this isn't a "pissing contest"? you made a speculative claim in a public forum and i'm challenging your authority to make such a claim. a "pissing contest" would be if i had said i've shipped hundreds of thousands of lines of shader code into prod and thus you clearly have no idea what you're talking about because you haven't (which is also true).

I could post the GitHub URLs of all the shader code I wrote that’s running on countless GPUs right now, but what would it change? I’m still just a random guy on the internet with an opinion that happens to be different from your opinion.

You can simply disagree with me, regardless of my experience (or lack thereof).

> You can simply disagree with me

that's exactly what i did and made an argument for why i think you're wrong. in response you provided exactly zero substantive remarks other than "i've written shaders" and then accused me of pissing.

also FYI it's clear from your profile that you've only worked on graphics (embree, blender, etc) and not compute. so i'll repeat: you're an outsider and you have absolutely no idea what you're talking about.

Outsider to what?

▲

to the domain you presume to have authority to comment on

		What domain do you think I was talking about?

If it helps you at all:

“if you've never debugged a GPU synchronization error or kernel panic due to some GPU firmware bug or fought absolute shit profilers hunting for perf”

I have done all of those things. As part of my full time job, for years.

Now that we’ve put all of that aside, can we stop talking about me and go back to discussing moats? What do you think are top three things that are holding customers back from buying AMD GPUs instead of Nvidia GPUs?

I could be misremembering, but I think Jensen Huang himself once called CUDA or the CUDA ecosystem their moat, and it certainly seems to be accepted narrative in the tech press. They may be wrong there, and you sharing your first hand experience here would be helpful to many of us readers here.

		amd consumer gpus don't support rocm. That is basically the entire reason for Nvidia dominance. All Nvidia cards support cuda even the crappy ones
