On average, how many transistors is a transistor connected to in a CPU?
What is the average fan-out of a gate in a CPU?
What is the average fan-in of a gate in a CPU?
(I'm guessing these numbers are much less than the average of 7,000 connections between one average neuron and other neurons in the human brain mentioned in the Contemporary transistors question).
In the Apollo Guidance Computer and the Cray 1, every gate has the same maximum fan-in: max fan-in of 3 in the AGC, max fan-in of 5 in the Cray 1. What is the maximum fan-in of any gate in today's CPUs?
