"Intel was wrong, it seems. HP Inc, the world's second-largest PC maker, has forecast that Chipzilla's CPU shortages won't be over by anytime soon – not until at least the third quarter."
Intel weren't wrong, they were just very economical with the truth. They pumped premium server chips for the revenue and until the market was "oversupplied" and then switched to premium desktop chips and will likely switch back again. All at 14nm naturally, as that process works.
Oh...you wanted low-mid range chips? Just pay a little more and we might make some more. Don't worry, it will all be OK once 10nm is online in Q2^H3^H4 because we'll definitely have everything sorted. Yes...we didn't specify a year....you caught us...
Look how amazing our EUV process is....mind waiting until 2021?
