Intel is once again experiencing trouble with its next-generation, 10-nanometer processors – codenamed Cannon Lake – pushing their release back to late 2018, Digitimes reports.

This is far from the first time that Intel’s Cannon Lake processors have reportedly run into setbacks, first set to release in 2017. According to Digitimes’s supply chain sources, which appear to have been accurate up to now regarding Intel's movements, this would be the third time that the Cannon Lake will have been pushed back.
