Apple is widely expected to launch a smaller, thinner, fanless 12-inch Retina MacBook Air laptop next year, and it may feature a design made possible by Intel’s Core M “Broadwell” processor the chipmaker launched this year. CPU World has listed four brand new Intel Core M processor versions that are even better than the Core M chips Intel already launched, with MacRumors saying these Core M versions are destined for Apple’s upcoming Retina MacBook Air.

FROM EARLIER: Mysterious feature teased for rumored Retina MacBook Air

The publication says that Apple has already tested some of these new Core M chips for the 12-inch MacBook Air. The chips include “a new high-end 5Y71 chip running at 1.2 GHz with a max turbo of 2.9 GHz, two new mid-range chips arriving as 5Y51 and 5Y31, and a new low-end 5Y10c variant.”

All chips offer faster graphics than their predecessors without requiring more power, and graphics frequencies have moved from 100MHz to 300MHz across the board. Frequencies go all the way up to 900MHz for turbo mode in the new chips.

Many reports have said that Apple is working on a redesigned MacBook Air model that will not only pack a high-resolution Retina display, but also a slimmer design since it won’t require a fan for cooling thanks to the use of the low-power Intel Core M processors. Apple is expected to launch the updated MacBook Air at some point in mid-2015.

More details about these Intel Core M chip version that are rumored to be used by the upcoming redesigned Retina MacBook Air are available in the following table.
