IBM's 0.7nm chip puts nearly 100 billion transistors on a fingernail and resets the AI silicon calculus

IBM has unveiled the world's first sub-1 nanometer chip technology at the 0.7nm node, packing nearly 100 billion transistors onto a fingernail-sized chip using a new nanostack transistor architecture. The breakthrough targets AI inference workloads and promises at least a decade of continued scaling, though the gap between IBM's research results and volume production remains the central unanswered question.
