According to the log_summary (which you NEED to send in full if we are to
understand anything), the memory usage is largely the same.
There are more matrices, which leads me to believe that GAMG is not
coarsening as quickly. You might consider a non-zero threshold for
it.
The best way to understand what is happening is to run Massif (from
valgrind) on both.
