IBM Unveils Chip Architecture That Doubles Transistor Density, Claims Breakthrough Performance

IBM announced a new chip architecture that integrates nearly 100 billion transistors on a fingernail-sized chip, roughly twice the density of its previous generation. The company calls it the “world’s first sub-1 nanometer chip technology,” though the term refers to a novel nanostack design that delivers the performance gains expected from sub-1nm features without physically shrinking components. IBM says the technology dramatically improves compute performance and energy efficiency for AI data centers, representing a significant leap rather than an incremental step.
