Only if the only thing one cares about is CUDA C++, and not CUDA C, CUDA C++, CUDA Fortran, CUDA Anything PTX, plus libraries, IDE integration, GPU graphical debugging.
CUDA C works fine with HIP not sure what you're referring to. As for the other pieces, GPU graphical debugging isn't relevant for CUDA and I don't know what IDE integration is special / relevant for CUDA but AMD does have a ROCm debugger which I would imagine would be sufficient for simultaneous debugging of CPU & GPU. You won't get developer tools like nsight systems but I'm pretty sure AMD has equivalent tooling.
As for Fortran, that doesn't come up much in modern AI stuff. I haven't observed PTX / GCN assembly within AI codebases but maybe you have extra insight there.
