IBM's fingernail-sized chip squeezes in ~100 billion transistors
June 26, 2026
IBM's sub-1-nanometer node chip fits close to 100 billion transistors for increased efficiency and performance over the 2-nm process node

IBM has developed the blueprint for producing a processor using sub-1-nanometer (nm) chip technology, outdoing its own efforts to increase efficiency and processing power with 2-nm tech from a few years ago.
The 1-nm figure isn't really an accurate measure of the size of transistors anymore. That part of the name of a process node (or chip manufacturing technique) used to refer to the physical gate length of a transistor.
This brief video below explains how that's changed over the years. The key takeaway is that transistors are now three-dimensional and can't be measured the same way as previous generations. What is a lot more important now is transistor density, or how many chips you can fit on to...
