NVIDIA will unveil its first Windows PC powered by the custom Arm-based N1X chip at Computex 2026 in Taipei and Microsoft's Build developer conference next week, according to multiple industry sources. The system-on-a-chip features a 20-core CPU, an integrated GPU on par with an RTX 5070, and a neural processing unit (NPU) exceeding 100 TOPS, far surpassing Microsoft's Copilot+ PC requirements. This marks a pivotal moment for Windows on Arm, as NVIDIA, the dominant force in AI and graphics, directly enters the PC processor market.

The 20-Core N1X Chip: Built on TSMC's 3nm Process with MediaTek

The N1X SoC, codenamed N1X, is manufactured on TSMC's 3nm process and co-developed with MediaTek. The chip combines Arm-based CPU cores with NVIDIA's Blackwell architecture for graphics, delivering desktop-class performance in a laptop form factor, as reported by industry sources.. MediaTek contributes its expertise in Arm SoC design, modem integration (including 5G), and power efficiency,while NVIDIA provides GPU, AI, and driver technologies. The partnership is expected to generate $2 billion in revenue for MediaTek in 2026 alone, according to supply chain sources cited by the report.

Microsoft's AI PC Strategy Gets a Second Chance After Qualcomm's Headwinds

Microsoft's initial push for AI PCs, centered on Qualcomm's Snapdragon X Elite chips, has faced limited software compatibility and lackluster gaming performance, the source notes . NVIDIA's entry offers a powerful reset by bringing decades of GPU driver optimization, a vast CUDA ecosystem,and unmatched AI capabilities. Microsoft is expected to announce deep integration of the N1X with Windows 12, including native support for NVIDIA's AI agent framework and real-time neual processing for features like Windows Studio Effects and on-device Copilot. Dr. Rakesh Kumar, a semiconductor analyst at ChipInsights, told the outlet: "NVIDIA brings instant credibility to Windows on Arm. Their GPU drivers alone could solve the compatibility issues that have held back the platform."

$2 Billion MediaTek Revenue and the Unnamed OEM Partners: Dell, Lenovo, ASUS, HP?

Industry analysts predict NVIDIA could capture 15-20% of the Windows PC market within two years, driven by partnerships with Dell, Lenovo, ASUS, and HP, according to the report. Dell is reportedly preparing a new XPS 16 model powered by the N1X, while Lenovo's ThinkPad X1 series and ASUS's ROG gaming line are also expected to feature the chip. however, the source does not name specific OEMs as confirmed partners for the initial launch, leaving open the question of which manufacturers will ship the first N1X devices and at what price point.

The Software Hurdle: x86 Emulation and Native App Compatibility Remain Unresolved

Despite the hardware prowess, NVIDIA faces significant software challenges. Windows on Arm still suffers from a limited native app library, and many x86 applications run poorly under emulation, as the source notes. NVIDIA must work closely with Microsoft to ensure compatibility with legacy software, especially in enterprise and creative workflows. Early reports indicate that popular games like Fortnite and Cyberpunk 2077 run at over 60 fps on N1X prototypes, but these claims are unverified by independent benchmarks. the chip's high performance may also come at a cost premium, potentially limiting its appeal to mainstream consumers. nVIDIA's driver team is developing a unified driver model that supports both x86 emulation and native Arm apps,but the timeline for seamless performance across all Windows applications remains unclear.
