The 12-inch MacBook with Retina display is sexy to behold, but its specs may leave more to be desired.

Thanks to some new benchmarks, we have a clearer picture of what to expect from the new MacBook’s processor. And it’s basically as powerful as a 2011 MacBook Air.

My Cult of Mac colleague Buster Hein recently wrote that the new impossibly-thin, gorgeously Retina displayed MacBook “isn’t for you, it’s for the future” — meaning that it’s there to show us where the MacBook will go in the next few years, rather than being 2015’s “must own” notebook.

That may well be true, but according to supply chain sources, it’s still likely to make up a pretty sizeable slice of Apple’s overall Mac sales in the year to come.

Citing panel supply chains, the 12-inch beauty is expected to represent between 15-20 percent of Apple’s overall MacBook shipments this year: making it the single largest source of growth in the MacBook series throughout 2015 in the process.

One of the less frequent—yet just as persistent—rumors in the Apple universe is the notion of 12-inch MacBook Air with a completely redesigned exterior.

Much like how Apple has gone back to the rounded design of the original iPhone with the 6 and 6 Plus, reports have claimed that this new MacBook will feature a fanless, clamshell-like design in the three main iPhone colors: Space Grey, Silver, and Gold. Now more details about the unannounced laptop have emerged.
