IBM introduces the smallest computer chip in the world
IBM Research
IBM announced 0.7 nanometer transistor chips, the smallest in the world, using a new three-dimensional nanostack architecture with innovations in wafer bonding and memory scaling. The chips are 70% more efficient than IBM's previous 2 nanometer chips from 2021, and could theoretically enable AI accelerators to deliver 9,000 TOPS compared to current accelerators' 1,500 TOPS, potentially reducing training time for large language models from three months to two weeks. The nanostack design could support a decade of further chip innovations by stacking transistors vertically rather than only shrinking them horizontally.
Why it matters
It’s the world’s first sub-1nm chip technology, powered by IBM’s new nanostack architecture, paving the way for more powerful chips for years to come.
