Also this fanatic focus on the FEOL needs to stop, ~80% of the power consumption, even in an OoO CPU, is in the BEOL.

- mjevans 9y agoCould you elaborate about FEOL and BEOL? Do those correspond to the most base layers of structure creation and modification on a chip and then the larger structured interconnect layers that get added later respectively?
- deepnotderp 9y agoFEOL = Transistors, so all the fuss about FinFETs, GAA-FETs, carbon nanotube FETs, etc. BEOL = Interconnects. You know, the stuff that's RC quadratic and ~80% of the power consumption.
- snaky 9y agoMaybe the future of interconnects is mechanical after all. https://www2.eecs.berkeley.edu/Pubs/TechRpts/2017/EECS-2017-21.html https://www2.eecs.berkeley.edu/Pubs/TechRpts/2017/EECS-2017-...
