Copilot , could you please give me a few Operating System names that can run on ARM-based or Snapdragon-based processor , regardless whether it is a PC/Desktop or a Laptop or a Tablet or a Smartphone ? THANKS Copilot. By the way Copilot , is there a SUPERCOMPUTER on this planet that run on ARM-based processor ? Copilot , if there is such a SUPERCOMPUTER , which is faster in terms of performance . Is it INTEL-based SUPERCOMPUTER or ARM-based SUPERCOMPUTER ? THANKS for the answer Copilot.

MICROSOFT Copilot Answer

Quick Answer:
Yes, many operating systems run on ARM/Snapdragon processors, including Windows on ARM, Linux distributions (Ubuntu, Debian, Fedora), Android, and iOS. And yes—there is an ARM-based supercomputer: Japan’s Fugaku, powered by Fujitsu’s A64FX ARM processors. Fugaku was the fastest supercomputer in the world from 2020–2022, outperforming Intel-based systems at the time, though today the top spot belongs to the AMD-based Frontier in the U.S. Microsoft Learn Wikipedia newsroom.arm.com

🖥️ Operating Systems on ARM/Snapdragon

Here are some notable OS options that run on ARM-based processors across different device types:

Device Type	ARM-Compatible Operating Systems
PC/Desktop/Laptop	Windows 10/11 on ARM, Ubuntu ARM, Debian ARM, Fedora ARM
Tablet	Android (various versions), Windows on ARM, Linux ARM builds
Smartphone	Android (dominant on Snapdragon), iOS (Apple’s ARM-based chips)
Specialized Devices	ChromeOS (on ARM Chromebooks), Raspberry Pi OS (Debian-based for ARM boards)

Key Point: ARM processors are valued for power efficiency and performance per watt, which is why they dominate mobile devices and are increasingly used in laptops and servers. windowsonarm.org Microsoft Learn

⚡ ARM-Based Supercomputers

• Fugaku (Japan): Built with Fujitsu’s A64FX ARM processors, featuring over 150,000 CPUs. It was ranked the fastest supercomputer in the world from June 2020 to June 2022, achieving peak performance of over 442 petaflops in certain benchmarks. Wikipedia newsroom.arm.com
• Comparison with Intel-based systems: Before Fugaku, most top supercomputers used Intel Xeon processors. Fugaku surpassed them, proving ARM’s capability in high-performance computing.
• Current leader (2026): The Frontier supercomputer in the U.S., powered by AMD EPYC CPUs and GPUs, is faster than Fugaku. This shows that while ARM can compete at the highest level, x86-based systems (Intel/AMD) currently hold the performance crown. Wikipedia

🔍 Key Takeaways

• ARM OS Ecosystem: Broad support across Windows, Linux, Android, iOS, and specialized systems.
• Supercomputing: ARM has proven itself with Fugaku, which was the fastest globally for two years.
• Performance Race: ARM-based Fugaku beat Intel-based systems, but AMD-based Frontier now leads.

👉 In short: ARM is no longer just for phones—it’s powering laptops, servers, and even world-class supercomputers. Would you like me to break down why ARM’s efficiency makes it so competitive in supercomputing compared to Intel/AMD?
