I think the problem AMD has is that they just don't have enough engineers and can't hire more because nvidia (an to a lesser extent Apple, AWS, Google and Microsoft) just gobbles up all people who have any experience with this sort of thing.
A long time ago AMD decided to 100% focus on budget consumer graphics (including consoles), that decision was the right decision at the time. However being in low-margin business it seems they don't have the people (or the budget to last-minute hire) to pump out the R&D for a generic neural network platform without moving people away from their consumer graphics division.
