Even if you include the time when AMD got its act together with the Athlon, and the high margins, it has destroyed an enormous amount of shareholder value over the years. It may have a lucky streak here and there, but in the long run, the house always wins, and on x86 turf, the house is Intel. On ARM turf, there is no house. AMD would be competing with companies of comparable size and capabilities, instead of being beaten to a bloody pulp by the 800lb gorilla. ARM is the future of the consumer space, x86 is going to be a CPU for workstations and servers, before eventually getting out-commoditized from below by ARM, just like x86 out-commoditized RISC workstation and server CPUs.
