"M-x gud-gdb" is the old way of running GDB under Emacs.  It relies on
a GDB feature, called "annotations", which is deprecated by the GDB
developers, and could be removed from GDB at any moment.

"M-x gdb" with all its features was written to be the main method of
running GDB from Emacs.  We suggest that you use only "M-x gdb",
unless you have a very good reason, like some version of GDB that
doesn't support the mi interface well.

I don't think I understand what you are asking.  Please elaborate.
