The first time Jim Keller spoke at one of the AMD all-hands when I was there, he said something like "they said a few years ago that CPUs have pretty much hit their performance limit, but apparently no one told Intel that." It was pretty much the first time I'd ever heard anyone at AMD admit that the CPU cores performance was lacking, at least at that level.
I think people on enthusiast forums assume that everyone working at a CPU company follow benchmarks and know what the competition is doing, but in reality people are just usually focused on their particular job and don't care too much about the big picture besides whether the bonus pool got funded or not.
So, to have someone high up in leadership come out and say "here's where our competition's performance is, here is where we are aiming to be, this is what we are doing to get there" was pretty huge to me, and was almost enough to convince me to stay. In the end, I got a really nice offer elsewhere and moved on, but I do think that Jim Keller has the CPU cores team pointed in the right direction. Whether they still have the resources needed to execute is another question though (that I don't know the answer to).
