Intel has enough manpower to wrestle absolutely anything or anyone in sw.
Even if they do how exactly is it even a good idea to lean on OCL/SYCL for a compute stack ?

Why would they subject themselves to the torture of less powerful higher level APIs like OCL/SYCL in comparison to higher performing lower level APIs such as CUDA or HIP ? Intel is already going to be losing some performance on the table in the HPC space because they now have to deal with overhead due to the mismatch between SPIR-V kernels and their native hardware ...

Also by introducing an intermediate representations like SPIR-V, Intel risks making things far harder with potentially dealing SPIR-V compiler bugs ...

If this is their 'vision' for GPU compute then they'll soon figure out just how hard it truly is for industry to adopt standards like AMD has in the past with trying to push OpenCL and that ended up in failure ...

Portability is king now.
End of the story.
