Re: In other words
Intel doesn't use 10nm for memory because it's not working, which is the same reason they are still using 14nm++ for CPU's.
In an alternative universe where Intel had a working 10nm process for CPU's, they would be utilising the previous gen for other products.
GF never had the money to invest in next gen - while Samsung doesn't have the high performance process knowledge, the challenge is from TSMC/Intel needing to re-coup the cost of their investments by moving into other areas.
