Using Gungnir is definitely a sign of using something outside his "natural" power; Gungnir is simply a focus though...it doesnt actually amp Odin, but it does allow him to focus his energies more tightly.
As pertains Odins Giant Size, in that form, Odin is far stronger than normal...
He could have assumed that form and completely overwhelmed Thanos physically...
