Nvidia’s RTX Spark Arm-based laptop chip arrives in six Windows models priced from $2,600 to $7,000

Nvidia’s RTX Spark N1X is an Arm-based system-on-chip designed for Windows laptops and small desktops, positioning itself against offerings from Apple, Intel, AMD, and Qualcomm. The chip integrates up to 20 CPU cores and 6,144 GPU CUDA cores, with unified memory configurations reaching 128GB in flagship models.

Six manufacturers have released RTX Spark-based Windows laptops; reviewers collectively tested four models from Asus, HP, Lenovo, and Microsoft. The tested devices span configurations with 32GB, 64GB, and 128GB of unified memory, priced between $2,599.99 and $6,999.99. A lower-cost variant with an 18-core CPU and 5,120 GPU cores starts at $2,599.99.

Early user reports indicate that Windows on Arm has improved to the point where native and emulated apps are indistinguishable in day-to-day use. Reviewers note compatibility with Adobe’s native Arm builds of Photoshop and Premiere, and stable operation of common productivity tools such as Signal, Discord, Slack, and Evernote via Microsoft’s Prism emulation layer.

Gaming performance varies by title and settings. Medium settings at 1440p with DLSS performance mode generally yield stable 60fps across tested titles. Black Myth: Wukong averaged 70fps at native resolution with these settings, Cyberpunk 2077 averaged 66fps, and Forza Horizon 6 averaged 57fps. High-end gaming at native 4K and maximum settings remains outside the scope of these laptops.

Local AI model inference is feasible on high unified memory configurations. Reviewers highlight the ability to run sizable local models on devices with 64GB and 128GB unified memory, though detailed performance metrics were not provided in the early testing period.
