A company called "Cerebra" has made the world's largest Microprocessor chip, it contains 850,000 cores and 2.6 Trillion transistors; but it's not going in a laptop anytime soon, it uses 15 KW of power.

They do: 46k mm^2.  That dude would be about the size of a salad plate.


Cool!  It would need to be that size to be cool.


I don’t know how it is done in the new days, but in the olden days, all the calculation was done at the core, then all the I/O stuff had to be serially amplified up to the periphery to interface with 5 vdc and the giant meat beasts who supply the power, out in the great unknown, from unfathomable distances, hundreds of meters away.


Most of the power of a chip back then was in I/O.


I was wondering if there was a way to do massively parallel operations with a bunch of cores handing results to each other and not ramping the signal back up to our scale until the endgame.
