Moore's law (1965) was that number of transistors per single chip doubles every year. The revised law (1975) is that it doubles every two years. You can achieve that by increasing chip area, increasing density. In the near future also stacking transistor on the same chip over each other. Packaging multiple chips into one is not part of the Moore's law. AMD gets better yield by quitting the race and it seems to be real end of Moore's law. Density increase is still going on but it can't keep Moore's law going. Just putting more and more chips in package would be stupid measure for Moore's law. Arbitrary sized circuit board can be packaged in epoxy.

> Moore's law (1965) was that number of transistors per single chip doubles every year. Not exactly. It was on the cheapest chip cut. You can't fix it by trading area for yield, nor by creating more expensive denser processes. Chip manufacturers are currently doing both of those, what is good, obviously, but won't bring the kind of evolution we used to get.

  I assume that the "cheapest chip cut" is also improving over time, if only in the sense of cost per unit of transistor area. That's perhaps the facet of Moore's law that's going to be comparatively easiest to keep going.

    Yes, the cheapest size (in mm2) has been increasing since the beginning. But it has always been a minor gain. Boubling it every few years will stop being useful very quickly.

The point of chiplets is to make effective use of the leading nodes, obviating yield issues for these while resorting to cheaper, coarser nodes for non-critical parts of the whole package. They're not saying that having a multi-chip package by itself is enough, but this is what's enabling them to leverage other improvements. It's not even restricted to Intel, AMD is doing the same thing.
