A New Era for ARM on Windows

For years, Windows on ARM was a compelling idea held back by performance and compatibility limitations. The Qualcomm Snapdragon X Elite and Snapdragon X Plus, released in 2024, changed that narrative significantly. These chips — built on a custom ARM-based CPU core called Oryon — are the first Snapdragon processors designed specifically for premium Windows PC competition, not repurposed mobile silicon.

The Oryon CPU: Custom ARM Cores

Unlike previous Snapdragon PC chips that used Cortex-based designs licensed from ARM, the Snapdragon X series uses Qualcomm's in-house Oryon CPU cores, developed largely by the team Qualcomm acquired from Nuvia. This matters for several reasons:

  • Higher single-thread performance: Oryon cores deliver meaningfully higher per-core performance than previous Snapdragon laptop designs
  • Larger caches: Substantial L2 and L3 cache configurations reduce memory bottlenecks for compute workloads
  • Custom branch prediction and prefetch: Oryon's microarchitecture is optimised for the highly variable workloads of a general-purpose PC OS

The Integrated NPU: AI on ARM

Both Snapdragon X variants include a powerful Neural Processing Unit (NPU) rated at 45 TOPS (Tera Operations Per Second). This makes these devices Copilot+ PC certified — Microsoft's designation for AI-capable PCs. The NPU enables:

  • Windows Recall (where available) — semantic search of your PC activity history
  • Live Captions with real-time translation — on-device language translation in any app
  • AI-enhanced image generation in Paint and Photos apps
  • Studio Effects — real-time background blur, eye contact correction, voice focus in video calls
  • Third-party AI acceleration in apps like Adobe Photoshop

Connectivity: An Integrated Platform Advantage

A key advantage of the Snapdragon X platform is the depth of its integrated connectivity stack, which comes directly from Qualcomm's mobile heritage:

  • Wi-Fi 7 (802.11be) integrated — the fastest widely-supported Wi-Fi standard
  • Bluetooth 5.4 integrated
  • Optional 5G modem integration — select devices offer Sub-6GHz and mmWave 5G
  • USB4 / DisplayPort 2.1 support for high-bandwidth external displays

Power Efficiency and Thermal Design

The Snapdragon X series is designed for fanless or low-noise thin-and-light form factors. Many devices can sustain substantial workloads in fanless configurations — something that was rare in competing x86 ultrabooks. TSMC's 4nm process node underpins the efficiency gains.

Battery life claims from OEMs using Snapdragon X chips have been among the highest ever reported for Windows laptops in independent testing, frequently exceeding many competing x86 ultrabooks in real-world mixed workloads.

The Competitive Landscape

The Snapdragon X series competes directly with Apple Silicon (M-series chips) in terms of efficiency and integrated platform design. While direct performance comparisons depend heavily on workload and the specific benchmark, the gap between Apple Silicon and ARM-based Windows has narrowed substantially compared to earlier Snapdragon generations.

Intel and AMD have also responded with their own efficiency-focused architectures, meaning the overall Windows laptop market is seeing genuine competition on power efficiency for the first time in years — a development that benefits all Windows users.

What This Means for the WoA Ecosystem

The commercial success and critical reception of Snapdragon X devices has directly accelerated ARM64 app porting efforts across the software industry. More developers now prioritise ARM64 Windows builds, driver support has improved, and Microsoft's own Windows investment in ARM has visibly increased. The Snapdragon X series has, in a real sense, turned Windows on ARM from a niche experiment into a mainstream platform.
