What's the verb to describe: A's growth rate is higher than B?
Like "outnumber" for A is more than B.
I check the dictionary seems that "outgrowth" doesn't fit in this situation.

There are many options: A's growth rate ____ B's growth rate: exceeded, eclipsed, surpassed, dwarfed, transcended, outstripped.....
