Samsung beats TSMC to the 3nm process finishing line

The semiconductor arm of Korean tech giant Samsung is the first to start manufacturing chips using the 3nm process node.
The measurement originally referred to some dimension of each individual transistor but it seems to mainly be a marketing, rather than technological, term these days. What it does signify is that the basic component of a chip has been made an order of magnitude smaller, which has implications for power efficiency, performance and overall chip size.
