"nanostack 3D transistor architecture vertically layers/ staggers components... packs nearly 100 billion transistors onto fingernail-sized silicon, roughly doubling 2-nm node density... up to a 50 percent boost in computing performance or a 70 percent reduction in energy consumption... while the technology is currently an experimental research platform, IBM expects to see a viable path toward commercial mass production within the next five years"
