The real question facing us now, I believe, is how is AMD going to compete with ARM-based silicon? I believe that ARM is on the path to dominance due to perfor

  I think it ultimately boils down to who has the best CPU architecture if you are talking exclusively about performance-per-watt. Right now, it feels like AMD/ARM are going to be very competitive with each other in the mobile segment, but only on paper. They mostly stay in their own separate market arenas. Apple may disrupt this soon. The bigger picture is that x86 is a platform that most of the business world runs on top of right now. ARM is certainly pushing into that arena, but AMD is keeping the x86 offering very attractive. I am of the camp that there is nothing intrinsically wrong with x86, and especially not its recent implementations. It is an old & dirty ISA, but it gets the job done. Every scenario on earth has been thrown at it and it has adapted to suit. Decades of iteration and testing with billions of participants. All AMD needs to do is continue cranking out 100W+ TDP parts that tear through workloads. The current style of ARM devices cannot keep up with power budgets like that. I believe they would have to completely redesign their architecture if they wanted to move from 5-15W up to something like the toasty 225W TDP of the 7742.
