> In an 8-bit colorspace, h.264/5 suffer from virtually no block artifacts. AV1 can't get rid of them without upping to 10-bit. Not that it's necessarily a problem.
H.264 gets enough of a compression boost from 10-bit math that you should be using it anyway.
I don't know if this affects H.265

How are you measuring that?
It's true that SVT-AV1 is slower than x264 at preset 6 or below. And it's slower than x265 at preset 3 or below. But those aren't the presets you use if you want to be fast.
SVT-AV1 can match the quality of x264 veryslow while running at the speed of x264 veryfast.
It can match the quality of x265 veryslow while running at the speed of x265 medium.
It can match the quality of x265 medium while running at the speed of x265 ultrafast.
