There's a lot of great stuff at SemiAccurate throughout the years that details what went wrong at Intel and why. Unfortunately, you have to pay for it because Charlie has a practical stranglehold on semiconductor inside information. And Charlie is a bit of a polarizing figure. He's gotten some things hilariously wrong, but he's also been dead on the money for a lot of issues, and his documentation of what's happening / happened at Intel is pretty much crystal clear. You could probably browse through all the 10nm articles there and get a good idea of what happened without purchasing a subscription, if you have a decent knowledge of the semiconductor industry. EDIT: If you read though these articles, even the parts that are available to non-registered users, a pretty clear picture starts to emerge - https://www.semiaccurate.com/tag/10nm/ https://www.semiaccurate.com/tag/10nm/
