Updated 11-Inch and 13-Inch MacBook Airs Reportedly Coming Next Week
Apple last updated the MacBook Air in June 2013, which featured Intel's energy-efficient Haswell processors, faster PCI Express-based storage, and faster 802.11ac Wi-Fi.
If the claims turn out to be true, it is likely that a new MacBook Air at this point in time would feature a small speed bump among few other changes. As outlined by Intel's processor roadmap, Apple could choose to use a number of just-launched processors for an updated entry-level MacBook Air, including the 1.4 GHz i5-4260U, 1.4 GHz i5-4350U, or the 1.5 GHz i5-4360U.
Notably, the 4350U chip has been available since last year, but Apple elected not to use it in the current MacBook Air. It is also unclear as to what processor Apple would integrate into an updated high-end MacBook Air, as leaked roadmaps have still yet to show a direct successor to the current i7-4650U chip.
Multiple reports have also indicated that Apple is working on a brand new 12-inch MacBook Air for later this year. According to KGI Securities analyst Ming-Chi Kuo, the notebook is expected to feature a thinner design than the current MacBook Air, and utilize a fan-less cooling system, buttonless trackpad, and higher resolution Retina display.
While it is unclear how a 12-inch Retina MacBook Air would fit into the current lineup, analyst Daniel Matte argued that the laptop will be exactly 11.88'' in diagonal screen size, allowing Apple to offer a Retina Display (2732 x 1536, twice 1366x768) with the exact same PPI as the iPad Air (264 PPI).
Apple is also expected to update its line of Retina MacBook Pros during the third quarter of 2014 alongside the aforementioned 12-inch Retina MacBook Air.
