The nvptx64-nvidia-cuda target is a compilation target for NVIDIA GPUs. When using this target, the final output is PTX. Two version choices shape that output:
a GPU architecture (for example, sm_70, sm_80, …), which determines which GPUs can run the PTX, and
a PTX ISA version, which determines which CUDA driver versions can load (and JIT-compile) the PTX.
In Rust 1.97 (scheduled for release on July 9, 2026), the baseline PTX ISA version and GPU architecture for nvptx64-nvidia-cuda will be increased. These changes affect both the Rust compiler (rustc) and related host tooling, and they make it impossible to generate PTX artifacts compatible with older GPUs and older CUDA drivers.
The new minimum supported versions will be:
