IBM unveils new record-breaking chip with 100 billion transistors in less than 1 nanometer footprint — new NanoStack design is like "a 100-storey skyscraper" packed with highly efficient processing power

IBM has unveiled what it describes as the world's first sub-1 nm chip technology, carrying nearly 100 billion transistors on a fingernail-sized surface.

The breakthrough revolves around a new 3D NanoStack architecture that moves transistor scaling into the 0.7 nm or 7 angstrom era.

For context, today's most advanced commercial chips typically sit around the 2nm mark, making this a substantial leap in density.
