Phoronix: dav1d 0.8 Released With More Optimizations - More AMD Performance

Dav1d 0.8 was released this weekend (and subsequently 0.8.1 too) as the latest major release for this CPU-based AV1 decoder hosted by the VideoLAN project. Dav1d continues to be about offering the best AV1 decode speed and with the v0.8 series are even faster results -- so here are some of our initial data points as well from some weekend benchmarking...

Might be even better for my old non-AVX AMD:

CDEF in SSE

The CDEF filter alone is a third of the CPU load (before adding SIMD, at least I got a similar result): https://code.videolan.org/videolan/dav1d/-/issues/15

If you still have the Talos Power9 system, could you include it in more tests?

They will appear on the OB test profile page in the coming days, had been wanting to do so (and ARM) but the Talos II server is currently running other tests that won't wrap up for another day or so.

FPS doesn't seem to have changed much. Did power draw?

God bless these developers with Assembly skills!

Wow, I didn't really pay attention to these benchmarks for a while. I guess AV1 @ 1080p is now playable on just about any mainstream CPU from about the past 10 years?

I remember back when H.264 was still too slow to play 1080p smoothly, on a Pentium 4.

Considering my TV can do [email protected], it better be.

Wow, one of those tools in Summer Nature got a big boost, I wonder which one that was.

While the above charts tends to show more the shear performance of high end x86 systems, the real excitement is on the lower end x86 and with a lot of the arm tv box and sbc now having the ability to play most 1080p 8bit AV1 content that you may encounter, thanks to the work done by the dav1d team. Some higher end arm devices are even edging closer to doing watchable 4k 8bit decoding.

10bit decoding still needs a bit more to get really usable on arm, but is progressing well with each release as well.
