IBM claims world’s first sub-1 nanometer chip technology
Summary
IBM claims a nanostack-based chip architecture is the world’s first sub-1 nanometer technology, enabling ~100 billion transistors on a chip the size of a fingernail and potential 50% performance or 70% energy efficiency gains. IBM emphasizes that the '0.7-nanometer' node is a naming convention rather than a literal physical size, with commercialization possibly a decade away and partnerships with Rapidus and others to scale production.
