CNET's Shara Tibken writes: "Intel -- which provides the chips that power the vast majority of the world's PCs and servers -- first teased the sixth generation of its Core i-series processors a year ago and officially introduced the chip, known by the codename Skylake, in August. The processors act as the brains of devices, and Intel has focused on reducing power consumption and boosting their capabilities.
"Because of Skylake's features, companies will be able to release laptop PCs that are half as thick and half as heavy as those from five years ago, according to Intel, while at the same time enabling double the performance and triple the battery life of computers from 2010. And Intel's also making a push toward 'wire-free' computing, with many Skylake systems supporting wireless charging."
New Skylake-powered PCs are hitting stores this fall.
