Intel has set a concrete deadline for when it'll finally have processors built on a 10nm process in the mainstream market: holiday season 2019.

While the company's 14nm manufacturing process is working well, with multiple revisions to improve performance or reduce power consumption, Intel has struggled to develop an effective 10nm process. Originally mass production was planned for as far back as 2015. In April, the company revised that to some time in 2019. The latest announcement is the most specific yet: PC systems with 10nm processors will be in the holiday season, with Xeon parts for servers following soon after. This puts mainstream, mass production still a year away.
