Not really, "7 nm" is just a marketing name, the actual transistors are around 50 nm:

- mattashii 1y agoIt's true that the transistors are on the order of 50nm, but the conduits for getting the electrons to those transistors are presumably a bit smaller than that. Probably not 7nm small, but not the full 50 nm either.
