Intel rolled out its fourth generation of Intel Core processors this week (the chips formerly known as Haswell), and vendors have wasted no time getting word out about their plans - Sony, for example, has already introduced new ultrabooks with the new chips inside, though they're not expected to ship quite yet. We won't know for sure what Apple has up its sleeve until next Monday, when Tim Cook takes the stage, but MacBook Airs seem certain for a Haswell refresh, according to Mark Gurman at 9to5Mac.
The new silicon from Intel offers dramatically improved power consumption than its predecessor, which now powers Apple laptops: Intel says up to 50 percent better, with up to three times the standby battery life. Other enhancements Gurman predicts in the new MacBook Airs include faster Wi-Fi supporting the 802.11ac standard, which offers the potential for gigabit transfer speeds; a higher-resolution FaceTime HD camera and improved audio input.
Apple introduced the 15-inch MacBook Pro with Retina Display at last year's WWDC, refreshing the MacBook Air and regular MacBook Pro line at the same time. It's made regular tweaks and enhancements to its portable laptop line since then: the 13-inch MacBook Pro with Retina Display was introduced in October, and Apple faster laptop processors and a price reduction in February 2013.
