The newest Intel CPU (due out in the fall) leap-frogs AMD in performance. See here.
It has 20 – 40% better frame rates on games than the AMD chips, and outperforms generally across all tests. This is very good news for Intel — AMD has been kicking their butts for a couple of years, especially on games, and Intel has been losing market share.
Of course AMD could surprise by announcing a new chip next week that will take back the crown, but it doesn’t seem likely at this point.
