Not sure EETimes attended the same papers I attended. I heard both papers, and spoke with several colleaggue. The consensus was universal: all believed in the Semiconductor Engineering version (link above). The papers were anything but a revival.
I haven't seen good cost estimates but that is actually my primary area of experitise these days. I am currently working with several lithography and materials experts on detailed comparisons of all of the alternatives.
I can say that Intel has detailed plans through 10nm and they are forecasting that their cost per die is going to continue to go down ~30% for each of the 14nm and 10nm nodes. Intel is a little bit unique at the moment in that they are doing a full srink at 14nm where many foundries are maintaing the same BEOL for 14/16nm that they have at 20nm
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
