Well here's the golem's 'stats', since we're approaching a direct clash.
It doesn't have any durability beyond its components, most of which are metal appliances and machinery. Its strength is enough to pick up and effortlessly carry around adult human with one 'arm', and its speed is only slightly above the human average, though it's not limited by human physiology and thus moves in ways a normal person wouldn't be flexible enough to. If you bat a part of its body far enough away from the rest, it'll go flying and be irretrievable.
As for the 'core orb', that's something you'll have to guess.
