AMD took the performance crown from Intel by catching them with their pants down, Intel had grown lazy and was riding the wave it had created, but wasn't doing anything innovative. Intel has learned from that mistake, and they won't ever repeat it.
AMD is still in there putting out a good product. I don't know if they will ever retake the performance title from Intel again, but it is good to see that they aren't completely washed out, either.
Honestly, I am glad to see Intel working to put out a good product. Even if that means AMD never regaining what it had, they at least prodded the beast enough to get it to moving again. innovation is good for everyone, especially us performance geeks.
