This is definitely a concern, and more so for the shareholder than the consumer/customer.
But this is precisely what "fading to irrelevance" looks like. We've already witnessed it so many times in x86, most recently with Via (which is irrelevant in all but name only these days).
Sure they are holding on, but the product pipeline is resource starved for lack of corporate revenues which is a vicious self-perpetuating cycle. Once you fall off that wagon, rarely do you succeed in getting back on.
The war in the PC CPU market is more or less over -- Intel won, and frankly, as interesting as AMD's new K12/Zen sounds, I just don't know how they'll really be able to outgun Intel's larger resources and stronger base to build off of.
AMD now needs to fight a different battle, one against more evenly-sized and resourced peers.
If AMD were to go all-in in trying to become another Freescale/NetLogic, I could see that working. If they were to try to become another NVIDIA I could see that working too.
The problem here is that they're trying to be Intel, Freescale/NetLogic, and NVIDIA. They don't really have the resources to be competitive against all three at the same time, and I believe AMD's management understands this. But they can't signal it until the "transition" is effectively complete. They need to string investors along into thinking that all of these opportunities are open to them in light of the current weak operating results.
But, I think, if AMD can get its revenue/profit situation under control through successes in a few areas, it can more easily justify to investors a "leaner" strategy.
