AMD have a couple of major issues; They don't own a fab anymore, so while intel can decrease their nm size, AMD has to reply on other fabs and what they are tooled for. Intel is heading for 14nm while AMD is currently, and from what global foundries have said, stuck at 28nm for the time being. That means less transistors. Of course, the 28nm (even the 32nm of piledriver..) isn't really mature, and I have no doubt it can be improved and matured for much better performance, it still cannot really beat chips on 14nm that have a world of advantages on how many transistors can be placed on the chip.
Money. While AMD is once again heading back into the black from debt, their revenue base doesn't even approach the amount of money intel spends on R&D alone...think about that for a few seconds. Really, it is a miracle that AMD held the top spot for a few years at all, and is even somewhat competitive with intel now. By all rights, intel should be even further in front with the money they make.
The bulldozer architecture was an attempt to innovate their way past intels lead. It didn't work. Innovating has worked for them before, and really, they don't have any other way of catching intel but by using their resources a lot more wisely than intel. They cannot turn on the money hose and blast their way to the front like intel can.
Of course, there is a catch 22 system now in play. AMD needs money. Since their bulldozer experiment hasn't worked so far, enthusiasts are largely turning to intel. AMD knows this, so they turn to their money making lines; GPUs, APUs, and other lower end chips, etc. On top of this, they didn't build a Steam roller server chip, so they definately won't waste the megabucks on tooling just to make an FX line of steamroller chips that sell in small quantities.
Anyway, that 8350 of yours will still be good enough in gaming for years yet. i wouldn't worry about it if I were you. We will see what AMD can bring to the table in the future, but unless they make money, there won't be an AMD to make anything...and believe me, I don't want that to happen...nobody here will want that to happen. i can just see the $500+ i3 from intel....
