It pretty much looks like AMD really cannot put their money where their mouth is, and can't bring itself to actually do what is necessary to compete with the green team.

As a personal anecdote from ~4/5 years back, we contacted an AMD sales rep (AMD Germany) about a product we were developing, that was absolutely flying on NVIDIA consumer hardware. We wanted to know if there was a possibility to explore how it would run on AMD hardware, with maybe a bit of support. They didn't even bother to reply..
