IBM’s new sub-1nm chip comes with nearly twice the density of the company’s 2nm chip unveiled in 2021.
- IBM said the new sub-1nm chip addresses a challenge facing the semiconductor industry as conventional chip scaling becomes increasingly difficult at smaller process nodes.
- The company projects the chip could deliver up to 50% more performance or 70% greater energy efficiency than its 2nm technology.
- IBM said it sees a path to bringing its nanostack technology into production at the sub-1 nm node within the next five years.
International Business Machines Corp. (IBM) on Thursday unveiled the world’s first sub-1 nanometer chip technology, packing nearly 100 billion transistors onto a chip that is the size of a fingernail.
IBM’s new sub-1nm chip comes with nearly twice the density of the company’s 2nm chip unveiled in 2021.
IBM shares were up more than 6% in Thursday’s pre-market trade. IBM was among the top trending tickers on Stocktwits at the time of writing.
Why IBM’s New Chip Is A Big Deal
IBM said the new sub-1nm chip addresses a challenge facing the semiconductor industry as conventional chip scaling becomes increasingly difficult at smaller process nodes.
The company said its 0.7nm, or 7-angstrom, technology demonstrates that continued gains in chip performance and efficiency remain possible even as transistor features approach atomic dimensions. “IBM’s latest chip breakthrough marks a landmark moment in computing, pushing technology beyond the nanometer era to the scale of atoms,” said Jay Gambetta, Director of IBM Research.
IBM said it sees a path to bringing its nanostack technology into production at the sub-1 nm node within the next five years.
How IBM Built The World’s First Sub-1nm Chip
At the heart of the breakthrough is IBM's new "nanostack" architecture, which the company described as the industry's first known three-dimensional, nanosheet-based transistor design.
Instead of relying solely on smaller transistors, the architecture vertically stacks and staggers them, allowing more transistors to be packed onto a chip while enabling different material combinations in each layer to optimize performance and power efficiency.
Based on published technical results, the company projects the chip could deliver up to 50% more performance or 70% greater energy efficiency than its 2nm technology, with applications ranging from generative AI and cloud infrastructure to next-generation electronic devices.
