twice the pixels/second in half the time, that's theoretically 4x the performance with only twice as many cores, using same or less thermal envolope, and at possibly less speeds, if what the inq says is true (inq says 65w and not the highest clock to be released)

if that's how the setup ran (4 quads new arc vs. 4 dual old arch), then it sounds good to me
