That's probably not what you want to know.
My crystal ball tells me that you probably want to know which
"instruction sets" a.k.a "processor architectures" are supported by the
CPU.  Which could be translated to "which ports of Debian could run on
this machine".

The `dpkg --print-architecture` from the previous question shows you one
of the architectures that the CPU supports, but indeed it may support
others as well.  For that, I don't know of a tool that gives you
a straight answer.  You can try installing various ports of Debian see
which one works and which one doesn't.  But a more "deterministic" way
would be to look at the doc about your CPU and compare that with the
requirements of the various Debian ports.
