I think the real reason people are sticking with intel is the support and supplychain. Intel have a reasonable two-way communications system with big customers, they also write their own firmware still, instead of slinging it out to contractors (although AMD are apparently changing that) crucially they are able to supply 500k procs at a fixed price in a fixed deadline. AMD are yet to be able to do that for big non-consumer suppliers(is what my hardware contacts tell me that is. )
