What is decidedly different, however, is the integrated HD 5000 graphics from Intel, a step above the HD 4000 in the previous Air. Any of the past few generations is more than powerful enough for mainstream users. As a longtime MacBook Air user, in everyday use - Web surfing, social media, HD video playback - the 2013 MacBook Air didn't feel any different than the previous version. Year-over-year application performance doesn't show any real improvement, and the new Air actually ran some tests a hair slower. The actual difference in our test results between the 20 models was minor. The MacBook Air keeps the same external look as the previous couple of generations, a look that still rivals the newest ultrabooks, although some new systems, such as Sony's Vaio Pro line, are getting thinner and lighter without sacrificing much in the way of productivity.
