All the current articles are terrible, because none of them have independent benchmarks. Apparently, no-one got review units in time because of all the disruption, but AMD went ahead with dropping the embargo anyway.

Isn't it more like AMD dropped the embargo (partially) because Lenovo, ASUS and others wanted to get their devices out?
