IBM unveils 0.7nm chip technology for AI workloads (opens in new tab)

IBM unveiled a research-stage semiconductor technology on June 25 that it calls the world’s first sub-1 nanometer chip technology, built around a 0.7nm, or 7 angstrom, transistor architecture called NanoStack. The company said the design can pack nearly 100 billion transistors onto a fingernail-sized chip, nearly twice the density of IBM’s 2nm technology announced in 2021. IBM said published technical results project up to 50% higher performance or 70% greater energy efficiency than its 2nm n...
