Well that is business when they are behind, they have to do with what they have and when they have the rest of AMD holding them back, they really can't do much about it. They need to focus on what they can do best and focus on that. Internal compittion will help them strive for more in the short term, but getting talent from outside takes much more money and time. These are things RTG doesn't have. Internally they do have capable engineers.
But the main thing here is they need to stop making obvious mistakes, just by doing that it will improve their corporate image and branding regardless if their products aren't as performant as their competition if they are priced right. But by messing up things like the pci-e spec, fury x launch mistakes, all the AMD cpu screw ups, just makes them look like a bunch of buffoons trying to piece things together after the fact. And they aren't buffoons not from an engineering point of view, from a PR and marketing point of view that is where the problems are coming from.
If this was a different situation like if they were in Intel's or nV's position and they make a slip up on a rare occasion, that's ok (relatively), they can recover.....
