Nvidia and Microsoft are plotting a full-scale assault on the PC processor market at Computex 2026. On Monday, June 1, the world’s most valuable chip designer is expected to lift the curtain on its first Arm-based system-on-chips designed specifically for Windows 11 laptops and desktops. Behind the scenes, Microsoft, Dell, and the Surface engineering team are reportedly lined up to throw their weight behind the launch, signaling that the era of exclusive Qualcomm dependence for Windows on Arm could finally be coming to an end.

Industry insiders say the announcement is slated for 10:30 a.m. Taipei time during the Computex CEO keynote, delivered jointly by Nvidia co-founder Jensen Huang and Microsoft Devices chief Panos Panay. The event will showcase reference designs from Dell and a next-generation Surface Pro 11 powered entirely by Nvidia silicon, sources familiar with the plans told reporters. It marks the first tangible proof that Arm-based Windows PCs will become a true multi-vendor market after years of promise.

The Long Road to Windows on Arm

Microsoft has been trying to make Arm-powered PCs happen for more than a decade. The first Windows RT devices, launched alongside Windows 8 in 2012, ran on Nvidia’s Tegra 3 chips. But the software ecosystem was barren, and the performance couldn’t match Intel’s Core series. The Surface RT flopped. Microsoft rebooted the effort in 2017 with Windows 10 on Arm and Qualcomm’s Snapdragon 835, followed by exclusive partnerships for the SQ1 and SQ2 custom chips in the Surface Pro X. Those too suffered from sluggish emulation of x86 apps and a dearth of native Arm software.

Everything changed in late 2023 when Qualcomm delivered the Snapdragon X Elite, a laptop chip with performance that finally rivaled Apple’s M2. Microsoft’s exclusivity deal with Qualcomm, which prevented other silicon vendors from shipping Windows on Arm PCs, expired in early 2024. Since then, the company has been readying an open platform for Arm chips from any vendor willing to build compliant hardware and drivers. Nvidia’s entry is the most consequential test of that openness.

Why Nvidia Now?

Nvidia has been circling the PC market for years. Its Grace-Hopper supercomputer chips already proved the company can build high-performance, power-efficient Arm cores. A consumer-focused processor would leverage the same building blocks—custom Neoverse-based CPU cores, a scaled-down version of the Blackwell GPU architecture, and dedicated AI engines for on-device inferencing. Leaked benchmarks suggest a 12-core CPU cluster running at up to 3.8 GHz, paired with a 40-core integrated GPU capable of 8 teraflops of FP32 compute. That’s enough muscle to handle AAA gaming at 1080p, creative workloads like 4K video editing, and local AI models with billions of parameters.

But the real differentiator is Nvidia’s AI software stack. The chip will ship with CUDA acceleration for Windows on Arm, allowing developers to tap into the same parallel computing platform that dominates data centers and AI research. Nvidia is also preparing an Arm-native version of its RTX development kit, ensuring that games and professional apps can access hardware ray tracing and DLSS upscaling from day one. Microsoft has already integrated Nvidia’s AI frameworks into Windows Studio Effects, Copilot runtime, and the DirectML API.

Multi-Vendor Ecosystem Takes Shape

Until now, Windows on Arm has meant exactly one chip family: Qualcomm Snapdragon. That left PC makers with no fallback if performance, supply, or pricing disappointed. With Nvidia in the game, device manufacturers gain leverage to negotiate better deals and differentiate their products. Samsung, MediaTek, and even AMD are also working on Arm-based PC chips, according to industry sources, though none are expected to be ready before 2027. For the next 18 months, the Arm PC market will be a two-horse race between Qualcomm’s Snapdragon X series and Nvidia’s new platform, codenamed “Grace Desktoppe” internally.

Dell has already committed to shipping Latitude and XPS laptops built around the Nvidia chip by the 2026 holiday season, prioritizing AI tasks that run locally rather than in the cloud. Lenovo, Asus, and HP are evaluating the platform for their premium lines. Perhaps most telling is Microsoft’s own Surface division. The company is expected to move the entire Surface Pro and Surface Laptop lineup to Nvidia silicon over the next two product cycles, abandoning Qualcomm for its hero devices.

The App Compatibility Question

Any Arm PC lives or dies by its ability to run legacy Windows software. Microsoft’s Prism emulator, introduced with Windows 11 24H2, has made remarkable strides, running x86-64 binaries at about 85% of native speed and with broad compatibility. But gaps remain. Adobe’s Creative Suite still lacks native Arm versions of After Effects and Premiere Pro, forcing creative professionals to rely on emulation. Many AAA games still use anti-cheat drivers incompatible with Arm. Nvidia’s driver team is working with game studios to port anti-cheat middleware, and Microsoft has pledged an Arm-native version of the Windows SDK for game developers by mid-2026.

For enterprise software, the situation is brighter. Microsoft 365, Teams, Chrome, Firefox, and Visual Studio are all Arm-native. Salesforce, SAP, and many line-of-business apps have published Arm64 builds over the past year. With Nvidia’s CUDA support, data science tools like Python, TensorFlow, and PyTorch will run at full speed without emulation. This alone could make Arm laptops attractive to developers and AI engineers who have been stuck on MacBooks or heavy x86 workstations.

A Threat to Wintel Dominance

Intel and AMD are watching the Computex announcement with understandable anxiety. The Wintel partnership that defined the PC industry for 40 years is fraying. Intel’s latest Lunar Lake processors offer competitive battery life and AI performance, but they are built on the same x86 foundation that cannot match Arm’s efficiency in fanless, always-connected devices. AMD’s Ryzen AI 300 series is powerful, but the company’s Arm ambitions remain murky. If Nvidia can deliver performance per watt that exceeds x86 while offering a seamless software experience, enterprise IT buyers—who have long prioritized manageability and security—may finally make the switch.

Microsoft’s own Copilot+ PC branding, originally tied to Qualcomm, will extend to Nvidia-powered devices with even more AI capabilities. These machines will run Windows 11 25H2, featuring an overhauled AI subsystem that can offload tasks like real-time translation, video summarization, and code generation to the Nvidia GPU. The combination of Microsoft software and Nvidia hardware could create a platform that rivals Apple’s tightly integrated M-series ecosystem.

What to Expect at Computex

The Computex keynote is expected to last 90 minutes and will include live demos. Huang is slated to showcase a reference laptop running Cyberpunk 2077 at 60 fps using DLSS 4 and ray tracing. Panay will demonstrate how Copilot integrates with Nvidia’s AI engine to analyze email threads and generate presentations locally, without sending data to the cloud. The Dell prototype will feature a 13-inch bezel-less OLED display and battery life north of 20 hours. A Surface Pro 11 prototype will be shown with a detachable keyboard and Pen support.

Pricing and specific SKUs will not be announced until later in the year, but Nvidia is positioning its platform as a premium alternative to Qualcomm, with chips likely to land in devices ranging from $1,200 to $2,500. Linux support is also planned, with Nvidia contributing Arm kernel patches and open-source GPU drivers to the Linux community, making the platform attractive for dual-boot Windows-Linux machines.

The Road Ahead

A multi-vendor Arm ecosystem would fundamentally reshape the Windows PC landscape. It would break Qualcomm’s monopoly on Windows on Arm, force Intel and AMD to accelerate their own innovation, and give consumers a genuinely compelling alternative to Apple Silicon. History suggests the transition won’t be smooth. Early adopters will face driver bugs, incompatible peripherals, and gaps in the app gallery. But the technology foundation—fast Arm cores, robust GPU acceleration, native AI frameworks, and improved emulation—is stronger than ever.

Microsoft’s biggest challenge is not hardware but developer conviction. It must convince software makers that Arm PCs are a permanent, growing segment worth investing in. Nvidia’s developer relations muscle, honed over two decades of CUDA evangelism, could tip the balance. If enough ISVs ship Arm64 builds this year, the 2027 PC market could look dramatically different than it does today. For now, all eyes are on Taipei. Monday morning’s announcement will set the direction for Windows computing for the rest of the decade.
