatibility with applications and drivers.
- It is not possible to run x64 (64-bit) applications that do not have an ARM version.Microsoft is working on improving emulation, but at the moment only the apps x86 (32-bit) can be emulated.
- Some professional editing programs, video games and advanced technical software do not work, or work poorlyGames with anti-cheat systems are also affected.
- Controller support is limited to drivers ARM64, which means that peripherals without those drivers (for example, older printers) may not work.
- Hyper-V and other native Microsoft virtualization technologies are not supported., which can be a barrier for advanced users.
Microsoft and developers are progressively expanding the catalog of apps optimized for ARM. In fact, apps like Microsoft Office 365, Outlook, Teams, Edge, Zoom, WhatsApp, Spotify and Blender already have native versionsTo check the compatibility of specific apps, you can visit the site worksonwoa.com.
Real performance: ARM is no longer just about efficiency
For years it was assumed that ARM chips were synonymous with modest performance. That changed with the Arrival of Apple's M processors and, more recently, with the Snapdragon X Elite and X Plus from QualcommThe latter have come to surpass many conventional x86 CPUs in performance per watt, making them a real alternative when using Windows.
These new processors integrate advanced features such as neural processing units (NPUs) designed for computing tasks. Artificial Intelligence, which improves applications such as real-time translation, noise removal, and contextual search.
For office tasks, general productivity, and even basic video or photo editing, the performance is more than sufficient.. However, if your usage involves running complex AutoCAD, After Effects, or engineering simulation projects, x86 is still the best bet.

Available Windows ARM laptop models
Windows-based devices on ARM are gaining traction. Some models you might consider depending on your needs include:
- Microsoft Surface Pro X: 2-in-1 design, very lightweight, and with good battery life. A good choice for those who use Office and browse frequently.
- Lenovo ThinkPad X13s: Aimed at professionals, it offers 5G connectivity and outstanding battery life.
- Huawei MateBook E: stands out for its light weight, OLED screen and mobility-focused design.
In markets like Chile and Spain, these models are already available and are growing in popularity, especially in educational settings, mobile business environments, or for those seeking maximum autonomy.
Who should bet on Windows on ARM?
Choosing between a Windows ARM laptop or one with an x86 processor depends entirely on your needs. Here's a quick guide:
Who is ARM for?
- Professionals who prioritize mobility and autonomy, such as consultants, journalists or teachers.
- Students who need office tasks, web browsing and video calls.
- Users concerned about battery life or who travel frequently.
Who should avoid it?
- Gamers or creators of advanced multimedia contentPerformance and compatibility for modern video games is still limited.
- Users who use specialized software such as SolidWorks, MATLAB or AutoCAD if there is no ARM version.
- Corporate environments where the use of old drivers or outdated peripherals is common.
If you don't use very demanding or specific functions, a device with ARM architecture can give you a fluid, efficient experience with great battery advantages..
The ARM vs. x86 debate in the Windows world is more open than ever. ARM has come a long way since the days of Windows RT, and with the arrival of much more powerful and efficient processors, it has earned a place at the big table. However, the x86 universe remains the standard in compatibility and pure power, especially in demanding environments. The key is to understand your needs, verify the compatibility of the software you use, and assess what is more important to you: battery life and portability or maximum performance and full compatibility?
