2nd pass where things get more threaded, 2600k does 36 or so, 980x does 48, and BD scores 45 here.
Probably using all threads and can't consistently turbo, and pass 2 favors Intel a bit more.
Do you have a source for x264 bench?
I remember doing extensive benching on that benchmark some time ago with my x4. And I found that CPU NB clock OC gives biggest boost to that benchmark.
In 1st pass my x4@3.8ghz was kicking hard i7-920@3.8ghz. Wasn't winning but close. 2nd pass was a bit different story, thou still not far from i7 because of my tight timings and high NB clocks.
