@thomasfuchs 1000x shorter and 1000x narrower : 1,000,000x less 2-dimensional area.
A *million* 3nm transistors would fit in the same wafer area as one of those old 3-micron transistors.

  @thomasfuchs my 20 year old self still can't fathom that a breath of wind could whiff 512GB from the table for the doggo to gulp it without serious side effects

  @thomasfuchs The more I've learned about processor manufacturing, the more I'm convinced it is likely our biggest accomplishment. Such insane precision at SCALE is just incredible. Really dealing with manufacturing at “near” atom level.

  @thomasfuchs an ARM cortex m0 fits into two transistors of the 6502. And that was almost ten years ago.

  @thomasfuchs sorry to tell you, but the modern naming convention of processes is no longer a technical term to do with length, and is only a marketing term. See 3rd paragraph of wiki page: https://en.wikipedia.org/wiki/3_nm_process?wprov=sfla1 . However, it's still several orders of magnitude smaller, so your point isn't undermined much!

    3 nm process
    
    In semiconductor manufacturing, the 3 nm process is the next die shrink after the 5 nanometer MOSFET (metal–oxide–semiconductor field-effect transistor) technology node. South Korean chipmaker Samsung started shipping its 3 nm gate all around (GAA) process, named 3GAA, in mid-2022. On December 29, 2022, Taiwanese chip manufacturer TSMC announced that volume production using its 3 nm semiconductor node termed N3 is under way with good yields. An enhanced 3 nm chip process called N3E may start production in 2023. American manufacturer Intel plans to start 3 nm production in 2023.Samsung's 3 nm process is based on GAAFET (gate-all-around field-effect transistor) technology, a type of multi-gate MOSFET technology, while TSMC's 3 nm process still uses FinFET (fin field-effect transistor) technology, despite TSMC developing GAAFET transistors. Specifically, Samsung plans to use its own variant of GAAFET called MBCFET (multi-bridge channel field-effect transistor). Intel's process dubbed "Intel 3" without the "nm" suffix will use a refined, enhanced and optimized version of FinFET technology compared to its previous process nodes in terms of performance gained per watt, use...

  @thomasfuchs I dont think that 3m *technology node* uses transistor whose dimensions are 3nm. They are still significantly smaller than 3um.

  @thomasfuchs I wire-wrapped two additional banks of eight 4116 chips to give my first machine a full 48kb of RAM. It took a shoebox sized enclosure. Obviously, the density could have been increased somewhat, but …
