Looks like it's the same equalizer, however the standalone unit is 9 bands instead of 7. I'd default to the assumption that the internal hardware for it is practically the same, but more compact in the integrated version. Whether there's a big difference in the manufacturing/engineering side of that aspect, that's something you'd have to ask Behringer.
If you have the money to purchase the new mixer with the integrated graphic EQ, go for it. But if you're just looking for a bus/master EQ to send to on your groups or master channel and are fine with your current mixer, you'll obviously save money getting the standalone.
But hey, if you've got the money, then you might as well ditch Behringer altogether and go with a Mackie!
