Contra revenues benefit to firms that are also AMD customers, the biggest one seems to be Asus for instance, that s not a case that they can manage with a clear cut as getting Intel in trial would also get thoses firms in trial and eventual reprisal would be dreadfull for AMD given their financial situation..
That said not that thoses contra revenues really helped, quite the contrary, HP who didnt seem to jump on this band waggon got an average 2014 year while Asus, a big proponent in this matter, just sold 10 millions related items without any money made..
As to battle the ARM camp, well, the outcome is quite surprising, and AMD are 100% right to not go suicidal a la Intel in razzor margin markets :
