2nm chips Honey, IBM has shrunk the chips (again)

摘要

The smallest microchips ever made, created by IBM in its test labs in Albany, New York state. It announced the breakthrough in May, predicting that it will lead to a boost in computing power while using less energy. The 'nm' stands for nanometre, which is a billionth (0.000000001) of a metre, so the chips (or semiconductors) are almost unfathomably small. They're narrower than a single strand of human DNA. However, the name '2nm' itself doesn't specifically refer to the size of the chip. Instead, it's a marketing term used to describe the power and performance of chips, with smaller being better.
