IBM Debuts Sub-1 Nanometer Chip Technology
What's happening: IBM has announced what it calls the world's first sub-1 nanometer chip technology, unveiled today from its research division. The technology uses a new gate-all-around transistor architecture designed to extend semiconductor scaling beyond current physical limits while delivering higher performance at lower power consumption.
If manufacturable at scale, sub-1nm process nodes would reset competitive dynamics across the chip industry — directly affecting AI accelerator performance, data center energy budgets, and the supply positions of TSMC, Intel, and Samsung, all of whom are currently competing at 2nm nodes. What to watch: IBM's disclosure of a manufacturing partner or licensing agreement for the sub-1nm process, which would determine whether this remains a research milestone or enters a production roadmap.
