Nvidia CEO Jensen Huang introduced the RTX Spark laptop processor during his Computex 2026 keynote in Taipei on June 1, 2026, marking the company's first major entry into the mainstream PC processor market. The RTX Spark superchip, also referred to as the N1X, will debut in fall 2026 on a new line of Windows PCs from Microsoft, Dell, HP, ASUS, Lenovo, and MSI.
Unified Architecture Enables 120B Parameter Models Locally
The RTX Spark is an Arm-based chip that integrates a 20-core Grace CPU (built alongside MediaTek), a Blackwell RTX GPU with 6,144 CUDA cores, an NPU, and up to 128GB of unified LPDDR5X memory, all on a single TSMC 3nm package. This architecture enables devices to run massive 120-billion parameter AI models locally without needing cloud connectivity.
The unified memory architecture allows seamless data sharing between CPU and GPU, which Nvidia positioned as enabling Windows to become an "agentic AI OS." The company expects more than 30 laptops and 10 desktops to ship with the new chipline.
Nvidia Challenges Intel, AMD, and Qualcomm in PC Market
The announcement represents Nvidia's expansion into a market long dominated by Intel, Advanced Micro Devices, Qualcomm, and Apple. By combining their GPU expertise with an Arm-based CPU architecture designed for AI-driven computing, Nvidia is betting on AI workloads becoming central to personal computing.
Nvidia also outlined a three-generation roadmap: RTX Spark (N1X) launching in fall 2026, followed by Rubin with LPDDR6 memory, and then Rosa Feynman. This roadmap signals the company's long-term commitment to the PC processor market beyond the initial RTX Spark launch.
