The tradeoff was not that. The OpenCL SW ecosystem was just not there at all. It's not a coincidence that nobody has a good AI training on OpenCL stack even today. The cross-vendor infrastructure for that doesn't exist.

And NV was far from malicious here, they are who made building this ecosystem possible.

Without NV what would have plausibly happened was not having AI training on GPUs at all, but on bespoke accelerators (which _did_ exist back then) at a totally inaccessible cost to customers. It's hard to understate their role in building this ecosystem.

What exactly is the issue? I use OpenCl without significant issues everyday.

The whole library ecosystem, for example (but far from only) if you want a BLAS. OpenCL only provides much lower level infrastructure bricks.

With CUDA having unmatched performance compared to alternatives too.
