The bench is using the updated results from the newer drivers. It's not power throttled, it's just a slower chip. TPU, hardwarecanuks, techspot, anandtech, and the overwhelming vast majority of all hardware sites found the same results. The 1060 OC's a little better, uses noticeably less power, doesn't need any tweaks out of the box, and is faster almost all the time. AIB custom models are no where to be found, the RX 480 still only has the reference loud cooler. Obvious is obvious! :thumbsup: But glad you're happy with your purchase; that's all that matters.
The RX 480 4gb at $199 is a good alternative though.
