Overall Performance And Efficiency

Everything calculated together shows a little more deviation than normal. Again, we're not using perfectly "clean" data. But even with the ITX oddities, no single board has pulled ahead of any other by more than a fraction of a percentage point.

The Pro4 acts similar to the MSI Z97I in the last roundup. It wasn't always the absolute fastest, but it used less power than its competitors to do the same work, so it wins the efficiency race.
