Dedicated server hosting is changing. For decades, x86 processors dominated data centers. Intel and AMD chips powered everything from small business servers to massive enterprise infrastructure. That monopoly is ending.
ARM-based servers are entering the market. Major cloud providers already use them.
The global ARM-based servers market, valued at $5.84 billion in 2023, is expected to reach $14.51 billion by 2030, growing at a compound annual rate of 13.9%. This rise stems from ARM’s energy efficiency and cost advantages, challenging traditional x86 dominance.
This guide explains ARM-based hosting dedicated servers, their advantages over traditional hosting, and how they fit into your business strategy.
What Are ARM-Based Dedicated Servers?
ARM-based dedicated servers use processors built on ARM architecture. ARM stands for Advanced RISC(Reduced Instruction Set Computing) Machine. These processors break complex operations into multiple simpler instructions. Originally designed for mobile devices and embedded systems, ARM chips prioritized energy efficiency over raw power.
ARM-based dedicated servers combine these two concepts. You get a complete dedicated server powered by ARM processors instead of x86 chips. Examples include AWS Graviton processors, Google Axion, and Microsoft Cobalt CPUs.
x86 architecture (Intel and AMD chips) uses CISC (Complex Instruction Set Computing). These processors handle complex instructions in single operations. They’ve dominated servers since the 1990s because software was built specifically for them.
Why ARM Architecture Matters
ARM processors were designed for efficiency. They consume less power while delivering high performance. Each processor core handles one task at a time, with no hyperthreading. This means every vCPU is backed by a full physical core.
ARM in Dedicated Server Hosting
Dedicated server hosting means you rent an entire physical server. No sharing resources with other users. Complete control over configuration and software.
ARM-based dedicated servers work identically to traditional dedicated servers in concept. The difference lies in the processor architecture powering them.
When you rent an ARM dedicated server, you get:
- Entire physical server with ARM processors
- Full root access and control
- Dedicated resources (CPU, RAM, storage, bandwidth)
- Isolated environment separate from other users
The hosting experience remains familiar. The underlying hardware architecture changes.
Current State of ARM Server Adoption
ARM servers aren’t theoretical. Major companies already deploy them at scale.
The ecosystem has evolved rapidly in the last 12 months. It is no longer just an AWS game.
- Google Axion (GA 2024): Google’s custom ARM chip has entered General Availability, outperforming comparable x86 instances by up to 50% and offering 60% better energy efficiency.
- Microsoft Cobalt 200 (Late 2025): Just announced, this chip features 132 cores and targets massive scale-out cloud-native workloads, proving that Azure is moving its internal infrastructure (Teams, SQL) to ARM.
