Kind of the opposite actually. PTX is in essence nvidia specific assembly. Just like how arm or x86_64 assembly are tied to arm and x86_64.
At least with cuda there are efforts like zluda. Cuda is more like objective-c was on the mac. Basicly tied to platform but at least you could write a compiler for another target in theory.
IIRC Zluda does support compiling PTX. My understanding is that this is part of why Intel and AMD eventually didn't want to support it - it's not a great idea to tie yourself to someone else's architecture you have no control or license to.
OTOH, CUDA itself is just a set of APIs and their implementations on NVIDIA GPUs. Other companies can re-implement them. AMD has already done this with HIP.
Ah, I hoped it was cross platform, more like Opencl. Thinking about it, a lower level language would be more platform specific.
