Intel(s intc) announced a few new details about its Core M chip on Monday, which is manufactured using a 14 nanometer process. Intel said the first devices using these chips will be on sale in the United States by the holidays.

Last time we heard about these 14nm chips — based on the Broadwell design — they were in a skinny, fanless tablet meant as an Intel reference design. The Intel Core M is targeted at tablets and other mobile devices, but will also most likely end up in laptops, like certain MacBook(s appl) models. Unlike ARM-based chips, the Core M can run a full version of Windows(s msft) or OS X, but whether Intel can convince mobile hardware makers these chips offer the same advantages in power usage and heat remains to be seen.

The biggest advance these chips represent is that they are manufactured with circuitry measured at 14nm. The current generation of chips…
