Intel's Coffee Lake S CPUs are based on the company's most advanced and refined 14nm++ process node to date.

It looks like things haven’t gone any better for Intel and their 14nm supply as the most recent report by DigiTimes states that the company would be hit by a major shortage during Q2 2019. Intel’s 14nm supply production has been constrained for a while since all of their major product lines utilize the process node and while Intel had ramped up additional supply in Q3 of 2018, it looks like those efforts were in vain.
