Nvidia RTX Spark: Arm CPU, RTX GPU, and Unified Memory for Windows PCs

Nvidia has announced the RTX Spark, an Arm-based chip designed for Windows PCs, blending a 20-core Grace CPU (co-developed with MediaTek) with up to 6,144 Blackwell-based GPU cores and support for up to 128GB of unified LPDDR5x memory.

Partners including Asus, Dell, HP, Lenovo, Microsoft, MSI, Acer, and Gigabyte will launch slim laptops and compact desktops powered by RTX Spark this fall. Pricing remains unannounced.

This foray into Arm-based Windows PCs builds on years of progress in the Arm Windows ecosystem. Microsoft's Prism code translation layer has matured, and many major apps now run natively on Arm.

Gaming-a historical weak spot for Arm Windows-may see improvement. Nvidia and Microsoft are working with Riot Games (League of Legends, Valorant), Krafton (PUBG), and anti-cheat developers Easy Anti-Cheat, BattlEye, and Denuvo to ensure compatibility. The unified memory architecture also promises enhanced AI capabilities.
