I wonder what the purpose is behind creating a whole new API? Why not just focus on getting Vulkan compute on AMD GPUs to have the data throughput of CUDA?

I don’t know answer to your question, but I recalled something relevant. Some time ago, Microsoft had a tech which compiled almost normal looking C++ into Direct3D 11 compute shaders: https://learn.microsoft.com/en-us/cpp/parallel/amp/cpp-amp-o... The compute kernels are integrated into CPU-running C++ in the similar fashion CUDA does.

As you see, the technology deprecated in Visual Studio 2022. I don’t know why but I would guess people just didn’t care. Maybe because it only run on Windows.

Yes I found CPP AMP really interesting, but since it only ran on Windows..never used it for anything.

		It’s unfortunate they have deprecated it. We how have DXVK which implements D3D11, including compute shaders, for any platform which supports Vulkan. Making that (or a conceptually similar) thing work across platforms is no longer prohibitively expensive. I believe that approach, i.e. the compute shaders, is the correct thing to do because modern videogames use them a lot, the runtime support is stable and performant now. No need for special HPC-only drivers or runtime components.
