Intel's new processor in a word, it would be thin or to perfectly say very thin
The Core M, based on the chipmaker's new Broadwell silicon, debuted on its own Llama Mountain design at the Computex conference in Taipei last week. Llama Mountain is an impossibly thin (may even thinner than the iPad Air) hybrid that bodes well for upcoming two-in-ones running Windows 8.1
Not sure about the Intel marketing the Llama devices but an example in ASUS has only 0.29-inches (7.3mm) thick. It's a Windows 8.1 design that Intel and Asus collaborated on, according to a source familiar with the product. The Chi comes with the same 12.5-inch 2,560x1,440-pixel resolution display as Llama Mountain.
It comes with Intel's new Broadwell chip design. the circuits are smaller and cooler as its the company's most advanced manufacturing process of 14 nanometers, may be even chip M doesn’t need a fan also.
