Apple has been developing some revamped Mac laptops for several months and years, such as an ultra-slim 12-inch Retina MacBook, and the key to shipping these products is the availability of Intel’s upcoming Broadwell chip. Why? Because the new 14nm Broadwell Core M chip is fanless, small, and according to Intel, the most energy-efficient Intel processor yet. These facts about the processor lineup directly with the rumors of a fanless and light MacBook. Today, Intel has disclosed some new key points about the Core M Broadwell processor:

The combination of the new microarchitecture and manufacturing process will usher in a wave of innovation in new form factors, experiences and systems that are thinner and run silent and cool.

Intel architects and chip designers have achieved greater than two times reduction in the thermal design point when compared to a previous generation of processor while providing similar performance and improved battery life.

The new microarchitecture was optimized to take advantage of the new capabilities of the 14nm manufacturing process.

Intel has delivered the world’s first 14nm technology in volume production. It uses second-generation Tri-gate (FinFET) transistors with industry-leading performance, power, density and cost per transistor.

Intel’s 14nm technology will be used to manufacture a wide range of high-performance to low-power products including servers, personal computing devices and Internet of Things.

The first systems based on the Intel® Core™ M processor will be on shelves for the holiday selling season followed by broader OEM availability in the first half of 2015.

Additional products based on the Broadwell microarchitecture and 14nm process technology will be introduced in the coming months.

Notably, as Intel executives hinted earlier this year, Intel is still on track to ship out chips in time for new products to hit this holiday season, and it seems likely that the new 12-inch MacBook will be one of the first major computer launches with the new processor. Intel says that increased availability for the Broadwell processor will occur in the first half of 2015, so it wouldn’t be a stretch to expect various other new Macs (perhaps MacBook Pros or Airs) with more powerful Broadwell chips to hit the market during that timeframe next year.
