NVIDIA has released a developer preview of GeForce drivers for its RTX Spark PC platform, confirming the variants of the N1X chip and the SKU separation. In GeForce driver version 616.00, this marks the company's first driver package compiled for the Windows-on-Arm (WoA) platform.

Thanks to Windows Latest, which extracted the installation file and examined the information file, there are two main RTX Spark N1X chip SKUs: one with 6,144 CUDA cores and another with 5,120 CUDA cores. Both are based on the "Blackwell" GPU microarchitecture and are paired with a 20-core Arm CPU and up to 128 GB of LPDDR5X memory.

NVIDIA is working with Microsoft to optimize Windows 11, and developers now have access to optimization techniques needed to port AAA titles and productivity software to the platform. The CUDA toolkit for RTX Spark rolls out as a native Windows-on-Arm software toolkit, with driver version 616.00 part of that toolkit.
