I enjoyed huge success with my last home-made computer.
2011-pin Intel processor, four 128-bit memory channels.
Now I'm going for Core i9 X299 and LGA 2066 pins.
More pins are better.

It's all down to the division of labour in pin production. Adam Smith's
law posits that the number of pins doubles about every two years.

I have a good picture demonstrating that. Somewhere!

It is time to rethink microprocessor architecture. Put several
gigabytes of memory on the processor chip. Call it "cache", if you do
not want call it main memory. Alternatively stack RAM chips upon each
other on to the same chip carrier as the core to minimize distances
and hence propagation delays.

If each pin has a few pF stray capacitance and the pins are operated
at 100+ MHz, a huge amount power is lost just charging and discharging
the pin stray capacitances.

No. The number of transistor elements. The number of pins does not
nor did not follow that rule. It jumped in spurts. Chip packages did
not always use all of the pins of a given form factor either.

Support chips (chipsets) also weigh in to this. Math-COs used to be
a separate chip and are now fully integrated, as are everal other
previously external segments of what makes up a computing platform.

LGA 4189 is Intel's Ice Lake Xeon for those playing along at home.

I hadn't found that one yet. AMD's sockets SP3 and TR4 for the Epyc and
Threadripper are 4094 pins. There are a number of FPGA's at around 3000
pins, and Power9 processors have 3899 pins. I'd expect the Power10 to
be bigger, and some of the SPARC processors must surely have vast pin
counts.

cool, are you going to use wire wrap?

One is reminded of the Signetics WOM chip datasheet, with its graph of
number of socket insertions v number of pins remaining...

Somewhere out there there's a pic of a Russian chip way way bigger, with bunch after bunch after bunch of wires hanging off it. I just couldn't find it.

Did you lay out and build your own CPU board?

What OS? Bios?

There are plenty of LGA 2066 MOBOs out there.

At this level, homespun would very likely be a major step
backwards.

I'll take what the pros have been designing and familiarizing
themselves with for years over even the most advanced, knowledgeable
engineer doing one on his own. There are way to many places to get
fouled up. Looking at even the best motherboards, one sees squggly
litle traces meant to adjust physical arrival time of a signal.
A design needs a lot of testing and very few get made from the first
layout iteration.
