AMD is fine. Its processors are competitive (often superior) and it's gaining marketshare. Intel has been in trouble for some time due to its own failure to downscale, a failure which has little to do with x86. They'd be losing to someone else if Apple/AMD hadn't been there. Intel still has some time to recover: it has plenty of money, and Apple/AMD are unable right now to take full advantage of their position. Apple/AMD rely on a supplier (TSMC) which does not have the capacity the supply all or even most of the processor demand, so Intel gets quite a bit of marketshare almost by default.
