At Computex 2026 in Taipei, NVIDIA invited the press to a hands-on walkthrough of the RTX Spark platform, spread across multiple rooms covering gaming, creator, and Artificial Intelligence workloads. The demonstrations ran on Microsoft Surface Laptops, with Microsoft also present, underscoring a renewed push to make Windows on Arm more competitive. Microsoft revealed that it has made several kernel-level optimizations to Windows 11 specifically for RTX Spark, changes that notably were never made for Qualcomm’s Snapdragon platforms.
At the heart of RTX Spark is the NVIDIA N1X chip, which pairs a 20-core NVIDIA Grace Arm-based CPU with a Blackwell RTX GPU packing 6,144 CUDA cores and 5th Generation Tensor Cores with FP4 math precision, all connected via NVLink-C2C. The chip supports up to 128 GB of LPDDR5X unified memory in a 45-80 W power envelope (H-segment), and NVIDIA claims up to 1 petaFLOP/s of Artificial Intelligence compute. A lower-end N1 variant with 5,120 CUDA cores is also planned, positioning RTX Spark as a broader product family rather than a single configuration.
RTX Spark is not strictly a laptop platform either, as NVIDIA also showed compact desktop mini PCs and the DGX Spark for creators and developers who want the same silicon in a stationary form factor. The 45-80 W power envelope also points to possible future use in handheld gaming hardware, where an N1X chip or variant could make sense. The same class of chip could also compete with semi-custom AMD chips for the next Xbox or PlayStation, extending NVIDIA’s ambitions beyond notebooks and compact creator systems.
