Since 2015 Intel has been dragging their knuckles with the new 10nm Cannon Lake CPUs for the past 3 years now and
Specifically, a chip manufactured at an advertised size of 14nm may not actually have any part that scales to that size. Intel’s are closest to their advertised size. So if you normalize the node sizes across manufacturers, Intel is actually still ahead in
Basically, don’t bother comparing chips on their advertised node size, it’s just marketing and mostly meaningless. Intel has an advantage and a disadvantage with being both a chip designer and manufacturer. When AMD Spun off global foundries (their manufacturing arm), they were relatively free to shop for the best chip manufacturer to make their chips.
Right now they are going with TSMC because they are first to 7nm. Intel can’t just abandon their factories and go to a rival that has a smaller node technology. Well, they could, but that would destroy their reputation.
As Intel continues to lean on their 14nm silicon, they anticipate challenges with increased demand and supply, which likely is derivative from their 10nm delay. Intel insists they will work with customers and Fabrications to address these issues.
