## Summary of NVIDIA RTX Spark Platform Details Revealed by New Driver
NVIDIA has provided an early developer preview for its GeForce drivers intended for the new RTX Spark PC platform. This development confirms details about the available variants and specific product configurations (SKU separation) utilizing the N1X chip.
The key information was extracted from driver version 616.00, marking a significant milestone as it represents the first driver package compiled specifically for the Windows-on-Arm (WoA) computing platform.
Technical Specifications Revealed:
Analysis of the installation files indicates that there are two primary configurations for the RTX Spark N1X chip:
* One version features 6,144 CUDA cores.
* The second version includes 5,120 CUDA cores.
Both chips are built upon the advanced “Blackwell” GPU microarchitecture and are designed to work with a 20-core Arm CPU paired with up to 128 GB of high-speed LPDDR5X memory.
Developer and Software Implications:
NVIDIA is actively partnering with Microsoft to ensure optimal performance for Windows 11 on this new hardware. This collaboration gives developers access to crucial optimization techniques necessary to successfully port and optimize major applications—including AAA games and professional productivity software—to run efficiently on NVIDIA’s latest platform.
Furthermore, the rollout of the native Windows-on-Arm CUDA toolkit includes this version 616.00 driver package, providing essential tools for developers building software for the RTX Spark architecture.
