ZDNET's key takeaways
- IBM's sub-1-nanometer NanoStack architecture holds almost 100 billion transistors on a chip.
- These chips are cheaper to run and more powerful than previous generations.
- NanoStack technology will be great for deploying AI workloads.
TSMC, Intel, and Samsung have all been pushing to produce low‑single‑nanometer chips in the next two years, while planning to produce sub-nanometer chips sometime by decade's end. That race may be over, however, even before it began. IBM unveiled what it says is the world's first sub-1-nanometer chip technology based on a new 3D NanoStack transistor architecture at the 0.7 nm — or 7 angstrom — node.
The research device, introduced ahead of VLSI 2026, is designed to pack nearly 100 billion transistors on a fingernail‑size die, roughly doubling the density of IBM's earlier 2-nm test chip, first shown in 2021. Today, the...
