Intel Delays Mass Production of 10 nm CPUs to 2019
 

Intel on Thursday announced that it would delay mass production of its 10 nm processors from 2018 to 2019 due to yield issues. The company has claimed to be shipping some of its 10 nm chips in small volumes right now, but due to cost reasons the firm does not intend to initiate their high-volume manufacturing (HVM) at this time. Intel executives also stated that they are confident of their product roadmap and intend to launch Whiskey Lake and Cascade Lake products later this year.
