The power/performance envelope is about the same for both processors (Haswell version of the Xeon (E3-1230v3) and i3-4130T) . So you are trading performance for power in a full load scenario, the idle power usage is going to be similar. Geekbench scores, price and full load power usage for the i3 is about 1/2 of the Xeon, go figure.
