Intel confirmed this week that it has begun shipments of its 7th generation Core processors, with the code name "Kaby Lake", to PC makers. The first devices with those chips could be released sometime this fall.
Intel CEO Brian Krzanich made the announcement earlier this week about the Kaby Lake processors shipping to OEMs as part of Intel's quarterly conference call with investors (via Anandtech). Those processors will be made under the 14-nanometer process. Krzanich did not offer specifics on which Kaby Lake variants will ship first, but more information on those chips will likely be revealed at the company's IDF conference in mid-August.
While we will almost certainly see some upcoming Windows 10 PCs with Kaby Lake chips inside sometime this fall, recent rumors claim that Microsoft may wait until the fall of 2017 to introduce Intel's latest processors in new Surface Pro and Surface Book products.
