The laptop industry is undergoing a major transformation in 2025, driven by two powerful forces: ultracompact form factors and the widespread adoption of ARM-based processors. These devices are not just thinner and lighter—they’re smarter, more energy-efficient, and more capable than ever before.
This year marks a pivotal moment where ultracompact laptops powered by ARM chips are no longer niche alternatives, but serious contenders to dominate mainstream and even enterprise markets. With Apple, Qualcomm, Microsoft, Lenovo, and Samsung leading the charge, the ultracompact ARM laptop is becoming the new standard for mobile productivity.
In this article, we will explore the evolution of ARM chips, the design breakthroughs enabling ultracompact laptops, the leading models in 2025, their advantages, software compatibility, and what the future holds.
1. What Are ARM Chips, and Why Do They Matter?
ARM (Advanced RISC Machines) is a processor architecture known for its low power consumption, smaller physical footprint, and scalability. Originally developed for mobile devices like smartphones and tablets, ARM chips have steadily made their way into laptops and desktops over the past decade.
In contrast to traditional x86 processors (from Intel and AMD), ARM chips follow a RISC (Reduced Instruction Set Computing) design philosophy, which leads to greater energy efficiency and longer battery life.
Key reasons why ARM is reshaping laptops in 2025:
- Efficiency-first design leads to battery lives exceeding 20 hours.
- Integrated AI acceleration with built-in NPUs (Neural Processing Units).
- Smaller logic boards, allowing thinner devices with less heat.
- Rapid development of native software and emulation layers, reducing compatibility gaps.
2. Why “Ultracompact” Is the New Norm
Today’s consumers and professionals expect their devices to be:
- Portable enough to carry all day
- Capable enough to handle productivity, video editing, and multitasking
- Quiet and cool with no noisy fans
- Stylish, minimalist, and futuristic in design
Ultracompact laptops, defined by being under 1.2kg in weight and less than 15mm in thickness, are rising to meet these demands.
What enables this new ultracompact form?
- ARM processors run cool and don’t need heavy cooling systems.
- Solid-state storage and battery improvements free up internal space.
- High-efficiency OLED displays use less energy and thinner layers.
- Slim motherboards mean more room for batteries.

4. Software Compatibility: Still a Concern?
One of the biggest historical concerns about ARM-powered laptops has been software compatibility. In 2025, this is no longer a significant issue thanks to:
- Microsoft’s native ARM64 Windows 11 experience, with major apps like Office, Teams, Chrome, Edge, Adobe Creative Suite running natively.
- Rosetta 2 and Universal apps in macOS, ensuring smooth emulation on Apple silicon.
- AI-powered emulation engines reducing the performance gap when running x86-only apps.
Additionally, developers are now prioritizing cross-platform builds, and many frameworks (Electron, Flutter, .NET MAUI, Unity) offer native ARM support.
