ARMed and dangerous: server wars ignite
Windows Server 2025 Runs Better on ARM
ARM laptop beats pricey Intel rig — and the comments go feral
TLDR: A lab test found Windows Server 2025 VMs felt faster on a Snapdragon X Elite (ARM) than on a Core i9 (Intel), likely thanks to steadier performance and a cleaner ARM build. Comments split fast: x86 tweakers say tune power settings, Linux fans say ditch Windows, and devs point to memory optimizations.
A Windows Server pro spun up the same Windows Server 2025 lab on two machines — a high‑end Intel Core i9 PC and a Snapdragon X Elite ARM laptop — and ARM felt snappier. Services like Active Directory launched quicker, consoles popped open faster, and tasks just finished sooner. The author credits ARM’s steady, no‑drama performance and hints that the ARM64 build of Windows Server might be cleaner and more modern than the x64 one. Cue the internet brawl.
On one side, tuner types like p_ing say Intel can hang if you flip the right switches: crank power settings, kill “C states” (power‑saving modes), and stop the chip from yo‑yoing — just not on a home lab. On the other, Linux diehards pile in: stackskipton declares Microsoft’s server future is basically Linux, while bfrog jokes Windows is wasting cycles “spying.” phwbikm brings the heat with, “Who even uses Windows Server anymore?” Meanwhile, a Windows dev (kh9000) offers a nerdy twist: it might be segment heap — a newer memory system — plus fewer legacy layers on ARM, quietly making everything smoother.
Also stirring the pot: Microsoft doesn’t even offer an official ARM Server 2025 installer; the author used UUP dump. The vibes? ARM is the shiny new speedster, x86 loyalists say “tune it,” Linux fans say “just switch,” and everyone else is here for the memes and the benchmarks. For the curious: Windows Server, ARM, Hyper‑V
Key Points
- •The author deployed identical Windows Server 2025 VM environments on two Windows 11 hosts: Intel Core i9 (x64) and Snapdragon X Elite (ARM64), using Hyper-V.
- •Because Microsoft offers no official Windows Server 2025 ARM64 ISO, the author created one via UUP dump from Microsoft’s update servers.
- •In practical use, the ARM64 setup felt faster: services (e.g., Active Directory) started sooner, consoles opened quicker, and tasks completed in less time.
- •The article attributes perceived gains to steady ARM performance versus frequency variability on modern Intel CPUs, which can affect latency and scheduling under mixed/sustained loads.
- •Predictable hardware timing benefits hypervisors like Hyper-V, and the ARM64 Windows Server build may be more modern with fewer legacy layers; initial Performance Monitor measurements were started.
