I' sorry to give such a generic reply but in terms of the mass market & servers/ business, top performance isn't very important.
In the server market, AMD remain competetive because their CPU's scale well in 2+ socket configurations, are competetively priced & are trusted as being reliable (as are intel of course).
In mass market home systems, they are competetive at the low end which accounts for most sales. Your average user doesn't care if their CPU is 20% faster than the alternative - they appreciate (quite reasonably) features - & saving money on the CPU leaves more money to offer them printers, extra storage space, more software etc (again, quite reasonably, although different to my priorities, or yours).
In short, AMD will probably be back in 1/2/3 years at the high end as ever, but the high end (in our sense of the word) has little to do wiith the business plans, profits, market share & success of these large companies.
