It was previously assumed this was Coffee Lake but new information indicates this chip may actually be a Kaby Lake Refresh. German tech site Golem claims Coffee Lake is slated for February 2018, and that we're going to get a Kaby Lake Refresh in September 2017.
The site explains Intel showed confidential roadmaps to its partners at Computex. The latest roadmaps show the chip giant is planning to roll out the Kaby Lake Refreh close to the IFA show in September. This lineup will include 15W TDP quad-core chips for ultrabooks, a class that had previously seen only dual-core models.
Coffee Lake on the other hand won't arrive until February 2018. This lineup will make six-core processors mainstream.
