A hands-on comparison of Windows Server 2025 running in Hyper-V on a Snapdragon X Elite (ARM64) versus a 14th Gen Intel Core i9 (x64). Using Performance Monitor counters and PowerShell benchmarks for IIS, DNS, Active Directory, and file I/O, the ARM64 setup consistently showed lower latency, flatter CPU utilization, zero processor queue length, and more predictable scheduling. The author attributes this to ARM's sustained clock behavior versus Intel's boost/throttle pattern, plus a potentially cleaner ARM64 Windows Server build. The conclusion is that for latency-sensitive, virtualized Windows Server workloads, ARM64 consistency beats x64 peak throughput — though x64 remains the practical choice for teaching due to lack of nested virtualization support on ARM64 Hyper-V.
