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 AI workloads. Everything ran on Microsoft Surface Laptops, and Microsoft was also present—a clear signal that Redmond is fully committed to making Windows on Arm succeed this time around. 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 AI compute. A lower-end N1 variant with 5,120 CUDA cores is also planned. RTX Spark is not strictly a laptop platform either—NVIDIA also showed compact desktop mini PCs and the DGX Spark, targeting creators and developers who want the same silicon in a stationary form factor. And, looking at that power envelope, I wouldn't be surprised if N1X (or a variant) eventually ends up in a handheld gaming console—it just makes a lot of sense. A chip like this could also compete with semi-custom AMD chips for the next Xbox or PlayStation.
