I'm not sure I know how to estimate this, but I'd like to know how many 4004s you could fit on a die the size of the original 4004, if you used today's smallest

  I think the 4004 was a 10um (micrometer) technology and new we have 14nm (nanometer) transistors. So the individual transistors are 1400 times smaller in linear dimensions. So you could plausibly pack 1400*1400 = 1960000 or almost 2 million of those into a same sized die.

    Lets build a 1000 core cpu. And since the bottleneck will be the connections, let's build them as SOCs and bundle them with ram and ethernet.

      Here's 144: http://www.greenarraychips.com/ http://www.greenarraychips.com/. Built to run Forth by the guy that invented Forth using Forth: http://www.colorforth.com/vlsi.html http://www.colorforth.com/vlsi.html.

  Per wikipedia 4004 has 2,300 transistors. A 18-core Xeon Haswell-E5 5.5 billion, so that is about 2.3 million of them on 22nm and 661mm2 of silicon. In that features went from 10 micro meter, to 22 nano meter! A scaling of 10,000 in 40 years. https://en.wikipedia.org/wiki/Transistor_count https://en.wikipedia.org/wiki/Transistor_count
