NVIDIA’s CUDA Toolkit 13.4 adds Windows on Arm support and greater control over shared GPUs.

NVIDIA’s September 9 developer-blog announcement identifies Windows on Arm support as an addition in CUDA Toolkit 13.4. This is a software-platform compatibility update, not an announcement of a new Arm CPU or NVIDIA GPU.

The release also adds greater control over shared GPUs, according to the article title. That is a separate capability from Windows on Arm support, but the supplied excerpt does not describe its interfaces, configuration options, or supported sharing mechanisms.

NVIDIA’s excerpt broadly describes CUDA releases as adding functionality and performance improvements for its GPUs and software ecosystem. It provides no release-specific benchmark, supported-device list, driver requirement, or quantitative performance gain, so none can be assigned to version 13.4 from the supplied material.
