I think it will bite them in the ass the same way glide did for 3dfx. Vulcan/SpirV may end up as the openGL of heterogeneous computing. Nvidia has the momentum

I think it will bite them in the ass the same way glide did for 3dfx. Vulcan/SpirV may end up as the openGL of heterogeneous computing. Nvidia has the momentum at the moment with a focus on GPGPU, but if we can get an open API that leads in performance across vendors for both CPU and GPU we'll see that competition again. We just have to hope that nvidia doesn't nerf their implementation like they did with openCL.

It is not only performance. NVidia was clever to see that no one wants to code GPGPU code in C, rather leverage their C++ source code and the Fortran libraries with decades of investment. So CUDA has been language agnostic from the first day. Khronos has realized their error by creating SPIR, but it might be too late already. Also the debugging experience for CUDA has always been quite good.
