Everybody compares AV1 to VP9 on 8 bits for both.

What about VP9 10 bits?
It makes also sense to compare AV1 8 bits vs VP9 10 bits.

VP9 10 bits has several advantages over AV1 8 bits at this moment:

Significantly faster encoding
Significantly faster decoding
Hardware support
Should has ~10-20% better compression than VP9 8 bits (not that far from AV1’s 25-30%)

It makes sense to employ VP9 10 bits at least for 2-3 years more until a final jump to AV1. It will give additional time for AV1 to develop better encoders and decoders.

Well, Google and Netflix already use VP9 10 bits for their HDR content but SDR could benefit as well.

Plus VP9 benefits a LOT from 10 bits because it suffers from blocking and banding not less than H.264 as it indicates here https://sonnati.wordpress.com/2016/0...ntion-part-ii/
