I am sure they are heavily biased toward speed over quality. Has anyone tried a bitstream analyzer?

Arctic Sound-M – Arctic Sound-M brings the industry’s first hardware-based AV1 encoder into a GPU to provide 30% bandwidth improvement and includes the industry’s only open-sourced media solution. The media and analytics supercomputer enables leadership transcode quality, streaming density and cloud gaming. Arctic-Sound M is sampling to customers and will ship by mid-2022.

Interestingly, this also implies that hardware AV1 encoding is a native feature of (at least) the large Alchemist die. Though given the potential value of the first hardware AV1 encoder, it remains to be seen whether Intel will enable it on their consumer Arc cards, or leave it restricted to their server card.

Looks like Intel Meteor Lake and later CPUs will get AV1 hardware encoder also since they have Intel Arc Tile GPU.

Consumer cards could also come with AV1 encoding support, it's known from the driver. However Intel could disable it artificially for the consumer DG2 similar to the AVX512 blocking with latest bios updates.

Promising. And Intel's never kept codec features to higher-end chips IIRC. The problem has been more the reverse; for years there were no GPUs in high-end Xeons so everything had to be done in software.

It's a pure fixed function AV1 engine and not just a hybrid, this is good news.


Here is a game stream demo versus H264.

Do we have any info about Intel's quality, or quality @ perf?

Yeah, I wish someone at a company that could use this info professionally would investigate.

Someone who got his hands on an a380 doing some encodings.

I hope the slower preset gives much better quality
