It's rather poorly explained / understood outside of kernel circles;
here's the documentation on all of the suspend states:
https://www.kernel.org/doc/Documentation/power/states.txt

So "Freeze" means "Suspend to Idle", which is the only power saving state
available that does not require hardware cooperation.  It will give you
the absolute lowest amount of power saving available, and in most cases
won't even be worth the trouble of having to reconnect network services,
etc. when you bring the machine back out of Freeze.
