Refreshed internals, lower price point possible.
Intel's Skylake Processor Lineup for MacBook Air Unveiled
The 2.3GHz i5-6200U and the 2.4GHz i5-6300U chips are appropriate for the lower-end MacBook Air models, while the 2.5GHz i7-6500U and the 2.6GHz i7-6600U would be used in the higher-end MacBook Air models. All four chips include Intel HD 520 graphics. With Skylake, Intel has opted to simplify its graphics naming scheme, adopting 3-digit numbers instead of 4-digit numbers.
It is not clear when Intel plans to release the Skylake chips appropriate for the MacBook Air, but with full specs now available, it seems launch is imminent, perhaps planned for next week's Intel Developer Forum.
According to the information available, 28-watt chips appropriate for the 13-inch Retina MacBook Pro will not be launching until 2016. Launch dates are equally unclear for the rest of the Skylake lineup, as today's leak only covers chips that would be used in the MacBook Air.
Intel's Skylake processors are expected to offer a 10 to 20 percent boost in CPU performance over Broadwell, plus lower power consumption and improved Intel HD integrated graphics performance. Better energy efficiency will also lead to up to 30 percent longer battery life.
