AV1 is an amazing codec. I really hope it replaces proprietary codecs like h264 and h265. It has a similar, if not better, performance to h265 while being completely free. Currently on an Intel-based Macbook it is only supported in some browsers, however it seems that newer video cards from AMD, Nvidia, and Intel do include hardware decoders.

Isn't VP9 more comparable to h265? AV1 seems to be a ton better than both of them.

They’re all in the same ballpark of each other and have characteristics that don’t make one an outright winner.

AV1 is the outright winner in terms of compression efficiency (until you start comparing against VVC/H.266¹), with the advantage being even starker at high resolutions. The only current notable downside of AV1 is that client hardware support isn't yet universal.
