RAM Usage on new M1X MacBook Pro

Is anyone else experiencing extremely high RAM usage on the new M1X chip MacBook Pro that was released a few weeks ago? It seems unusually high that I’m using up almost 20 GB of RAM (200MB - 1 GB per tab) whereas on my 2019 MacBook Pro I opened up the same tabs (and it used up around 6 GB – 100-300 MB per same tab). Is there a reason that the same tab would take so much more RAM usage? And I’m guessing from an overall RAM usage that my 2019 MBP is fully using up the 8GB RAM and then storing the rest of stuff in slower SSD memory?
