  • Disclaimer: not an expert, this is just how I understand it after some googling:

    There isn’t a single standard for 3nm, despite the seemingly obvious size-related connotations. It’s more of a marketing term used by chip manufacturers to refer to their version of the next generation of chip-making processes they each have to create something smaller than the previous revision.

    Any time you shrink a processor you’re using less materials, which means it’s cheaper and allows more room for other things.

    Less materials also means less resistance, so a smaller chip is inherently either more power efficient, faster, or a little of both (depending on the chip and the design the manufacturer decides to go with).
