has officially released the 13.4 Toolkit, introducing critical support for Windows-on-Arm for RTX Spark PCs. This update includes significant enhancements to the CUDA compiler, PTX ISA, CUDA C++, and CUDA Tile programming for modern developers.
The toolkit enables early developer access to Vera Rubin CPUs and GPUs, allowing for the preparation of Windows Arm64 applications. It also ensures CUDA can run on existing Windows-on-Arm systems while updating essential runtime APIs and software libraries.
This release is vital for developers targeting NVIDIA RTX Spark platforms, which are scheduled for an October 2026 launch. By providing these tools now, NVIDIA ensures the ecosystem is ready for next-gen hardware. The CUDA 13.4 Toolkit is available now.
