I really wish PR and such would stop throwing around this "20-30% better than HEVC and VP9" stuff. There is no way to know if that's achievable or not yet, without mature AV1 encoders. And we know that the best HEVC encoders can outperform the best VP9 encoders by easily 20-30% for real-world scenarios, so a quote assuming VP9 and HEVC are equivalent just invalidates the AV1 comparison.

Honestly, finding real-world scenarios where libvpx can deliver better quality @ bitrate @ perf than x264 is a challenge, although I suspect that's primarily due to x264's massively greater psychovisual tuning and perf optimization efforts, not differences in the bitstream standards.
