How can A6000 beat PDAF? Can someone explain the technology behind this? It doesn't matter how many points of autofocus they put on the sensor it should still be significantly slower than dedicated sensors?

Why would it have to be slower? As long as the phase detect data can be read from the embedded pixels as quickly as they could be read from dedicated sensors, and as long as the autofocus processor is as fast, there's no inherent reason why OSPDAF shouldn't work as well as dedicated AF sensors.

Add to that the benefit of no possibility of back-focus/front-focus.
