NVIDIA is poised to reshape the power structure of the PC industry with a single chip. On May 30th, it was noted that with just days remaining before the opening keynote of the Taipei Computex conference, NVIDIA's official social media account posted a three-word teaser: "A new era of PC."

The post also included two sets of geographic coordinates pointing to the Taipei Performing Arts Center. The official accounts for Microsoft Windows and Arm posted the same content on the same day.

This rare three-way collaboration brought a long-anticipated suspense to the forefront: NVIDIA is about to announce its entry into the Windows PC processor market. On the same day, citing informed sources, Axios reported that the first batch of Windows computers equipped with NVIDIA chips are expected to appear at both Computex and Microsoft's Build developer conference, with Microsoft's own Surface brand and Dell among them. Rumors about NVIDIA's Arm-based processors have circulated for some time. Dell CEO Michael Dell hinted in a 2024 interview that AI PCs equipped with NVIDIA chips might be launched in the future. NVIDIA's entry into the Windows on Arm platform signifies that Qualcomm will no longer hold the exclusive license for Microsoft's Windows 11 Arm operating system. For decades, NVIDIA's role in the PC supply chain has been that of a discrete graphics card supplier, "invited in" by OEMs to complete a precise component assembly task, without the authority to lead overall system design. Now, NVIDIA intends to integrate the CPU, GPU, and AI unit into a single SoC, directly supplying the "heart" to OEMs like Dell and Lenovo. This follows the vertical integration path of Apple's M-series, but with the entire Windows ecosystem as its target.

N1X Chip: A "Public Secret" Circulating for Nearly a Year

Speculation about this chip is not new. According to a previous report by The Wall Street Journal, manufacturers like Dell are developing laptop products equipped with N1 and N1X chips. According to VideoCardz, Lenovo was testing notebook prototypes using chips named N1 and N1X earlier this year. NVIDIA CEO Jensen Huang himself previously confirmed the company is developing the N1 chip, stating it belongs to the same technological lineage as the processor used in the DGX Spark mini-workstation. The latter is equipped with the GB10 super chip, which integrates a Blackwell architecture GPU with a 20-core Arm CPU. It is currently sold to AI engineers for $4,699. Current circulating specifications suggest the N1X may feature a 20-core CPU co-developed with MediaTek, a Blackwell architecture GPU with 6,144 CUDA cores (on par with the desktop RTX 5070), and support for up to 128GB of LPDDR5X unified memory architecture, allowing shared access by the CPU and GPU. This design philosophy is highly similar to Apple's M-series chips and Qualcomm's Snapdragon X series.

Windows on Arm: Transitioning from Qualcomm's Exclusive Hold to Multi-Party Competition

NVIDIA's entry will fundamentally alter the competitive landscape of Windows on Arm. Previously, Qualcomm's Snapdragon X series was the sole chipmaker licensed for the Windows Arm operating system, enjoying a de facto exclusive advantage. NVIDIA's joining means this exclusive license will officially end, ushering in genuine multi-party competition within the Windows Arm camp. However, Carolina Milanesi, an analyst at Current Strategies, stated that NVIDIA's entry is positive news for the entire industry and may also indirectly benefit Qualcomm. She pointed out that while Qualcomm previously held significant advantages in battery life, it failed to gain substantial market share in the PC market, partly because developers and enterprises were reluctant to invest resources specifically for a differentiated Windows version. NVIDIA's arrival could drive more developers to focus on the Windows on Arm ecosystem, thereby promoting overall platform maturity, from which Qualcomm could also benefit indirectly. This shift also carries Microsoft's strategic expectations. Microsoft's first major push for the AI PC concept, "Copilot+ PC," recently faced a series of setbacks, including the core Recall feature being delayed due to security concerns. Now, Microsoft hopes to run AI Agents on local devices, and the addition of NVIDIA, the world's hottest chipmaker, provides new endorsement for this agenda.

Beyond Chip Advantages, Gaming Scenarios Pose Potential Risks

Although the outlook for the N1X is quite optimistic externally, potential technical constraints cannot be ignored. Since the N1X uses the Arm architecture, running the x86 PC game library accumulated over decades will require reliance on an x86 emulation layer. According to PCWorld analysis, the existing Prism emulation layer in Microsoft Windows is specifically optimized for Qualcomm chips, with some performance features only effective on Snapdragon SoCs. This means the N1X may face performance degradation in gaming scenarios, or even have some games that simply cannot run. For a product positioning primarily focused on AI performance and battery life optimization, this limitation might not be a fatal flaw. However, NVIDIA currently positions itself more as an AI company than a graphics company. The core user groups targeted by the N1X—AI application developers and business users seeking thin, light, and long battery life—are distinctly different from gamers. The real market test will depend on the actual experience and pricing strategy of the first batch of N1X laptops upon release.

More Than Just a Chip Story

From a broader perspective, NVIDIA's entry into the PC processor market is a critical step in its transformation from a "component supplier" to a "platform definer." Historically in the PC supply chain, NVIDIA participated in the system ecosystem as a discrete graphics card supplier, with the overall architecture authority always held by Intel, AMD, and OEMs. By integrating the CPU, GPU, and AI unit into a single SoC, NVIDIA can directly supply OEMs with a complete core computing platform, fundamentally changing its position in the value chain. Apple has already created a successful template with this path using Apple Silicon. After Apple replaced Intel processors with its own Arm-based chips, Mac computers gained clear advantages in performance and battery life within the same price range, driving a continuous increase in Mac market share. The Windows camp has long hoped to replicate this path. Qualcomm's Snapdragon X series was the first attempt, and NVIDIA's N1X may be the most significant bet to date. However, the tech industry is never short of declarations of a "new era." Whether it can be fulfilled will only be known when consumers open a new generation of laptops a year from now. The answer will be officially revealed on June 1st, Beijing time.
