With Apple’s Mac lineup beginning to show signs of aging, consumers are no doubt starting to wonder when they can expect updated models to hit the market. Apple’s product update cycles are in large part driven by availability of new processors, so it pays to take a look at Intel’s roadmap to see what might be coming when to give Apple new options for upgrades.
The MacBook Air is currently the older of Apple’s two current notebook lines (setting aside the non-Retina MacBook Pro that has been reduced to a single 13-inch model and hasn’t been updated since June 2012). Apple’s ultrathin notebook currently offers a choice of two low-power 15-watt Haswell chips to help achieve remarkable all-day battery life. Entry-level models include a 1.3 GHz i5-4250U chip, while higher-end models bump up to a 1.7 GHz i7-4650U processor. Both chips include Intel’s “Iris 5000” integrated graphics that offers reasonable everyday performance in a power-efficient design.
According to an Intel roadmap leaked by VR-Zone [Google Translate], a successor to the current low-end chip is set to launch in the third quarter in the form of an i5-4260U Haswell refresh, presumably carrying just a small speed bump compared to the current chip. Another alternative for Apple could be the 1.4 GHz i5-4350U or its just-announced successor 1.5 GHz i5-4360U. The 4350U chip has been available since last year, but Apple elected not to use it in the current MacBook Air. The high-end MacBook Air situation is less clear, as leaked roadmaps have not yet shown a direct successor to the current i7-4650U chip.
