Nvidia Unveils RTX Spark Superchip for AI-Powered Windows PCs, Reshaping Consumer Computing

The Announcement

On June 1, Nvidia unveiled a powerful laptop chip for Windows machines, with CEO Jensen Huang announcing the RTX Spark Superchip at Computex 2026 in Taipei — a chip co-developed with Microsoft that puts an RTX 5070-class GPU and the full CUDA software stack inside a thin Windows laptop or compact desktop for the first time.

Technical Specifications

The RTX Spark is an Arm-based chip that packs 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. As a result, Nvidia says the RTX Spark is capable of 1 petaFLOP of AI performance. The debut PC processor is made up of two flagship types of Nvidia chips fused together, plus 128 gigabytes of unified memory. It pairs one of Nvidia's Blackwell graphics processing units with a new Arm-based custom Grace central processing unit.

Market Impact and Competition

Nvidia has emerged as the world's most valuable company by dominating the market for artificial intelligence chips in the data center. Now the company is expanding its prowess to chips that will serve as the main processor for personal computers, entering an arena that's long been ruled by Intel, Advanced Micro Devices, Qualcomm and Apple. The RTX Spark represents a potentially major shake-up for the PC industry, which is already experiencing significant shifts driven by the AI boom. Arm-based processors like Nvidia's are gaining ground over the traditional x86 processors championed by Intel and AMD, while the overall market for CPUs is exploding into what Huang says will be a $200 billion industry.

Availability and OEM Partners

The RTX Spark superchip debuts in the fall on a fresh line of Windows PCs from Microsoft, Dell, HP, ASUS, Lenovo and MSI. Nvidia says 14mm of thickness, 3 pounds of weight, and availability in 14-inch and 16-inch sizes, with OLED displays and precision-machined aluminum chassis. While RTX Spark will eventually expand to different price points, Nvidia said it's currently targeted toward creators, AI developers and gamers, "looking for very thin and light laptops, slim laptops, portable laptops, or compact desktops."
