Ask HN: Why hasn’t AMD made a viable CUDA alternative?

I appreciate developing ROCm into something competitive with CUDA would require a lot of work, both internally within AMD and with external contributions to the relevant open source libraries.

However the amount of resources at stake is incredible. The delta between NVIDIA's value and AMD's is bigger than the annual GDP of Spain. Even if they needed to hire a few thousand engineers at a few million in comp each, it'd still be a good investment.

The idea that CUDA is the main reason behind Nvidia dominance seems strange to me. If most of the money is coming from Facebook and Microsoft they have their own teams writing code at a lower level than CUDA anyway. Even deepseek was writing stuff lower than that.

What is lower than CUDA? Compute shaders?

PTX assembly. Deepseek used some of it to do a little bit of work that CUDA didn't have APIs for.

Sadly platform specific
