Why This Matters
Nvidia's release of the first Windows on Arm GeForce driver with RTX Spark support marks a significant step towards expanding GPU capabilities and compatibility for ARM-based systems. This development enables developers to optimize and test their applications on Windows on Arm, paving the way for broader adoption of high-performance GPU computing on mobile and lightweight devices. As the industry moves towards more versatile hardware, these updates are crucial for fostering innovation and ensuring consumers benefit from enhanced performance and software support.
Key Takeaways
- Developers can start porting applications to Windows on Arm using existing systems.
- Performance issues like reduced CUDA transfer speeds are acknowledged, with workarounds available.
- Certain features like Nsight Copilot are temporarily unavailable in this preview.
Developers can begin preparing their applications for Windows on Arm and RTX Spark today. You do not need RTX Spark hardware to get started-an existing Windows on Arm development system can be used to port your application, identify incompatible dependencies, and bring up an initial Arm64 build.
Recommended Steps
Review your application and third-party dependencies for Arm64 support.
Choose an Arm64 or Arm64EC porting strategy appropriate for your application.
Build and test your application on Windows on Arm.
Validate the NVIDIA and CUDA software paths used by your application.
Test installation, updates, functionality, and performance.
Validate on RTX Spark when supported hardware and software become available.
Known Issues
Reduced CUDA transfer performance with pageable memory
