Larger damage dice does not constitute a huge increase in power overall just by 1 step.That is a significant power boost, especially when the race can multiweapon fight and powerful build stacks with enlarge person. Being able to wield one-handed weapons as light weapons and two-handed weapons as one-handed weapons is a pretty huge boon for a TWF fighter, especially one with four arms.
Powerful Build: The physical stature of half-giants lets them function in many ways as if they were one size category larger. Whenever a half-giant is subject to a size modifier or special size modifier for a Combat Maneuver Bonus or Combat Maneuver Defense (such as during grapple checks, bull rush attempts, and trip attempts), the half-giant is treated as one size larger if doing so is advantageous to him. A half-giant is also considered to be one size larger when determining whether a creature's special attacks based on size (such as grab or swallow whole) can affect him. A half-giant can use weapons designed for a creature one size larger without penalty. However, his space and reach remain those of a creature of his actual size. The benefts of this racial trait stack with the effects of powers, abilities, and spells that change the subject's size category.
That is from the Half-Giant obviously but that does not mean he can one hand a Greatsword, it means he can hold a Large Longsword in one hand, a Large Greatsword is still two handed for him.
