Quick Answer:
x64 (also called AMD64 or Intel 64) is designed for powerful desktops and laptops.
It handles heavy software, games, and professional tools very well.
ARM64 is designed for efficiency.
It uses less power, runs cooler, and is perfect for laptops, tablets, and mobile devices.
Example:
If you’re running Photoshop, AutoCAD, or high-end games → x64
If you want long battery life and silent performance → ARM64
x64 or ARM64:
When choosing a computer, processor, or operating system, many people quickly run into one confusing question: x64 or ARM64?
The short and clear answer is this, x64 is better for compatibility and heavy desktop work, while ARM64 is better for battery life, efficiency, and modern mobile-style performance.
This single decision can affect how fast your system feels, which applications you can run smoothly, and how long your battery lasts during daily use.
That’s why so many people search for x64 or ARM64 when they see these terms on Windows downloads, Mac specifications, Linux installers, or software setup pages. At first, the names look technical and intimidating, but once you understand the basic difference, everything starts to make sense.
In this guide, I’ll explain it all in simple, everyday language so you can clearly see which option fits your needs and why it matters.
What Is x64?
x64 is a 64-bit processor architecture mainly used by Intel and AMD CPUs.
It evolved from older 32-bit systems to support more memory and better performance.
Most traditional computers today use x64.
Windows PCs, gaming rigs, office desktops, and workstations rely on it.
Key Traits of x64
- Excellent software compatibility
- Strong performance for heavy tasks
- Supports large amounts of RAM
- Widely used for decades
x64 is powerful, but it usually consumes more energy.
What Is ARM64?
ARM64 is also a 64-bit architecture, but it follows a different design philosophy.
It focuses on efficiency instead of raw power.
ARM64 is used in:
- Smartphones
- Tablets
- Apple Silicon Macs (M1, M2, M3)
- Windows on ARM laptops
ARM chips are designed to do more work using less power.
Key Traits of ARM64
- Excellent battery life
- Runs cooler and quieter
- Lightweight and efficient
- Growing software support
The Origin of x64 and ARM64
x64 comes from the x86 architecture, which started in the 1970s with Intel.
As software grew more complex, 64-bit support became necessary.
ARM, on the other hand, started in the 1980s with a focus on simplicity and efficiency.
That’s why ARM dominates mobile devices today.
The spelling difference exists because they are entirely different architectures, not variations of the same system.
x64 vs ARM64: Core Differences
Architecture Design
- x64 uses complex instructions
- ARM64 uses simple, efficient instructions
Performance Style
- x64 focuses on raw power
- ARM64 focuses on power efficiency
Comparison Table: x64 vs ARM64
| Feature | x64 | ARM64 |
|---|---|---|
| Performance | High raw power | Efficient and optimized |
| Battery Life | Lower | Much longer |
| Heat & Noise | Higher | Lower |
| Software Support | Very wide | Growing fast |
Software Compatibility: Which Runs More Apps?
This is where x64 still wins.
Most Windows and Linux software was built for x64 first.
Games, plugins, drivers, and professional tools usually support x64 natively.
ARM64 software is improving quickly, but some apps still rely on emulation.
Emulation Example
- Windows ARM can run x64 apps, but with a performance hit
- Apple Silicon uses Rosetta to translate x64 apps smoothly
Operating Systems: x64 or ARM64?
Windows
- x64: Best compatibility
- ARM64: Better battery life, limited drivers
macOS
- ARM64 (Apple Silicon): Optimized and fast
- x64 (Intel Macs): Older but compatible
Linux
- x64: Most supported
- ARM64: Great for servers and embedded systems
Which One Is Better for You?
Choose x64 If You:
- Use Windows desktop software
- Play PC games
- Use professional tools
- Need driver compatibility
Choose ARM64 If You:
- Want long battery life
- Prefer silent, cool devices
- Use modern apps
- Travel a lot
x64 or ARM64 for Developers
Developers need to think carefully.
x64 is still the safest option for:
- Legacy apps
- Cross-platform compatibility
ARM64 is ideal for:
- Mobile development
- Cloud servers
- Future-focused apps
Many developers now build for both.
x64 or ARM64 in Everyday Devices
Laptops
- Gaming laptops → x64
- Ultrabooks → ARM64
Servers
- Traditional servers → x64
- Cloud & energy-efficient servers → ARM64
Phones & Tablets
- Almost all → ARM64
Common Mistakes People Make
- Assuming ARM64 is weaker
- Thinking x64 is outdated
- Ignoring software compatibility
- Choosing based only on price
- Not checking OS support
Both architectures are modern and powerful—just built for different goals.
x64 or ARM64 in Real-Life Examples
Email:
