Intel gutting 10nm to make mass production possible?

Intel's 10nm issues significantly altered the chip giant's roadmap. Processors made on this node were supposed to be on the market in 2015, but at the moment it looks like we won't be seeing any mass market products until late 2019.

SemiAccurate's Charlie Demerjian writes Intel is still struggling mightily with its 10nm process and that significant changes were made in effort to be able to get 10nm out of the door in 2019. Basically, the site's anonymous sources claim Intel's 10nm is no longer "10nm" but more like "12nm" because the original 10nm was impossible to fix.

The article contains some interesting snippets about the yields of Intel's 10nm process. The initial yields were reportedly as low as 8-10 percent!

How bad is the current 10nm process? To put it mildly it is unworkable on both technical and financial fronts. Initial yields on Cannon Lake which SemiAccurat first reported as, “awful” were in the 8-10% range. Contrast this with their expected range of 50-60% yields on a new process and you have a pretty dire situation. Since then things have improved but not much, think increments not multiples, and multiples are needed. What exactly is going wrong? According to our sources Intel doesn’t actually know, they know what the problems are, but not why things are going off the rails.
