International Business MachinesIBM announced a sub-1nm chip technology breakthrough with nanostack architecture, boosting performance and energy efficiency.

IBM shares jumped about 5% in premarket trading Thursday after the company announced a sub-1 nanometer chip technology breakthrough. The new chip features a transistor architecture at the 0.7 nanometer node, making it the first chip technology to operate below the 1 nanometer threshold. It utilizes a nanostack architecture, a three-dimensional design that vertically stacks and staggers transistors, packing nearly 100 billion transistors onto a fingernail-sized chip, approximately twice the density of IBM's 2 nm chip unveiled in 2021. The chip is projected to deliver up to 50% more performance or 70% greater energy efficiency compared to IBM's 2 nm node chips, and IBM also presented research showing the nanostack architecture provides 40% scaling in SRAM.
