AMD has historically been very slow adopting new codecs, while NVIDIA has usually pushed it decently fast. But any speculation is just that.

AV1 has a major problem i forgot.
they changed the bit stream about 10 month ago. i don't have detail if thsi affects decoding but as far as i understand yes it did back then. maybe AMD cares more now since they are now entering the mobile market. taking recent development crashing with hardware decoding and the lying with polaris into account it will be intel or nvidia first. it's just speculation anyway. |

It does not. The errata-1 is exactly that, an errata to clarify some bitstream (mostly level) constraints. Actual decoding is not affected, it is just intended to simplify worst-case for hardware design. Actual non-cosmetic changes that I am aware of in the errata1: |

As usual, a new version of SVT-AV1 is released just in time for Phoenix to benchmark the previous 0.7 version on the new i9-10980XE and Threadripper 3960X and 3970X. (they unfortunately didn't have a Ryzen 3950X to benchmark)
https://www.phoronix.com/scan.php?pa...0x-3970x&num=8 Also included are benchmarks of rav1e v0.1 (1080p), dav1d v0.5.0 (1080p, 4k, and 10bit 1080p). AV1 performance-per-watt charts can be found on this page (scroll down): https://www.phoronix.com/scan.php?pa...x-3970x&num=12 ...and AV1 performance-per-dollar charts can be found on this page (also scroll down): https://www.phoronix.com/scan.php?pa...x-3970x&num=13

Phononix benchmarked the performance of Windows 10 vs Linux in both rav1e v0.1 and SVT-AV1 v0.7 on a Threadripper 3970X: https://www.phoronix.com/scan.php?pa...ws-linux&num=5

I'm also assuming that these decoders advertised as 4k60 capable are only capable of that in 8 bits. I would a bit surprised if that was not the case. So possibly they are not really ready for HDR content. And since AV1 is a codec for a time in the future when HDR could be common, that is dissapointing. I would think that since Netflix is pushing hard for it, at least 10bit 4k24 would be supported. |
