3nm is a bullshit marketing name. The minimum spacing between wires on "3nm" process is 24nm, the minimum spacing between gates is 48nm. Impressive enough, considering that the wavelength of the ultraviolet light used to create the circuits is 13nm. The actual density increase vs 5nm is roughy 1.25.
