As cloud computing and virtualization evolve, the choice between ARM-based VPS (Virtual Private Server) and x86-based VPS has become an important consideration for developers, businesses, and enterprises. ARM architecture, once dominant in mobile and embedded systems, is now challenging x86 architecture in the cloud computing space due to its power efficiency, cost-effectiveness, and performance improvements.
This article provides an in-depth comparison of ARM VPS vs x86 VPS, discussing their architecture, performance, pricing, compatibility, and best use cases. By the end, you’ll have a clear understanding of which VPS type is best suited for your needs.
Understanding ARM and x86 Architectures
What is ARM Architecture?
ARM (Advanced RISC Machine) is a Reduced Instruction Set Computing (RISC) architecture designed for power efficiency and optimized performance. It powers most modern smartphones, tablets, and an increasing number of data center servers. ARM-based VPS solutions are gaining traction due to their lower energy consumption and competitive processing power.
Key Features of ARM Architecture:
- Energy-efficient design
- High performance per watt
- Lower heat generation
- Ideal for cloud-native applications
What is x86 Architecture?
x86 is a Complex Instruction Set Computing (CISC) architecture developed by Intel and AMD, traditionally used in PCs, laptops, and data centers. It has been the industry standard for VPS hosting for decades, offering wide software compatibility and robust performance.
Key Features of x86 Architecture:
- Optimized for general-purpose computing
- Strong support for legacy applications
- High single-threaded performance
- Used by most traditional cloud providers
Performance Comparison: ARM VPS vs x86 VPS
Processing Power
- ARM VPS: ARM CPUs generally have lower clock speeds but are designed for parallel processing, making them efficient for workloads that scale across multiple cores.
- x86 VPS: Offers higher single-threaded performance, which benefits applications that rely on raw processing power rather than multi-threading.
Power Efficiency
- ARM VPS: ARM processors consume significantly less power than x86, making them cost-effective for cloud providers and users who prioritize energy savings.
- x86 VPS: While more powerful, x86 CPUs require higher power consumption and generate more heat, leading to higher operational costs.
Virtualization & Cloud Optimization
- ARM VPS: ARM-based servers are optimized for cloud-native applications, including containerized workloads (Docker, Kubernetes).
- x86 VPS: x86 servers still lead in traditional virtualization environments such as VMware, KVM, and Hyper-V.
Software Compatibility: Which One Supports More Applications?
Operating System Support
| OS | ARM VPS | x86 VPS |
|---|---|---|
| Linux Distros (Ubuntu, Debian, CentOS) | ✅ Yes | ✅ Yes |
| Windows Server | ❌ Limited Support | ✅ Full Support |
| macOS | ❌ No | ❌ No |
| BSD (FreeBSD, OpenBSD) | ✅ Yes (Some Support) | ✅ Yes |
ARM VPS Limitation: If you need Windows-based applications, ARM VPS is not the best option since Windows Server support is limited.
Application Compatibility
| Software Type | ARM VPS | x86 VPS |
|---|---|---|
| Web Servers (Nginx, Apache) | ✅ Yes | ✅ Yes |
| Databases (MySQL, PostgreSQL) | ✅ Yes | ✅ Yes |
| Containerization (Docker, Kubernetes) | ✅ Yes | ✅ Yes |
| Cloud Platforms (AWS, Azure, GCP) | ✅ Yes | ✅ Yes |
| Legacy Software | ❌ No | ✅ Yes |
Cost Comparison: Is ARM VPS More Affordable?
- ARM VPS is often cheaper than x86-based VPS because ARM processors consume less energy and have lower cooling requirements.
- Many cloud providers (AWS, Oracle, Scaleway, etc.) offer ARM-based VPS at a reduced price compared to x86 servers.
- Licensing costs for Windows Server and proprietary software are typically higher for x86 systems.
Key Takeaway: If you’re looking for a budget-friendly solution for Linux-based applications, ARM VPS is the more economical choice.
Best Use Cases for ARM VPS and x86 VPS
When to Choose ARM VPS?
✔ Cloud-Native Applications (Microservices, Serverless Computing)

Which VPS Should You Choose?
| Factor | ARM VPS | x86 VPS |
|---|---|---|
| Performance | ✅ Great for multi-core workloads | ✅ Better single-threaded performance |
| Power Efficiency | ✅ More energy-efficient | ❌ Higher power consumption |
| Software Compatibility | ❌ Limited for Windows apps | ✅ Works with most software |
| Pricing | ✅ More affordable | ❌ More expensive |
| Virtualization | ✅ Optimized for containers | ✅ Works well with VMs |
| Gaming Servers | ❌ Limited support | ✅ Better for gaming |
Final Verdict
- Choose ARM VPS if you prioritize power efficiency, cost savings, and cloud-native applications.
- Choose x86 VPS if you need maximum software compatibility, Windows applications, or higher single-core performance.
ARM vs X86 : Conclusion
The competition between ARM VPS and x86 VPS is reshaping the VPS hosting industry. While x86 remains the dominant choice for traditional computing needs, ARM-based VPS is rapidly growing due to its efficiency and lower costs.
If your workload is cloud-native, containerized, or Linux-based, ARM VPS offers significant advantages. However, if you rely on legacy applications, Windows environments, or high-performance computing, x86 VPS remains the better option.
By carefully evaluating your use case, budget, and software requirements, you can make the right decision between ARM and x86 VPS for your business.
