Nanometer in the chip refers to the process of producing the chip, and 3 nanometer refers to the etching size of the processor.
The 3-nanometer chip is based on Gate-All-Around technology. Samsung says the initial 3-nanometer chip will reduce energy consumption by 45%, improve performance by 23% and reduce area by 16% compared to its 5-nanometer chip. All-surround grid-stage technology can ultimately reduce energy consumption by up to 50%, improve performance by 30% and reduce area by 35%.
