✦ Snapdragon X and the PC Nobody Has WonThin moat

Qualcomm (QCOM) — the future bets

The best hand Qualcomm has ever held against a compatibility moat that has beaten Arm on Windows since 2012.

Qualcomm has been trying to put Windows on Arm for over a decade, and this is the best hand it has ever held.

The best hand Qualcomm has held against a moat that has beaten it three times.

Snapdragon X uses the Oryon cores that came with the 2021 Nuvia acquisition — a CPU team from the server world, designing for performance rather than for phone power envelopes. The product is genuinely competitive on battery life and increasingly on performance, and Qualcomm now has clear legal title to it: Arm's challenge was dismissed in full in September 2025 after a December 2024 jury verdict, with an appeal promised.1

The obstacle has never been the silicon. Windows on Arm has failed since 2012 because x86 software compatibility is a moat belonging to Intel and AMD, and emulation has always been the compromise that loses the sale. Apple solved the identical problem by owning the operating system and forcing the transition. Qualcomm cannot.

What is different now is that the buyer has a new reason to care. On-device AI needs the NPU more than the CPU, and that is a specification where Qualcomm starts even or ahead — which is why Microsoft built its Copilot+ requirements around it.

The scale is still small: PCs sit inside the $6.6 billion IoT line rather than warranting their own disclosure.2

The measure is Arm's share of Windows PC shipments, which is where a decade of failure would finally break.3

Moat trajectory: Holding steady

Snapdragon X exists, the legal title to Oryon is settled, and Arm-based Windows still has not displaced x86. Nothing has moved in either direction.

The number that tests this moat

IoT revenue
$1,830M in Q3 fiscal 2026, +9%

Snapdragon X PC chips are reported within IoT, alongside other devices. Faster growth in this line would be the first sign that Windows PCs on Arm are selling in volume.
