The summary suggests that the "performance should closely match the recently released Intel Core i7-4770K Haswell processor", but nothing in the article, or anything released about this chip so far, supports that. It's all just guesswork until we see some actual benchmarks from the chip.
I don't honestly expect we're going to be seeing performance parity from this chip (although I'd love it to be true). But that hasn't been AMD's selling point for me for a long time. Chances are, we're going to see a chip that breaks the 5.0 GHz barrier, under-performs relative to Intel's top end chip, but costs about half as much. That's been their game for a long time now, and I haven't seen anything that leads me to believe that this chip is changing that.
