"The good news is that despite rumours of major delays, Intel has confirmed that it is finally shipping the Broadwell chips (at least to its customers, like Apple). This will be good news for anyone awaiting the new Retina MacBook Pro, MacBook Air, iMac and Mac mini.
Broadwell, which uses the 14nm manufacturing process, is said to consume 30% less power than it's predecessor Haswell, which should be good news for battery life on the portable Macs.
In a conference call about Intel's second-quarter results on 15 July, Intel's chief executive Brian Krzanich confirmed Intel’s hardware partners will have Broadwell systems on store shelves in the run up to Christmas."
