Can anybody explain why CUDA and Rocm are necessary and why OpenCL isn't the solution? (programming.dev)

I've read multiple times that CUDA dominates, mostly because NVIDIA dominates. Rocm is the AMD equivalent, but OpenCL also exists. From my understanding, these are technologies used to program graphics cards - always thought that shaders were used for that.

There is a huge gap in my knowledge and understanding about this, so I'd appreciate somebody laying this out for me. I could ask an LLM and be misguided, but I'd rather not 🤣

I'm pretty sure OpenCL was just a play by Apple to standardize heterogeneous compute across different hardware companies and prevent CUDA from dominating

But then they deprecated it in favor of Metal which is just an Apple-specific thing. Probably because they were going to their own hardware anyway

So the main company pushing OpenCL is no longer pushing it, pretty sure it's dying out at this point
