NVIDIA has introduced the RTX Spark, an Arm-based processor codenamed N1X, designed to run all Windows applications seamlessly in collaboration with Microsoft. The processor features up to 128GB of unified memory, native support for AI agents, and is integrated with NVIDIA’s graphics stack. The Surface Laptop Ultra is among the first devices to utilize this processor. Jensen Huang, NVIDIA's CEO, claims the RTX Spark can run 100% of NVIDIA’s software stack and has been meticulously optimized for compatibility with Windows applications. While many popular applications and games now run natively on Windows on Arm, NVIDIA has not yet released performance benchmarks for the RTX Spark. The "Prism" emulator allows Windows apps designed for x86 processors to run on Arm hardware through real-time translation, enhancing performance. Recent updates to Windows 11 have improved support for various x86 extensions, increasing compatibility for applications.
