The 13-Inch MBA Burns the Fastest 2010 MacBook ProBrian Barrett7/21/11 8:19am227EditPromoteGo to permalinkHoly crud. While it's just a benchmark test and those don't accurately reflect yadda yadda yadda YOU GUYS. The 1.7GHz Core i5 13-inch MBA just blew the door off of last year's 2.67GHz Core i7 17-inch MacBook Pro on GeekBench. And did more than twice as well as last year's tricked 13-inch Air. That is bonkers.
