3.0 Conclusion
Comparing Intel's 10nm process to GF's 7nm process they are more similar than they are different. Since both companies are solving the same difficult physics problems this is in some ways not surprising.
The surprising part in my opinion is that GF at 14nm stumbled so badly they had to license it from Samsung. Now they have an internally developed 7nm process that matches up well with Intel's latest 10nm process.
It is also surprising to me to see how far Intel has fallen from the process lead they had. First with HKMG by several years, first with FinFet by several year, I suppose they are still first to do cobalt interconnect but in terms of process density the foundries have caught them and appear poised to take a substantial lead over the next several years.
With Intel offering foundry processes and GF, Samung and TSMC all offering leading edge processes the industry now has four viable leading edge process options.
