High SA laptop scientist on IBM’s chip breakthrough
Prof Francesco Petruccione IBM this week claimed the first sub-nanometre chip, a era it calls the 0.7nm, or 7-angstrom, node. It says the design packs almost 100 billion transistors onto a fingernail-sized floor, about twice the density of its 2nm chip from 2021, with as much as 50% extra efficiency or 70% higher power effectivity….
