Intel could have pushed opencl to compete with cuda. But they botched it and I believe it was on purpose. There was just one person working on beignet for so long.

They could not let go of their x86 compatibility and “ecosystem” as a talking point and wanted to kill any advancement in heterogeneous computing. They shot themselves in the foot.

I don’t blame amd for not trying hard enough. Things might be good for them now but back when opencl could have used some investment they were busy putting fires.

So yeah. Screw intel and screw apple for their neglect of opencl. And screw them if they say don’t use cuda because it’s not open source.
