I got the impression that x86 CPUs are designed to communicate with only 
a fixed number of peers.

For example, a socket 939 Athlon can only be run in a single-chip 
configuration. But a socket 940 Opteron has an extra pin which enables 
it to run in single-chip or dual-chip configuration. (But not 
triple-chip or more.) In later Opteron generations, part of the model 
number tells you what the maximum number of chips you can wire together 
is. I gather Intel Xeon chips use a similar system.

Given that the reviews talk about 1-chip, 2-chip, 4-chip and even 
8-chip, I very much doubt anybody has bothered to design a 96-chip part. 
Who would they sell it to, after all? (And wouldn't it need 96 extra pins??)
