Obviously Apply believes this to be a major upgrade in Pro Technology. I don't see why everyone is arguing over this first benchmark test. Until these are released, I wouldn't put much faith in the first benchmarks.
unfortunately, so far, most of the previous benchmarks (ie rMBP, etc) that leaked prior to release were spot-on in performance. granted they are using OS 10.9 (still don't understand why people use "OS X 10.x") and there may be bugs with the OS, i'd think performance won't be much further than what was posted.
