There are differences, but they're mostly in the details. We tend towards the AMD version of the architecture because those were the manuals I worked from when writing the majority of the x86 code, but our simulation isn't exact enough that the relatively obscure differences matter. We don't model any particular implementation's microarchitecture.

Can anyone tell me which x86_64 machine is being considered here. I am
new to simulators, so correct me if I am wrong. I think all x86-64
machines like Intel Core 2 and Amd 64 will have different
implementation causing a bit different simulation. And I wanted to
know if there is documentation for the code or an ongoing discussion
for the same(I am interested in x86-64, cause I have only that
machines in our college). I would highly appreciate if you could
direct me to the correct direction.
