If you’re expecting to buy laptops with Intel’s next-generation Core chips code-named Cannonlake chips by the end of this year, you may be disappointed.

There’s a chance that shipments of Cannonlake — Intel’s first on the 10-nanometer production process — may slip into next year.

Intel previously said Cannonlake would ship by year end, but that’s now uncertain.

Whether Cannonlake shipments will happen before or after Christmas is hard to predict, Venkata Renduchintala, president of Intel’s PC, IoT, and chip design businesses, said earlier this week at an Intel manufacturing event.
