Helping to create a viable ARM server market, if that's possible, is an entirely different and potentially much more rewarding thing than making another bet on a perennial long term loser like AMD (sometime before their most recent peak and decline in the x86_64 domain it was noted that they'd never made their shareholders money if they'd bought and held their stock). Intel is kind of the opposite, they're usually very good (and have almost always been a fab line powerhouse (the major exception would be when they exited the DRAM market)), and only occasionally get really wedged. At this point, I wouldn't expect support for AMD to do more than drop Intel's prices a bit, and maybe not at all given how the server, desktop, laptop and mobile markets are moving. It's also an indirect bet on TSMC vs. GlobalFoundries and/or Samsung.
