IBM unveils sub-1-nanometer chip architecture that stacks 100
billion transistors onto a fingernail-sized processor

. . .

    Pretty impressive ... and stacking two (three?) layers
    really packs a lot in.

    NOT sure how they deal with the HEAT in the stacked
    design.

    100 billion ... how many in the i4004 ?
