Really, I don't know why AMD sold Global Foundries. Had they kept an iron grip on it, they could had them perfect the 32nm process a bit better then origionally. Also, a die shrink can only carry so far in performance. And I personally wouldn't mind the BD to be edited onto a 40nm die for better yields. 32nm is quite small. And I think intel may run into the problem of electrons suddenly jumping around the transistors into places they are not supposed to be, because they CAN freaking do that surprisingly.
But who knows. TMCS may have perfected their development. Also, I highly doubt that Apple will ever buy AMD. Apple so far has been using Intel to drive their machines, and using AMD for their desktops and laptops means a complete recode of the OS. AS WELL the fact that if they were used for just notebooks, then it would be a waste.
I would not say that AMD is behind just yet! All companies have their bad moments, but they will prevail sooner or later. Even if they do fail the CPU market, they do have the GPUs. Their GPUs are becoming more popular as gamers realize that most of the stuff on an Nvidia card does not really give you any special luxuries as people don't tend to use them. With OpenCL and the amount of cores it has, you would see some pretty god like performance.
